A computer virus is a software program that can reproduce itself and infect a computer. It can lay dormant for a specific period of time or it can become active creating real damage to a computer.

What is the typical way a virus infects a computer?

The various types of computer viruses (Source: are spread in many ways including:

  • Attachments in email or instant messaging messages
  • Introduction via external media such as CDs, Diskettes, or USB Flash drives
  • Files downloaded from the Internet

A computer virus first replicates itself by relocating on a legitimate program (eg. Word.Exe)and then attaching or splicing a copy of it into the genuine program. The virus’s code (i.e. Instructions) becomes a part of the legitimate program. When the legitimate program is opened (i.e. placed in RAM) the virus may activate itself then or at a programmed time.
