Threats to customer data

A computer virus is a computer program that can copy itself and infect a computer without the permission or knowledge of the user. The term "virus" is also commonly but also used to refer to other types of malware, ad ware and spyware programs that do not have the ability to create itself again. A true virus can only spread from one computer to another when its host (some form of code) is taken to the target computer, for instance because a user sent it over a network or the Internet, or can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.

Viruses are sometimes confused with computer worms and Trojan horses which are like viruses but are technically different, in effect creating a damageable system to allow access to the user's computer. A worm can spread itself to other computers without needing to be transferred from someone, Worms and Trojans, like viruses, can cause harm to a computer system, functional performance, or networking throughput, when they are made.
