Errata: Windows NT comparative review

Posted by   Virus Bulletin on   Feb 28, 2004

After re-testing, Alwil's AVAST! product gains a VB 100% award.

The results were reviewed for two products in the Windows NT comparative review (VB February 2004, p.12), with the following outcome:

Alwil AVAST!

After consultation with the developers a method was discovered by which the on-access function of AVAST! could be tested fully. The results of this re-testing were such that Alwil's product gains a VB 100% award.

Sophos Anti-Virus

Sophos Anti-Virus was noted in the Windows NT comparative as having missed one sample in the polymorphic test set. Further investigation determined that although this file was triply infected with W32/Zmist.D, the multiple infection had rendered the sample unable to replicate. Consequently this file has been removed from the test set. Although this does not affect percentages for other products, this does mean that Sophos Anti-Virus achieved 100% detection in the polymorphic test set, and indeed across all test sets.
