I migrated my XP computer to a Vista machine. Zone Alarm Exteme Security moved over, but I get an error message saying that the anitvirus has been turned off and needs to be updated to reactivate. When try to update, I get a message that there has been an update error. Nothing seemed to work, so I tried to upgrade to the latest version. The upgrade canceled itself. I then tried to uninstall the version on the machine, but I got a message saying it was trying to verify permission to uninstall, but never moved beyond that.
