Coincidently, and for the time being, there is a thread not too far below yours, where the same question has been asked. Maybe you could also benefit from it?
"Which software to purchase for full security?" :
Additionally, I found another via the search function on top of the page. Seven pages worth of opinions. You may have to "poke around" some, but you'll get a flavor for what people think is best.
Enjoy the read..
I have used both McAfee and Nortons and have very interesting and individual problems with both (especial in regards to email filters and crashing my outlook). So now that I am at my experation date I was wondering what the best security program out there really is, with out going broke or throwing my laptop out the window in frustration!
