Errata: Windows NT comparative review
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.

As expected, the annual VB100 test on Windows XP was an epic. A higher than usual pass rate was tempered by numerous stability issues with the products under test, prompting the unveiling of a new stability rating system. John Hawes has all the details.
