Erratum: Windows XP comparative review: McAfee VirusScan
After re-testing, McAfee's VirusScan product gains a VB 100% award.
Unfortunately an error occurred in Virus Bulletin's Windows
XP comparative review (see VB June 2002, p.21): the
results for Network Associates' McAfee VirusScan were
replaced by those for NAI VirusScan. The correct results for
McAfee VirusScan are reproduced in the table below.
The samples missed by VirusScan were mainly in the
polymorphic set, where the offending items were Sepultura,
W32/CTX and W32/Fosforo. The .TMP file dropped by
W32/Nimda.A was undetected both in the XP review and in
this month's NetWare tests. The file is included in the
standard set as something of a curiosity file since, although
it contains Nimda's code and is dropped by Nimda, this file
is not a threat under any normal circumstances.
The results reported in the review for clean set
scanning and false positives were correct. In
light of the fact that no false positives were
encountered and all In the Wild scans resulted
in full detection, McAfee VirusScan is rightfully
awarded a VB 100 % award for its performance. VB offers
its apologies to Network Associates and to readers for
the confusion.

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.
