Computer Viruses

A computer virus is basically a form of software that, when installed, changes a few computer settings and installs its own personal code into those settings. When this infection succeeds in successfully changing a few settings, it is said to be infected with a virus. Viruses are very common, and many different types of viruses are in circulation.

Any computer system can become infected with a virus when a computer user visits a site which contains a file or attachment which has been infected with a virus. This can be through email attachments and files downloaded from the internet. It could also be because a Trojan virus has been downloaded accidentally, or because a rogue software application has installed itself on your PC. Once a virus has been installed onto your computer, it will spread throughout your system through the use of file copying programs, or via email attachments. The infection will then change the settings on your computer from time to time, and the virus will then send and receive emails. You will often see pop up windows and even a blue screen, but once you know you are infected, you need to remove the virus as soon as possible to prevent further damage to your system.

You should always have access to the latest anti virus and removal tools available. The best way to protect your PC against viruses is by making sure that your system is constantly updated with the most current versions. A good anti virus and removal tool are the one which has an extensive database of the top 100 infections as well as protection against other kinds of viruses. If you suspect that your computer might be infected, the best thing you can do is to download one of these tools and scan your system to find out what the problem is.
