I'm just guessing. I use Sygate Personal Firewall and for antivirus I use AVG since it's been documented a number of times in PC Magazine that Nortons antivirus and firewall software products produce "false positives" on numerous occasions.
Thank you for the clarification. I've heard that about norton also... ran a Housecall scan the other day in fact because Norton came up empty but I have a file I can't delete and read it could be a worm or some sort. Housecall came up empty also, so I assumed it was wrong, but I still have this 0 byte folder I can't get rid of. Even downloaded MoveOnBoot, no fix.
