AV-Test.org, based in Magdeburg, Germany, has just released results of an exhaustive malware-detection test. They threw over 600,000 malware samples at thirty-odd antivirus programs and measured how many each product detected. That's just detection - there was no effort in this test to measure whether the products could clean up the malware they found. The only real surprise to me is how well the best products did; quite a few reached 98% or even 99% detection.
The samples shook out into four distinct categories - Trojans, worms, backdoors, and bots (zombies). Only Windows-based threats were used, and only current threats (meaning they're no older than 12 months). Overall, the products were most successful at detecting worms and bots. The range of ability in detecting Trojans was quite a bit wider.
Limiting the list to products that we've reviewed in PC Magazine, the top scorer was Avira's Antivir, with 99% detection overall. F-Secure, Symantec, and Kaspersky all came close with 98% detection. Avast!, AVG, and BitDefender weren't far behind at 96%. From that point, though, scores start to trail off. Panda got 92%, Trend Micro got 91%, NOD32 88% and McAfee 87%. Microsoft's OneCare didn't come in dead last, as it did in an earlier test, but it only detected 81% of the threats.
Grisoft's Ewido Anti-spyware didn't do so well, detecting only 75% - but then, it's strictly an anti-spyware product, not an antivirus. As noted, AVG (also from Grisoft) scored 96%. VirusBuster, sold both as a standalone product and as the licensed antivirus in Agnitum's new security suite, only detected 73%. And bringing up the rear, Computer Associates eTrust-VET antivirus detected just 62%.
That's quite a range! And it would surely be a still greater spread if AV-Test had gone on to analyze how well the products removed what they detected. How well did your antivirus do?
