Norton never caught anything for me. But that was years ago... IDK I have over a year on McAfee, though I'm sure I'd get a refund... but what's to say I won't have issues with norton...it could be with the service pack 1 for vista and no one wants to admit it? hmmm if I don't get satisfaction with adv tech on phone... maybe I'll just delete the service pack and see if the problem clears.
