Use Add/Remove and uninstall the AV first. Then the Live Reg, then the Live update. The last two may tell you that they've already been removed, and will remove the Control Panel icon.
When it's finished I recommend AVG free by Grisoft.
I got a new HP machine running Vista with I guess the most recent Norton antivirus. Subscriptions up and I wanna get rid of it. I saw here a few months ago that Symantec made it difficult to remove their stuff. What's the deal here?
