How do bug spread?

A bug 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 duplication succeeds, the affected locations are then said to be infected with an infection.

Viruses often spread by producing a copy of themselves on a user's computer without the user's understanding or authorization. In most cases, viruses will be spread by email accessories or by files shared on peer-to-peer networks. As soon as a virus has contaminated a computer, it can spread out to other computer systems on the very same network.

Some viruses are configured to spread themselves in a manner that might cause major damage to a computer system. A virus might erase files, fill a difficult drive with ineffective data, or corrupt system files. Sometimes, a virus may even display a message or image that is developed to terrify the user.
