Most antivirus sofware uses scanning technology that detects known viruses from a virus definition file. The limits of this outdated method are clearly visible with the advent of new viruses like myDoom, Sasser, Bagle. Millions of computers were contaminated by these virus though most were "protected" by an antivirus scanner.

These scanners have numerous disadvantages : they need constant updates (which require a subscription fee), they hog system resources and slow down the computer and the user is required to manually initiate virus scans. Viruses are then only detected once they are already on the computer !

Antivirus scanners are also unable to protect the computer against newer threats like spyware and Internet Explorer attacks.

The table below compares VirusKeeper with standard antivirus scanners:

	Antivirus Scanner	VirusKeeper 2008
Memory usage	30 MB to 130 MB	12 MB
