I'd like to see the methodology used in the MaximumPC test first but when it included one AV that hasn't been certified by ICSA nor WestCoast labs and highly rank another that doesn't scan HTTP traffic, doesn't have HIPS/behaviour blocker and only update once a day, then it doesn't look good...
There are not that many organizations out there that can test AVs properly, and those that can often are paid by the vendors to test their products, e.g., AV-Comparatives, Virus Bulletin.
Many tests are still based on "static" tests of how many samples are detected by the AV during a "on demand" scan. While signature based detection is a major component of AV and still important for detecting known malware, most of the better AVs nowadays have some form of HIPS or behaviour blocker that can block unknown malware.
Both AV-Comparative and Virus Bulletin have "proactive" tests where they test the ability of AVs to detect malware samples collected during the week *after* the definition database was released. Detection rate usually falls drastically to the <70% range.
There is always a time lag before AV vendors can get signature updates to users -- anywhere from 4-8+ hours, sometimes it can take days -- the AV I use average 5,000 new signatures a day and increasing. So in a real world environment the detection rate from the signature based file scanner will more likely be those <70% rates seen in "proactive" tests rather the >95% rates seen in the "static" tests.
The lower detection rate is not just due to known samples, but also because with most AV the "on-demand" scanner is configured to use the most thorough settings, whereas the "on-access" and HTTP scanners -- the ones that are on the front line in the real world -- are usually configured to be less thorough to minimize impact on performance.
With malware that are missed by signature detection, HIPS and behaviour blockers come into play. Testing organizations have started to run "dynamic" tests:
AV-Comparative
AV-Comparatives - Independent Tests of Anti-Virus Software - Dynamic Test
AV-Test
Maximum Security: 2010 Internet Security Suites - PCWorld
NSS Labs (registration required)
Consumer Anti-Malware*-*nsslabs.com
Personally, nowadays I'm more interested in the performance of non-signature based detection/blocking and other "cloud based" technology than the performance of the classic signature based detection.
