If you don't have a genius like Mike at Tri-City Computers to give you the most and best security measures possible, you need this! It includes Norton AntiVirus, Personal Firewall, Privacy Control, AntiSpam and Parental Control. It works with Windows XP Home/XP Pro/2000 Pro/Me/98. Box was never opened, but it was squashed some when a 113 pound Rottie sat on it. Rebate offer has expired--sorry!
