Without corporate IT staffs or gateway antivirus and firewall solutions, small businesses need some kind of protection from Internet dangers. These suites of apps provide antivirus protection, firewall blocking, and Internet privacy.

This year, we recommend ZoneAlarm Internet Security 5.5 over suites from Norton and McAfee because it offers the most complete Internet protection for your PC, without slowing down your machine.
