Virus Bulletin threw the programs in a ring with around 3,000 unique samples of malware spread across four categories: Polymorphic viruses, Trojans, WildList viruses and Worms/bots. Of the 35 tested, only 23 passed, meaning about a third of the products fell to the tests. Among the more known solutions is Symantec's Endpoint Protection, which missed two infections on the Wildlist.
Symantec was quick to defend itself in response to Ars Technicia's original coverage of the Virus Bulletin tests. A company spokesperson said that "In the past ten years, Symantec has earned 44 consecutive VB100 awards, something no other vendor has come close to matching." They went on to add that the missed malware is an "extremely rare replicant of a highly polymorphic file infecting virus" and that they have since fixed the issue in their signatures.
