A Website called ConsumerReports.org today published an article (strangely it was dated “September 2006) about a test they conducted involving 5,500 samples of artificially created virus samples.

There are several things here that do not seem right:

  1. It is claimed that created viruses were “the kind you’d most likely encounter in real life” which is, of course, something the testers cannot know.
  2. Creating new viruses for the purpose of testing and education is generally not considered a good idea - viruses can leak and cause real trouble (you can read an open letter on the AVIEN site about that).
  3. There is a more scientific way of measuring real proactive detection of AV products on future malware - it is called “proactive testing” or “retrospective testing”. The idea is to measure, say, 3-month old AV product against real field viruses that appeared within these last 3 months. The discussion of the methodology of such tests can be found here and some real test results with common AV products are on the AV-comparatives.org site.
  4. Objection #1, that ConsumerReports.org cannot know what viruses we are going to face in future could be moot as their testing team apparently invented a time machine and shifted themselves forward to September ;-) .
