Anyone know how many viruses Avast can detect? I think the Avast staff should include that info in their website to the public. For example, Norton and McAfee can detect over 65000

This was discussed a lot in the past…

  1. There are a marketing issue involved. Companies estimate the number of viruses by high.
  2. There are different counts possible: variants, etc.
  3. There is not an international rule for virus naming, so same virus could be consider one or more by other company.
  4. Scanning settings are very important.
  5. Active viruses (ITW) are really more important then the whole number.

Well, etc. etc.

Plus generic signatures and heuristic detections (mail scanner) cannot be really counted.
