How do virus spread?

A trojan horse is a type of harmful code or program that, when performed, reproduces itself by modifying other computer system programs and placing its own code. When this replication is successful, the affected locations are then stated to be infected with an infection.

Viruses often spread by creating a copy of themselves on a user's computer without the user's understanding or consent. In a lot of cases, infections will be spread out by e-mail accessories or by files shared on peer-to-peer networks.
