Scary - but at least Microsoft seem to be doing well with their Malicious Software removal tool ...
I note thought the MS AntiSpyware, AdAware, SbyBot Search & Destroy, PestPatrol, Webroot SpySweeper and CounterSpy all came up with no detections at all ... scary ... I use most of those.
NOD32 doesn't come out too bad though ... which is some consolation ...
