A number of BitDefender users, whose 64-bit Windows systems stopped working or were unable to be rebooted after security program updates, vented their frustration by flooding the antivirus vendor's forum pages over the weekend.

According to an IDG report, users on forum boards started signaling the problem on Saturday evening. The complainants said several Windows files, as well as the security vendor's own program files, were identified as "Trojan.FakeAlert.5" malware after they performed an update for their BitDefender antivirus programs.

In an e-mail update Monday to ZDNet Asia, Vitor Souza, BitDefender's global communications director, explained that "multiple" BitDefender and Windows files which comprise .exe, .dll and other binary files, were incorrectly detected as malware and "moved to quarantine."
