A computer system infection is a type of harmful code or program that, when carried out, reproduces itself by customizing other computer system programs and placing its own code. When this replication is successful, the affected areas are then stated to be infected with an infection.
Infections frequently spread by creating a copy of themselves on a user's computer without the user's knowledge or consent. In most cases, infections will be spread by e-mail attachments or by files shared on peer-to-peer networks. Once a virus has actually contaminated a computer system, it can spread to other computers on the same network.
Some infections are set to spread themselves in a way that might cause major damage to a computer system.

In some cases, an infection might even show a message or image that is designed to scare the user.
