A virus is a computer program that finds its way onto a computer without the knowledge or consent of its user and, depending on the type of virus, can do considerable amounts of damage. Within minutes of the virus becoming active it might have tried to spread by sending out unsolicited emails to your friends, changed the settings of your system, corrupted important files so they are no longer retrievable, and maybe even made your computer unusable and reformatted your hard drive.

Since the first credited virus in 1982, malicious programs have become more and more commonplace, with many new ones being discovered every day. Although not all of them will cause damage to your computer, they can take up memory and cause problems with the way your system works, leading to poor performance or system crashes. Coupled with the risk of viruses, spyware has also become a problem when using the internet. Spyware is a program which secretly installs itself on your system and monitors your behaviour, and in some cases steals information from your hard drive and sends it to other people.

Antivirus programs, such as Symantec’s Norton Antivirus 2009, have been developed to combat the risk of viruses and spyware. By searching your computer’s files, scanning the registry and protecting emails, antivirus software will ensure that your computer is protected. It is important to be secure from newly discovered viruses, and as such, many antivirus programs have features to download the latest ‘virus definitions’ to combat emerging threats. Norton Antivirus 2009 has a tool called Live Update which will make sure that it is constantly protecting against all known infections.
