How do bug spread?

A computer infection is a kind of malicious code or program that, when performed, duplicates itself by modifying other computer system programs and inserting its own code. When this duplication is successful, the impacted locations are then stated to be infected with an infection.

Infections typically spread by developing a copy of themselves on a user's computer system without the user's knowledge or permission. In a lot of cases, infections will be spread by email attachments or by files shared on peer-to-peer networks. When a virus has actually contaminated a computer system, it can spread to other computer systems on the same network.

Some infections are configured to spread themselves in such a way that could trigger serious damage to a computer system.  other For instance, a virus might delete files, fill a hard disk drive with worthless information, or corrupt system files. In many cases, a virus might even display a message or image that is created to frighten the user.

Many infections are reasonably safe, and only cause small inconvenience to the user. Some viruses can be extremely harmful, and can cause prevalent damage to computer systems.
