A computer virus is a computer program that can spread across computers and networks by making copies of itself, usually without the user's knowledge.
Viruses can have harmful side-effects. These can range from displaying irritating messages to deleting all the files on your computer.
How does a virus infect computers?
A virus program has to be run before it can infect your computer. Viruses have ways of making sure that this happens. They can attach themselves to other programs or hide in code that is run automatically when you open certain types of files. You might receive an infected file on a disk, in an email attachment, or in a download from the internet. As soon as you launch the file, the virus code runs. Then the virus can copy itself to other files or disks and make changes on your computer.
