A third of 60 anti-malware products for Windows XP failed to make the grade
in independent security tests.
20 out of 60 security products tested by independent security certification
body Virus Bulletin flunked its rigourous VB100 certification, mainly because of
false positive problems. False alarms in scanning benign files from major
providers including Adobe, Microsoft, Google and Sun tripped up many of the
products under test. Failure to detect complex polymorphic viruses also acted as
a stumbling block during Virus Bulletin's largest ever test of anti-malware
products to date.
