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..
