Based on tests done by three renowned sites, I’ve concluded that BitDefender Antivirus Pro 2011 / BitDefender Internet Security 2011 is the best antimalware solution money can buy right now. It’s one of the top two in AV-Test’s report for April with 15.5 out of 18 points and full score in the protection test, it got an Advanced+ rating with few false-positives from AV-Comparatives in February and a high rating in Matousec’s firewall tests.
Prices start at 29.95$ for BitDefender Antivirus Pro 2011 (1 PC for 1 year) and 39.95$ for BitDefender Internet Security 2011 (1 PC for 1 year). Add 10$ for protection for 3 PCs. You can choose other combinations over at www.bitdefender.com. See the product comparison chart for differences between the two. Also check out their free online scanner.
