McAfee is considered as the best software to protect your computers from viruses. This software features VirusScan (tackle virus) and ScriptStopper (prevent virus to propagate from one computer to another via email) as well as WormStopper. On the downside it lacks P2P/file sharing protection, registry startup protection as well as instant message protection.

Installing McAfee is hassle free and the default settings provide very good protection against viruses, Trojans, worms, malicious ActiveX controls and Java applets. This software also features SecurityCenter, VirusScan tab, Personal Firewall+, Privacy Service and SpamKiller. Performance wise this software has the best virus detection record and it received the VB100% award for 2007, the ICSA award for 2007 and passed both level 1& 2 Checkmarks from West Coast Labs. Updating this software is easy as it automatically updates itself from the net which helps protect your computer from viruses.

As said earlier this is feature laden software as you can preprogram VirusScan to scan your computer against spyware and adware. The Antivirus Emergency Response Team monitors worldwide virus activities and guards against viruses, spyware and other Internet threats that may enter your PC via e-mail, instant message attachments; Internet downloads, and web browsing.
