Computer Viruses and How to Deal With Them

A computer virus is a software program that can replicate itself and spread from one infected computer to another. The infected objects can be a system, program, or document files. After infecting your computer, it might slow it down, damage the contents of the infected files, mislay the data, or defect your computer system’s normal operation. The virus can also use your computer to propagate illegal adverts and send spam emails that exploit security (adWare) and steal your personal information such as bank account numbers, credit card numbers, etc. (SpyWare). Some types of viruses might use your computer to create a botnet (virtual computer network) to attack other server systems and websites.
