BitDefender 2010 Update Problem

by Scott Fendley (Version: 2) 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.

Update: BitDefender has been sharing more information about this incident involving 64-bit architecture via their twitter account. They point users to their knowledge base for more details on how to recover from this problem. I hope that beyond the initial response of this major issue, BitDefender and all antivirus vendors will recheck how they test, do quality assurance, and prepare to use social media as a communication tool for their customers in the case of an emergency
