"New model-year security products used to come out in the fall, like new model-year cars. This year the first 2012 antivirus (G Data AntiVirus 2012 ($29.95 direct, 3.5 stars)) turned up way back in May. So far PCMag has reviewed nine antivirus tools explicitly identified as 2012 models, along with several others released during the same period. Which of these recent releases is the best?

Testing the Tools
To evaluate antivirus utilities I rely on hands-on, real-world testing. The malware removal test involves installing each product on a dozen malware-infested virtual machines and challenging it to clean them up. For the malware blocking test I attempt to install the same collection of threats on a clean system protected by the product being tested."
