I saw someone post something (yes that is all I can remember) about INTJ's. So I looked up what it was, and I have come to the conclusion that most people in the Info Sec realm are this type of person, but please look around and see if you fit something else: http://typelogic.com/intj.html
One of the most under hyped av product on the market. It runs with less resources than bloated Symantec or McAfee and catches more than NOD32. For 9.95 you can't really beat it. But it goes back up to 30 bucks soon after black friday so get your copy.
