Protecting Your PC

What is a computer virus?

Computer Viruses, Antivirus Software A computer virus is a computer program that has been written to be self replicating. Some of viruses are comparatively harmless. Others corrupt or delete data. They are usually quite small in size. Viruses typically attach themselves to disk boot sectors, executable program files, or program macro files.

Viruses can be transmitted from computer to computer whenever files are exchanged either via downloads from the the Internet, from other computers on a network, or via diskettes or compact disks or other removable media.

Generally speaking you are more at risk when you receive programs that are in the public domain. Companies that are selling software products have more to loose if their customers become unhappy with them because their software has infected their computer(s). Consequently commercial software is typically more thoroughly checked for virus infections before distribution than is public domain software.

Should you get anti-virus software?

If you exchange files with other computers whether through the Internet, with friends, or purchase software from a store (that probably includes just about all computer users), the answer is yes. Preventing infection is much easier than trying to track done and eliminate a virus and then repair any damage that was done. Most anti-virus software is designed to detect computer viruses before they have a chance to do any damage or spread.

If your computer is behaving strangely, it does not necessarily mean that it has been infected by a computer virus, but it could be. It is best to check and know for sure. Most anti-virus software is designed to track and eliminate infections as well as prevent the infections.
