We have started to receive reports this morning concerning a popular consumer antivirus product has caused some grief today. BitDefender 2010 appears to have released a set of bad definitions. Unfortunately, these bad virus definitions appear to detect core DLL files and even parts of BitDefender, itself, as infected by "Trojan.FakeAlert.5". There is quite a thread discussing this issue on the BitDefender Forums.
If you or your organization uses BitDefender, I would heavily recommend that you disable auto-update of the definitions until corrected ones are released soon. Also, I would recommend preparing to do a lot of hands-on clean up to reverse those files which were quarantined by accident.
