Just recently I have noticed that my Norton 2004 virus program suddenly disables itself. What would cause this? I have Windows XP Service Pack 2 installed. Would the windows firewall be shutting down my NV protection? Or could it be possible that I have a hidden virus on my computer that Norton hasn't found? I browse the internet, read email, and newsgroups alot, so I'm very concerned when I noticed that my virus protection is disabled. I'm the only one that uses this computer, so there is no way that anyone can disable the virus protection. Should I be alarmed? Or is this some kind of quirk of Norton 2004 virus protection?
