Many people believe that simply having their computer scanned weekly for virus is enough. Actually, while that is a good practice, it doesn’t prevent the virus from entering your computer system and infecting files. If the scan only occurs weekly the damage could have already occurred. In some cases, the virus changes things enough that the software will not detect the virus during the scan. Think about that little peep-hole that might exist in your front door. You wouldn’t let anyone into your home that you didn’t recognize, would you? So why let a file into your computer without checking it out first? In order to do this, you just simply scan the file on demand prior to opening it. If the scan results come back indicating a virus, you simply do not open the file and the antivirus software will guide you as far as what to do with the file. Also, make sure you scan email coming into your computer. This is an easy way viruses are spread.

Computer viruses can be devastating when their effects end up in the destruction of important computer files. That’s why you should always back up your important files or even digital photos. Some people I know make two copies and give one to a friend in the event of a fire or other situations that could damage the disc.

Transferring files can also pose a risk for infection. Say you use a flash drive to move files to another computer to work on. It is advisable to rescan the files prior to returning the updated files to your computer. It’s always better to be safe than sorry.

One method used is known as malicious activity detection. The antivirus software keeps tabs on the entire computer system. If there is any type of abnormal behaviour from any program, the software may begin monitoring it using another of these methods that will be mentioned later in this article.

Another method and perhaps the most well used is signature based detection. The anti-virus software contains a dictionary of the various signatures used by malicious computer viruses. What the software does is scan file contents. Then a comparison is made between those contents and the known virus signatures. When a match is made then the virus is detected.

A third approach is known as file analysis. With this method the antivirus software looks for files that have instructions contained within them that are similar to viruses. There are some drawbacks to this approach. In order for this method to work on your computer, the antivirus software must draw upon a significant amount of computer’s resources. This makes it difficult to do other activities when the software is running. This method also works well to identify new viruses and their offshoots. Like other methods, on occasion certain files are earmarked as malicious when they are not.

File emulation is another manner in which antivirus software detects virus infection. What occurs with this approach is that a program is run and the software monitors the actions of the software. Based upon these actions, the antivirus software can determine if the program is safe to your computer or if it is malicious and should be removed. This method has some disadvantages. Occasionally, sometimes the antivirus software can incorrectly mark a program as a virus when in fact it is not.

We’ve all heard of them, whether it be in the latest company newsletter about the virus attacking your bosses hard drive, or in the news that the latest computer bug will destroy all life as we know it, the computer virus can be an annoying thing, and whether we know it or not, most of us have ‘contracted’ a virus on our PC at some point, but how much do we know about them? For the large majority of computer users a computer virus is something for the ‘Tech Guy’ to deal with, and apart from installing anti-virus software there’s little we can, or can be bothered, to do.

A computer virus is basically a computer program that has the ability to copy itself and ‘infect’ a computer without the owner telling it to do so, or even being aware. The term “virus” is also commonly but wrongly used to refer to other types of malicious software such as malware, adware, and spyware programs. A virus in the true sense of the word can only spread from one computer to another when it is taken there, whether that’s over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses often increase their chances of spreading to other computers by infecting files on a network file system.

The advent of the internet has meant that viruses can spread much more easily, and regular outbreaks of certain viruses attack computers which are not properly protected by antivirus software . Viruses such as Sasser have in the past knocked out huge networks of computers, putting businesses out of action sometimes for days at a time.
