How to Protect Your PC from Viruses?

A small program designed to propagate itself and, sometimes, to cause damage or destroy the directory structure on your PCs are called worms and viruses because they share some of the traits of biological viruses. A computer virus passes from computer to computer like a biological virus passes from person to person. A worm is a computer program that has the ability to copy itself from machine to machine. Worms normally move around and infect other machines through computer networks. Using a network, a worm can expand from a single copy quickly. Computer viruses can be spread by infected programs downloaded from the Internet, or infected programs or files can be sent between computers by networks or by email attachments.
