10 Tips to Make Your Computer Virus-Free - Computer Sciences Textbooks

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

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.

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.

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

So you thought that everything was going to be great when you upgraded to Internet Explorer 7 and that all of your web-browsing woes would have been finally laid to rest?

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.
