"To recap, there were two sets of malware: Set A, which contains malware from December 2007 to December 2008 (of which most products could detect over 97 percent), and Set B, which contains malware from the last seven months (1.6 million samples).

That said, here are the proactive detection results (rounded to the nearest percent): " – Content courtesy of AV-Comparatives picks eight proactive antimalware winners
