We're in the throes of getting rid of crappy old McAfee, so I wanted to give all of the servers and what not a once over before we install Forefront.

I ran this on the servers and it identified quite a few dormant bits and pieces that McAfee never noticed.

And it's free. Boot into safe mode, install, run, disinfect (or clean) and when you quit it uninstalls.

And it's FREE.

Kaspersky Virus Removal Tool 2010

I'd be interested to hear if it finds anything your normal AV didn't pick up.
