I use the same as pac73 they work well. Don't like AVG 7.5 then get AVAST. Some prefer the way it works and looks over AVG. Choice is yours. Theres not really an overall winner. If you want a top performer you will have to pay and the best anti virus out there is probably NOD32. But AVG has kept me safe for about 3 years now as has Zone Alarm firewall.
