Security publisher Virus Bulletin has posted the results of the latest edition of its VB100 anti-malware tests.
The test pits security vendors against a collection of malware samples targeting Windows XP SP3. It is the first test based on Windows XP since the August 2008 edition.
To earn certification on the test, a security suite is required to accurately detect every sample from a 'wild list' of active malware, and avoid false positive returns on non-malicious samples.
In the April tests, nearly all of the big-name vendors earned certifications, including McAfee, Symantec and Microsoft, while Computer Associates saw its two anti-malware products gain the award after failing the August 2008 Windows XP test.
Among those not making the cut were PC Tools, which saw its Antivirus, Internet Security and Spyware Doctor products fall short of the certification by missing 12 malware samples.
August 2008 certification winners eEye and Norman also failed the test, missing 11 and 10 malware samples respectively.
