I'm using Antivir Personal Edition as my virus protection. At least half the time I turn on my computer, when Windows XP Pro finishes loading, I get a warning message from the Windows Security Center that Antivir Personal Edition is turned off. Sure enough when I check the Antivir Guard, it says "not active" next to service status. If I reboot, it'll sometimes turn on, but sometimes I have to reboot several times before it'll be active on start up. Anyone have any ideas on what the problem might be? This is getting really frustrating. I even did a reinstall of XP because I thought that might fix the problem, but it didn't. Would appreciate any help you can provide.
