...the glitch appears to be caused when older VirusScan engines install DAT
5664, which McAfee seems to have pushed out in the past 24 hours. Affected
systems then begin identifying a wide variety of legitimate - and frequently
crucial - system files as malware. Files belonging to Microsoft Internet
Explorer, drivers for Compaq computers, and even the McAfee-associated
McScript.exe were being identified as a trojan called PWS!hv.aq, according
to the posts and interviews.
