I looked here before buying a while back. Everyone (or many people anyway) here was recommending K@spersky, so I was going to buy it. However, you look at reviews on some of the big review sites, and see many negative reviews for K@spersky (paid for by a big competitor?), so I bought Nort0n instead.
Anyway, and all the Nort0n haters will probably love this, everytime I go to the main page here on bhw (all other pages don't show it), it shows that a virus has been blocked. I'm wondering if anyone else gets this as well.
