Security : Virus Checks

Viruses can get onto a computer from infected floppy disks, over a network or over the Internet. Virus checking software can be installed on a computer to examine all of the files that are accessed, checking them for viruses. If a virus is found the virus checker will attempt to remove it. The virus checker may not however be able to recover any data that has already been damaged by the virus.

Although the destructive actions of a virus are deliberately planned by the person who wrote the virus program, the introduction of a virus onto a computer system is usually accidental.

There is a separate article which covers viruses in much more detail.
