hmm I used to use McAffee in the windows 3 days, then with 98 I used Norton's but now on XP I find the best and least obtrusive (system resource wise) to be avast! and since it isn't on your list I didn't vote.... aside from that I run Zonealarm full suite minus the antiVir, win defender, spybot and AdAware <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
Yes I am paranoid also have a QOS on the modem with NAT working <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
