Ditto. What good is an anti-virus package if a virus is able to neutralize it? I have yet to see McAfee disabled by a virus.
Oh, and then there are the countless install/uninstall issues with Norton that really compound my frustration with their most recent editions of the anti-virus software.
Don't forget another decent anti-virus package offered by Panda Software. I have used their free online virus checker countless times to rescue customers.
