Web Link AVG Anti-Virus (Free)

This antivirus program offers rock-solid protection. AVG Free provides the bare necessities, including a real-time shield to prevent infections, anti-virus and anti-malware wrapped up in one engine, and a link scanner for Web surfing with care.

By default, the application is set to search for new virus definitions daily, but you can always use the scheduling tool to change this. Should a virus create serious system problems, AVG creates a rescue disk to scan your computer in MS-DOS mode. The program doesn't tax your system when scanning or when running in the background and always proved effective in our tests. The new interface is much easier to navigate than in previous version, with tabbed navigation on the left assisting users in drilling down to the tools they need.

Web Link Avast Anti-virus

Free virus protection for your home PC

New viruses are being found "in the wild" all the time. Further, the speed at which these new viruses spread is increasing all the time. A key problem is not that antivirus programs do not detect such viruses, but the fact that most users do not use any antivirus program at all or, perhaps worse, the antivirus software and / or virus definitions database is out of date.

ALWIL Software, the producer of avast!, decided in June 2001 to help to solve this situation by offering avast! Home Edition free of charge for home users who do not use their computer for profit. To get industry leading antivirus protection for your home PC, download the software, and then register it.
