What is a Computer Virus?
A computer virus is executable code that, when run by someone, infects or
attaches itself to other executable code in a computer in an effort to reproduce itself. Some computer viruses are malicious, erasing files or locking up systems; others merely present a problem solely through the
act of infecting other code.
Closely related to computer viruses are Trojan Horses and worms. A Trojan Horse is a
program that performs some undesired action while pretending to do something else. A Trojan Horse differs from a virus in that the former does not attempt to reproduce itself. A Worm is just a
self-propagating virus.
On personal computers, we recommend the installation and use of anti-virus software
capable of scanning disks, attachments to email, files downloaded from the web, and documents generated by word processing and spreadsheet programs.
Download Updates
Your anti-virus program is only as good as it’s latest update. Be sure
to download virus updates from the internet on a regular basis. Most programs include a scheduler which will do this for you automatically.
