10 Tips to Make Your Computer Virus-Free
By Pinky Mcbanon
The explosion in Internet use has brought with it the very real threat of viruses that can attack the unwary user. Viruses come in many forms - installers, Trojans and worms all of which can affect the performance of your computer and your privacy seriously. Viruses affect the computer either by corrupting programs or by replicating themselves and denying resources to legitimate programs. Trojans usually come disguised as something desirable and are activated when you try to open or run them. Worms and some Trojans may send themselves to people in your address book in emails, without your knowledge.
Even though the threat posed by viruses is serious, a few precautions taken in time can help you protect and sanitize your computer against viruses.
1. Browse with Caution - Most viruses enter your computer as a result of clicking on pop ups or other links in websites that are not trustworthy. Do not follow links or click on pop ups that could install viruses on your computer.
2. Open Emails Cautiously - At times, even if the subject is innocuous, emails can contain links that lead to a virus entering your computer. If the email is not from a trusted source, treat it with caution.
3. Open Email Attachments with Care - The attachment that the email urges you to open may contain a virus! Make sure your mail manager allows you to preview the type of file (.exe, .com, .vbt in attachments are probably viruses. The same goes for screensaver programs that come to you unsolicited).
4. Installing downloaded programs - Programs downloaded from the Internet can pose a serious threat to your computer. Make sure that the program you have downloaded is from a trusted site or has a certificate issued by a trusted certifying authority.
5. Firewall - There are several firewall software packages available that allow you to prevent unauthorized access to your computer that could be initiated by an infected system.
6. Antivirus - A good antivirus package residing in your computer can be the best protection you can have against viruses. Choose an antivirus package that can comprehensively defend itself against viruses.
7. Regular Virus Scan - The mere presence of anti-virus software in your computer is not enough. Scanning of your computer for viruses must be done on a regular basis to locate and isolate viruses.
8. Update the Anti-Virus - It is very important to update the anti-virus program itself periodically. New viruses are introduced every day and the manufacturers of the anti-virus software update the virus database and capabilities of the anti-virus program regularly.
9. Update windows and all other software - Do not forget to update the Operating System and other software regularly as they are frequently patched to overcome security loopholes and vulnerabilities.
10. Removable Media - Removable media like floppies and USB drives are a major factor facilitating spreading of viruses. Use only trusted devices on your computer.

Never Click on That Ad, Spyware Programs - Computer Sciences Textbooks
Never Click on That Ad, Spyware Programs
By: Manish Sachdev
Today so many industries use Spyware programs as a way to advertise. These programs are designed to be click on or automatically re-rout you to the advertiser’s website.
Other types of programs are the annoying pop ups you get on your computer screen. Some of these programs are capable of tracking which keys you type thus for computing exactly what you are saying or typing. This is how hackers are able to obtain your private and personal information. With programs such as these you may not know who has your personal information or even worse what its being used for.
It is annoying, but being educated on the signs of spyware and how to protect your-self from it is a great way to keep your-self safe from the hassles and fears of these malicious programs.
There are several ways to know if you have spyware on your computer: You continue to get tons of pop ups even when your pop up blocker is activated. When you put in a specific website you are redirected to a different site. Also new and unexpected icons on your tool bar can be a sign of malicious software. You may experience lagging due to these programs and the computer trying to process all of the information. This lagging can be stopped by practicing good protection against viruses.
There are many anti spyware programs but some viruses may bypass these programs. So to keep you and your computer safe from the hassles of spy-ware here are a few easy tips.
1. Don't click links in a pop up box because in most cases these are malicious and may automatically download to your computer with or without your knowing. When closing a pop up box refrain from pushing anything inside the pop up box itself this could again download a program without you knowing it. Try to push the red X and if you want to refrain from touching the pop up box then right click the pop up box and click Close. If an error message comes up that you are not familiar with click the X or NO. Only if you know what the pop up box is can you click yes. But sometimes familiar looking error messages are just concealed spy-ware.
2. Beware of pop-ups or web pages that tell you your computer may be infected, or that they can help your computer to run faster. NEVER click on these or you will become infected with spyware / adware.
3. Do not download free screensavers or smiley faces. These free programs usually come with adware / spyware hidden in them.
4. Do NOT use file or music sharing software. Most file sharing software is embedded with adware/spyware. Many times the software will claim it has no spyware / adware, but that CLAIM is sometimes false. Also it is very easy to download a program or a music file that someone is sharing and get infected with spyware or a virus that could destroy your data.
By using these tips you can keep your computer and yourself safe from all of these malicious programs. Now you can defend yourself from the Internet at least a little bit and go back to enjoying the comforts of the Internet.

How to Get Rid of Trojan Virus - 5 Easy Steps to Get Rid of Trojan Horse Virus - Computer Sciences Textbooks
How to Get Rid of Trojan Virus - 5 Easy Steps to Get Rid of Trojan Horse Virus
By Jake Unsworth
Before we can know how to get rid of trojan virus we need to specify exactly what it is and how it differs from a normal computer virus. A trojan horse virus is a form of malware (malicious software) that leaves your computer open to attack, and derives its name from the famous Greek legend of The Trojan Horse.
The Trojan Horse was used by the ancient Greeks to trick their way into the once impregnable city of the Trojans (Troy) and secretly send in soldiers to open the gates and allow the rest of the Greek army in to take over and conquer the city.
In the same way, computer trojan viruses disguise themselves as seemingly harmless pieces of software or desired files, but then "open the gates" to other forms of malicious software, spyware, keyloggers etc...leaving you open to anything from someone stealing your credit card information, to some basement-dwelling geek gaining remote access to your computer and files. So the trojan virus' real damage is done in its ability to compromise your computer's security and leave it open to other dangers.
So while a normal computer virus is lethal in itself and can "mutate" and infect other parts of your system, the trojan allows other digital nasties in through the back door. The good news is that this makes it easier to identify and get rid of trojan virus.
How did you get the trojan virus on your computer?
As mentioned above, the trojan virus is often disguised as a normal looking file, so maybe it was an mp3 music file, a patch for a game, an online video, or even a jpeg image file. Either way, it's on your computer, so how do you get rid of trojan horse virus?
Here are the 5 things you need to do right now to get rid of trojan horse virus and avoid it returning:
1. Make sure your anti-virus software is up-to-date and includes all the latest patches and virus, spyware definitions. This will be your first port of call when trying to get rid of trojan virus.
2. Run a system and registry scan to identify the evil trojan virus and then zap it into oblivion to get rid of it. Since it resides within an unimportant file you can easily delete it to get rid of trojan virus - whereas other computer viruses are more tricky to get rid of and need to be "quarantined" to stop them infecting other files on your system.
3. If you know the name of the trojan horse virus then you can check online for information on how to get rid of the trojan virus in question. Microsoft has regular updates on it's site about trojan viruses that affect Windows machines. Online forums also provide you a wealth of information about how to get rid of a trojan horse virus.
4. You could also try to get rid of the trojan virus manually. Check your Task Manager (press Ctrl +Alt +Del on Windows) to identify any programs that may be running in the background that shouldn't be - i.e. they started without your knowledge. If you see any such program, make a note of it's name, click its name to highlight it and click End Task. Open your Control Panel (click the Start menu) and use the Add/Remove programs to find the nasty blighter in question and get rid of it. Be careful with this though as you may end up wrongly deleting a file that is important to your system.
5. Overall you should take a look at your online habits and see how certain actions may compromise the security of your computer and your personal information. If you use Peer-2-Peer (P2P) file-sharing networks then take extra care on what you download, and make sure everything is run through your anti-virus / spyware scanning software first, to get rid of trojan virus that may be attempting to access your system.
How many of your personal details do you enter on your computer on a regular basis? For instance, do you bank online, or pay bills or a credit card? Perhaps you buy gifts and other purchases online? According to CNN, if you use the internet there is a 90% chance that your computer is infected with spyware. How can you be sure that your information is not being viewed by a third party right now?

What Is Computer Virus ? - Computer Sciences Textbooks
What Is Computer Virus ?
Submitted By: Alex Kubik
A computer virus is a malicious computer program that, when executed by an unsuspecting human, performs tasks that primarily include replicating itself and in some cases deploying a payload.
A decade or so ago, viruses were pretty simple. They got into a system and infected a file or two. It was a basic as ordering coffee when coffee was easy to order. "One coffee pleaseblack."
Today, the catalog of viruses you have to defend yourself against is frighteningly complex. In fact, it's become as complex as, well, ordering coffee.
"Looks like you've been infected by a dropper that's put a Trojan on your system, which deployed a multi-partite that opened a backdoor and also infected the master boot record."
Sounds like an order at Starbucks, don't you think?
These days a discussion about a virus can actually occur without using the word virus because sometimes viruses are worms or Trojan horses, which are virus-like nasties that act a little different than their infectious cousins.
Why are they called computer viruses? Well, because they have similar characteristics to biological viruses that infect humansin at least one way. The computer variety jumps from computer to computer much like a cold virus jumps from your kids to you and from you to your spouse.
Don't let all this frighten you, though. It's not that hard to figure out and defending your computer against viruses is pretty straightforward. Still, if the idea makes you queasy, skip ahead to the part of the chapter about how to easily protect yourself from viruses. But I hope you stick around because the more you know, the geekier you will be. Okay, not really. But understanding them makes them much less scary.
Viruses were one of the first real security threats people had to deal with when personal computers started appearing in homes a couple of decades ago. The first computer viruses were written in the 1980s; however, they really didn't become a big threat until the late 1990s when everyone who owned a personal computer started connecting to the Internet.
Before then viruses spread via floppy disks or CDs. They would ride on the back of files stored on a disk or in the boot area of the floppy and replicate when the disk was inserted into the computer.
The Internet's popularity has also become the chief reason that security on personal computers has become such a hot topic. A Net connection is the off-ramp from the Internet into your computer for all data. And guess what? For viruses it's an express lane.

Computer Business Software - What Should You Buy? - Computer Sciences Textbooks
Computer Business Software - What Should You Buy?
Computer business software is an area where many new network consultants get overwhelmed. There are so many great products out there that it is hard to decide which computer business software to invest your time and money in.
You want to be able to expand your capabilities but you don't want to sink too much time or money into any computer business software purchases until you know you have a market for them. Because computer business software is an investment, you need to think carefully about the programs and packages you purchase.
If you think in terms of whether the business computer software will attract and appeal to sweet spot clients, you are thinking on the right track. You want to ask yourself, "If I invest eight hours in learning this and invest a few hundred dollars in some training or not-for-resale product, am I going to make it back?"
There are two computer business software products I recommend you look at seriously for sweet spot clients.
Microsoft Small Business Server (SBS) Novell’s Small Business Suite
Why I Recommend This Computer Business Software: Both of these computer business software products are inexpensive buy-ins. You're not going to have to spend a lot of money to get a demo or not-for-resale copy for you to learn with. For a few hundred dollars you'll have most of what you need. With both types of computer business software, you should be able to take eight to ten hours and feel comfortable installing it, breaking it, and then reinstalling it.
I recommend that you just pick one of them. Don't try to support both types of computer business software at the outset unless you already have really strong skills on both Windows and on Netware, and you want to support both of them right off the bat.
Use the computer business software you choose to run your own business. Sooner or later, probably within a month or two, you'll feel comfortable enough to do a simple installation for a client.
Bottom Line on Computer Business Software Always think of computer business software as an investment. You need to make sure you will recover, and then make a return on, the time and money you put into acquiring and learning new computer business software. If you stick to Microsoft Small Business Server (SBS) and Novell’s Small Business Suite at the start, your computer business software investment should pay off pretty quickly.

The Most Common Computer Problems
By Scott Hannon
I do not have to tell you what the most common computer problems are, especially if you are experiencing them right now. However most people who own a PC do not understand that their are common computer problems that you will begin to experience as your system becomes older. It does not mean that you need to run out and purchase a new system; however it is best if you are familiar with the problems and then find out how to fix them.
Your Computer Keeps Freezing Up: We have all most likely seen our computer freeze up, that it is impossible to even get the cursor to move. So while we leave the computer for a while and hope that it will do its thing and then you will be able to get back online to finish what you need to do; however sometimes it does not become unfrozen; that you have no choice but to turn off the power button. It is not recommended that you do this all the time; however sometimes this is the only way to get it to function properly.
If you are experiencing your computer freezing up all the time; then most likely it is suffering from some type of maintenance problem. Unfortunately the sad fact is that over 80% of people who own computers do not know how to properly take care of them.
Blue Screens When You Move Your PC: I had this problem with one of the laptops that I owned. It seemed as though every time I got into something important; my computer would just freeze up or even worse the screen would turn totally blue. It could mean that your current computer has a short or you could have acquired a computer virus.
Most computers are meant to last at least 6-7 years. However most people do not realize how important it is to learn how to keep it maintained. Instead of trying to learn the proper methods to keep it working; they are willing to spend thousands of dollars to purchase a whole new system. The truth is that eventually as your new computer becomes older; then you will face the same problems again.
Strange Noises Or Vibrations: These are most likely due to a hardware issue. It could mean that the cooling fan on your computer is defective. Another thing you will want to check when you are experiencing noises coming from your system; is to ensure that the power supply is hooked up properly. You will be amazed at how many people fail to realize that sometimes they do not have it correctly connected.

Where Do Computer Viruses Come From? - Computer Sciences Textbooks
Where Do Computer Viruses Come From?
By Dawn Smith
Computer viruses become a threat for most computer users. But have you ever asked yourself "where do computer viruses come from"? Perhaps with this knowledge you will be able to enjoy all the benefits of your PC without becoming a virus victim.
Behind every virus is a computer programmer. They create viruses for a variety of reasons. It may be to demonstrate skill. It may be eager students seeking admiration from their fellows. But more often than not viruses are created by cyber-criminals. They are designed to steal or copy your personal data for financial gain. It may be to gain access to passwords or credit card details. It may be to use your internet connection without your knowledge for illegal purposes. Or it may just be to bombard you with spam and bogus advertisements.
So viruses can be simply annoying or they can lead to financial ruin. Either way they are something we all need to steer clear of and we can do that by knowing a little more about them.
The most common source of virus infection is of course the Internet, this will not be a surprise and it doesn't mean that you have to stop accessing the Internet either. Most of the people who do unknowingly catch viruses from the net do so because they are click-happy. By this I mean they will click around and download anything on offer without knowing whether or not they can trust the source.
Here's a simple tip: Before you click on a link, check your status bar (usually bottom left) and see where it points to. Also make sure you don't install any programs unless you are confident you know what they are and where they have come from.
Email and email attachments are the second most common tool used to spread computer viruses. Email attachments must be handled with a lot of caution and you must not open any attachments that come with an email from an unknown sender. If you have a good anti virus package then you will be able to scan attachments before you view them. Make sure you do this even if it's from a friend. They may have unknowingly forwarded a virus to you.
Another very common way in which the virus spreads is as part of a bundle with cracks and key generators. Generally these are offered on peer-to-peer networks that have illegal file-sharing programs. The victim would be lured with downloads for free software only to find they were installing a virus on their own system.
The main thing is not just having a good antivirus on your computer, it is to keep it up to date because new viruses are created all the time. Again, a good anti virus suit will update itself regularly.
Hopefully this has answered that burning question "where do computer viruses come from"? Just good anti virus software and a bit of common computer sense is all you really need to stay safe from computer viruses.

One good source of free virus protection is offered by search engines. See Free Yahoo Virus protection for a good example of this.

Internet Explorer 7 Problems
By Hugh Kent

Despite having downloaded to the latest stable release of Internet Explorer 7, problems are bound to occur, such as:
The web browser temporarily hangs / freezes up / locks up while loading certain webpages, such as those that use the contain Adobe Acrobat Reader plugin or any pages that contain client-side Java applets.
Web pages take an unacceptably longer time to load than is normally expected, even if you have rebooted your machine or you are on a high-speed Internet connection.
The web browser stops responding completely, and refuses even to terminate even if you attempt to kill its process through Windows Explorer.
The web browser spontaneously crashes and stops running.
Determining what causes Internet Explorer 7 problems is just as much a mystery now as it has always been with previous versions of this web browser.
Believe it or not, the vast majority of Internet Explorer 7 problems have nothing to do with the speed of your Internet connection, or your computer's memory or CPU.
On the contrary, most typically, the cause of this type of problem is usually one of the following:
You have inadvertently downloaded rogue spyware onto your PC from some rogue pop-up banner from some website that you recently visited.
You may have inadvertently unleashed a virus onto your system through some file you have downloaded or some e-mail attachment you opened up.
Your computer's hard drive may be severely defragmented.
Your Windows registry may be corrupted or in dire need of reoptimization.

How to Get Rid of Virus on Your Computer - 3 Tips to Zap That Virus! - Computer Sciences Textbooks
How to Get Rid of Virus on Your Computer - 3 Tips to Zap That Virus!
By Jake Unsworth
Today, knowing how to get rid of a virus is essential for anyone who regularly uses a computer. While the internet continues to grow in popularity at what seems a blistering pace, more and more of our life seems to be moving online - working, shopping, playing, banking etc.
While this is great, it also leaves us open to attack by more and more unscrupulous so-and-so's who like nothing better than to infect your computer with a virus, spyware or other malicious software...sometimes for harvesting your personal details, or simply just for the heck of it.
This is becoming so common that many folks want to know how to get rid of a virus on their computer, without causing any further damage to their system or loss of important personal information.
Before I show you 3 easy ways to get rid of a virus on your computer, I think it is important to define exactly what we mean by computer virus, as this will determine what strategy we use to get rid of it.
While many people broadly speak of a "computer virus", there are many ways that your computer can be infected with a virus-like piece of code or software. According to Wikipedia, "A computer virus is a computer program that can copy itself and infect a computer without permission or knowledge of the user." However, the category of virus has now grown to include almost any malicious software (malware) and adware (often a harmless piece of software that hides on your computer and displays ads while you're browsing on the internet).
Traditionally, computer viruses required some kind of manual operation to enable them to spread to different computers, i.e. as part of a file sent to another machine, or via a floppy disk, usb key, etc. However, once on the host computer they can "mutate" and replicate, thereby infecting other parts of your system. Other malware that has come to be regarded (erroneously) as computer viruses now are things like worms and trojan horse viruses, which can infect machines on their own - worms through a process of "burrowing" into a system; and trojan horse viruses by disguising themselves as harmless files, while containing malware and spyware like keyloggers and other nasties that can harvest your personal information without you knowing.
Of all of them, it is still the traditional computer virus that can cause the most havoc on your computer, as it can run through your whole system and destroy everything. It can also be the trickiest to get rid of, since it is not often a single file that can just be deleted, or it has become entrenched within your registry files and cause damage to your entire operating system. So how can you get rid of a virus on your computer without causing even more damage? Here's 3 easy things you must do right away:
1/ Do A Virus Scan Immediately
To get rid of the virus you should run your anti-virus program and do a full system and registry scan. This can often identify the nasty virus and then "quarantine" it to prevent it infecting other parts of your system. If you don't have any anti-virus software to get rid of the virus, you can perform a free scan by clicking on my link at the bottom of this article.
2/ Do You Know What The Name Of The Virus Is?
Sometimes the name of the virus can be identified through your anti-virus program or it identifies itself through certain actions or dialog boxes. This can be extremely useful, as a quick look online can yield the exact solution to get rid of that particular virus. If you're using Windows, then Microsoft will have all the latest info and download patches to get rid of recent viruses.
3/ Run Another Virus Scan To Check
Running another scan will enable you to verify that the nasty virus has been taken care of, and you can rest assured that it should not cause any further problems. Performing regular scans every week or so is good practice to limit the potential of any returning virus.
Bonus Tip:
Be careful about what you download, particularly if you use Peer-2-Peer sharing networks or Torrent sites. Hackers and other rogues often hide malware and viruses in these kinds of files, as most folks wouldn't expect it. Even if the file is coming from a friend, they may have downloaded it themselves and not realised that it contained the malware.
Best practice is always to make use of an anti-virus software that will scan all downloads and get rid of virus threats before placing them on your system.
How many of your personal details do you enter on your computer on a regular basis? For instance, do you bank online, or pay bills or a credit card? Perhaps you buy gifts and other purchases online? According to CNN, if you use the internet there is a 90% chance that your computer is infected with spyware. How can you be sure that your information is not being viewed by a third party right now?

Spyware - Is Your Computer Infected?
By Tasi U Feite
There will be many or, to be more accurate, hundreds of adware on your personal computer and it is almost impossible to ensure that your PC is never infected with it. Some simple things to be aware of when you're surfing the Web are, to know what sites you visit, what sites your children visit just to start with. When you get pop ups appearing all of a sudden and your Browser has not blocked it, though it is set to block pop ups and give you an option to allow or not, then it is more than likely you have spyware.
Removing Adware and the likes is now a must for every cmputer or laptop. It is important you consider adware removal daily if you or others surf or check emails every day. Though adware is, in most cases harmless, it maybe transmitting information about the sites that you visit when you're online to advertisers or other organisations that collect data about people and their web surfing habits to sell to advertisers. You may then find that you are receiving all these ads or emails from companies or people you don't know anything about. Time to seriously consider a good Adware removal program.
I found out about adware and the likes quite by accident. I was surfing one day after checking my emails when all of a sudden I ended up in some adult entertainment site. Man was I surprised at what people could view on the Net. Then I started getting all these emails, guess what, they were from people who obviously frequented and promoted these adult sites and I couldn't get them to stop sending me emails. I replied to all of them many times to request they stop sending me their crap emails, it never stopped. What eventually happened was my computer crashed. There was not much I could do so a technician advised it was to late to recover, so it had to be formatted, my hard drive that is.
Hackers don't worry to much about what you want or don't want on your PC. You must at all times be weary of any adware, spyware and the likes possibly infecting you computer. Take responsibility and protect yourself and family from adware. Start by using available protection that comes with your windows operating system. Also you will find that your ISP, internet service provider may have programs available as part of their service.
Should you conclude that adware removal software is definitely a must for your PC. You may be surprised at what shows up when you first run the program on your computer. some adware removal programs will also pick up cookies from some sites that use them. If you remove the cookies, this might mean that you just have to sign in again to all of the sites that you may have set to remember you when you return. You can opt out of removing those. That is entirely up to you.

Computer Software and Anti-Spyware
By Jesse Miller
When you think about the internet you associate the concept with a huge amount of information. What happens if this information contains malicious software designed to breach you security and provide other people access to you personal data? In this case, we can call this malicious software a spybot. There are several ways to deal with this problem, either you download free spybot tools or you try to find a more active tool, for example an anti spyware software.
In any case, the decision is up to you and in both cases you are guaranteed a complete removal and sanitation from these pesky problems. A good example of passive aggressive software could be Spybot Search and Destroy. It doesn't provide active and immediate response to immediate threats, but it can definitely remove any intrusion after a thorough scan.
For a more active approach, there is free spybot software that regularly comes hand in hand with an antivirus monitoring system. This also is a good choice mainly if you don't run regular scans on you system. In order to get the best of effect, my advice to you would be to install both applications. Even if something eludes the first one, on a thorough scan with the other nothing will be able to escape. So, for the record, computer software and spyware tools are a must have when it comes to protecting you virtual identity and no matter, licensed or free, they both work as long as they get the job done.
If you really want to take the work out of looking for that right Spyware Protection from a Spybot go to the Internet and get a Free Spybot Download or a Spybot Search and Destroy to prevent your vital information from being ripped from your computer.

Once you have diagnosed the virus, do a little research - if it's a hard hitter - there will be specific details on how to deal with it online.
Update your anti-virus software - most companies have daily updates, make sure auto update is switched on. If your computer has been compromised before you could successfully update or install anti-virus software, it becomes a little more difficult.
If you can locate the hard drive inside your PC, you may wish to extract it and link it up too a spare PC for repairing. Opening your PC may breach your guarantee if you purchased a package computer. Not much of a guarantee - they make sure you have to pay them to repair it!
When connecting up a corrupt hard drive to a new system, avoid at all costs running any programs or files on the drive. This will just cause the virus to load and spread, simply boot up like normal and scan the newly detected drive completely.

Computer Virus - Remove Infections
By Alex Redbridge
It astonishes me how many people ignore the signs of a computer virus, remove infections now or deal with the consequences!
With the development of Windows, the more usability it creates - the easier it is to compromise with virus code. This is why big corporations and banks use specially developed platforms - Windows is just too much of a gamble when dealing with customer accounts.
It's very difficult to pinpoint an exact method for dealing with a computer virus. This is due to the various versions and species that have evolved over the last generation. There's one clear cut way to wipe out any problems - that's with a computer hard drive reformat.
Not the most practical solution now is it? This may well be all that your left with if you've allowed an infection to spread - causing your PC or laptop to not even turn on.
First step to conquering an attack would be with a virus scan - find out what the virus is called. If it's a wide spread epidemic, there might be more information about the specific virus.
Update your anti-virus software and give your whole system a scan - this might take some time but it's worth the wait. If you don't own any anti-virus protection and actively use the internet, especially to download - you need to seriously look into installing some defense.
Hopefully your system has been restored with the updated or newly installed anti-virus software. It's possible that the infection has disabled or blocked the software from working / installing.
Having access to another PC is useful if you can locate the hard drive inside your system. Unplug the power and remove the hard drive with a screwdriver. Connect the corrupt hardware to your PC and use the virus scan to remove the infection.
Beware that you do not run any applications on the corrupt hard drive - this could cause your secondary system to become infected.

Spams and Their Filtering Techniques - Computer Sciences Textbooks
Spams and Their Filtering Techniques
By Musa Aykac
We are all familiar with word Spam. This is something we encounter almost on a daily basis in our mail inboxes. They waste our precious time and also contribute in spreading malwares. It is expected that in the year 2008, as many as fourty trillion spam messages will be sent across the globe. This is significantly higher than the figure in 2006, when it was 18 trillion messages.
All of us are aware that email filtering software separates good or true email from the rest or spams. But these software or other appliances employed for filtering can go wrong. While a true mail may be blocked, a spam mail can easily pass through the filter to reach your inbox. If a spam mail is successfully filtered, it is generally placed in a separate folder. These folders can be searched later by the user. According to few sources, both individual users and organizations stand to lose not only their energy and time in deleting these spam mails but also have to shell out $0.4 per deleted message. This figure has been calculated after a lot of calculations and predictions by analysts.
Popular filtering techniques
A number of spam filtering mechanisms have been employed over the years to counter it effectively. Occasionally, more than one techniques are also employed. Some of these include:
1] Tarpitting:- These are services on the server which takes a lot of time establishing incoming mails. This technique ensures spam mails will take a lot of time to reach a recipient, thus discouraging the spammer to carry out his task. However, the disadvantage is that the same procedure hampers the true mails as well.
2] Graylisting:- In this case, the recipients mail system temporarily rejects all incoming mails. Reciprocal mails are sent as reply with the content being quoted as temporary failure. This technique is employed with the assumption that a real mailer will respond back by sending the mail once again while the spammer loses his patience and will give up on sending further spams.
3] Challenge response:- This technique employs CAPTCHA method to its routine. Mails from unrecongnizable IP addresses are asked to enter the sent CAPTCHA. Humans are able to detect these patterns while the computer fails to do so.
4] Bayesian filters:- This technique analyses the ratio of "good" and "bad" words and assigns a score to each one of them. Based on these scores, spams are filtered out.

What is Computer Security?
Computer Security is a branch of technology known as information security as applied to computers. Information security means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction. The objective of computer security varies and can include protection of information from theft or corruption, or the preservation of availability, as defined in the security policy.
Technological and managerial procedures applied to computer systems to ensure the availability, integrity and confidentiality of information managed by the computer system
Computer security imposes requirements on computers that are different from most system requirements because they often take the form of constraints on what computers are not supposed to do.
Typical approaches to improving computer security can include the following:
Physically limit access to computers to only those who will not compromise security.
Hardware mechanisms that impose rules on computer programs, thus avoiding depending on computer programs for computer security.
Operating system mechanisms that impose rules on programs to avoid trusting computer programs.
Programming strategies to make computer programs dependable and resist subversion.
Computer Security has three Layers:
o Hacking
o Cracking
o Phreaking
Hacking:
Unauthorized use or attempts to circumvent or bypass the security mechanisms of an information system or network.
Computer hacking always involves some degree of infringement on the privacy of others or damage to computer-based property such as files, web pages or software. The impact of computer hacking varies from simply being simply invasive and annoying to illegal.
Cracking:
The act of breaking into a computer system.
Software Cracking is the modification of software to remove protection methods: copy prevention, trial/demo version, serial number, hardware key, CD check or software annoyances like nag screens and adware.
The most common software crack is the modification of an application's binary to cause or prevent a specific key branch in the program's execution.
Phreaking:
The art and science of cracking the phone network.
Security by design:
The technologies of computer security are based on logic. There is no universal standard notion of what secure behavior is. "Security" is a concept that is unique to each situation. Security is extraneous to the function of a computer application, rather than ancillary to it, thus security necessarily imposes restrictions on the application's behavior.
There are several approaches to security in computing; sometimes a combination of approaches is valid:
Trust all the software to abide by a security policy but the software is not trustworthy (this is computer insecurity).
Trust all the software to abide by a security policy and the software is validated as trustworthy (by tedious branch and path analysis for example).
Trust no software but enforce a security policy with mechanisms that are not trustworthy (again this is computer insecurity).
Trust no software but enforce a security policy with trustworthy mechanisms.
12 tips for computer security:
Update / patch ALL your software every now and then!
Check / adjust ALL your settings so they are safe, since they ARENT by default!
Use firewall, like ZoneAlarm to control what goes in and out from your computer!
Use good passwords: at least 13marks long, containing both letters and numbers. Remember to change your password every few months atleast and dont ever use the same password in two places!
Get a good antivirus program: NOD32, F-Secure or Norton Antivirus and keep it updated!
Don’t open or execute files that you are not 100% sure are absolutely safe nomatter where or how you get them.
Wipe your historyfiles (like cookies, internet history and temporary files, etc.), logs and personal files, with specific wiping program (like Eraser) instead of just deleting them.
Use encryption to enhance your privacy! Use encrypted email (like Hushmail or Ziplip), www-surfing and encrypt sensitive files on your computer (PGP).
When you are finished using some internet-based service like email, sign out of it rather than just closing your browser! Also, when you leave your computer, make sure that none of such programs or connections are left open that someone could abuse. In WindowsNT/2k/XP, press Windowskey+L to lock the workstation.
Don’t use public computers for anything you need to type in your logins, they usually have Trojan horses that capture your passwords.
Make backups and store them in safe place! Easiest way to do a total-backup is to make an "Image" of your harddrive or partition and store it on safe location, but floppies will usually be just fine for storing documents, etc.
Install and Use a Hardware Firewall
