In order to pass Virus Bulletin's test, the submitted products were required to detect all malware known to be "In the Wild" via both on-demand and on-access, without reporting any false positives. They were bombarded with some 3,000 unique samples of four malware types: WildList viruses, worms and bots, polymorphic viruses, and Trojans.
Although Avira and Sophos' products failed Virus Bulletin's test, they only missed one malware sample out of the thousands faced -- in order to receive a VB100 award, applications must detect 100%. That said, Avira told Ars Technica that the issue was sorted before VB's results were published.
Ars has posted a complete list of results for all products tested, which you can view after the jump. Pass: Alwil avast!, AVG I.S. Network Edition, BitDefender Security, CA eTrust, eScan Internet Security, ESET NOD32, F-Secure Anti-Virus, G Data AntiVirus, K7 Total Security, Kaspersky Anti-Virus, McAfee VirusScan, Microsoft Forefront, Quick Heal AntiVirus Lite, Symantec Endpoint, and Trustport Antivirus 2009.
