How do virus spread?

A bug is a type of destructive code or program that, when performed, replicates itself by modifying other computer system programs and inserting its own code. When this replication prospers, the affected areas are then said to be contaminated with an infection.

Infections frequently spread by producing a copy of themselves on a user's computer system without the user's understanding or authorization. In most cases, infections will be spread out by email attachments or by files shared on peer-to-peer networks. As soon as a virus has actually contaminated a computer system, it can infect other computer systems on the same network.
