Windows 64 users have their files quarantined and computers shut down

The latest update to BitDefender, the respected anti-virus program, is flagging legitimate files as infected. Then it quarantines them.

The problem is those files are system files and BitDefender itself. The company acknowledged the problem after users flooded its website with complaints.

Due to a recent update for Windows 64-bit systems it is possible that BitDefender detects several Windows and BitDefender files as infected with Trojan.FakeAlert.5 .

Following this event, in some instances BitDefender and/or Windows did not work properly anymore (PC failed to boot or certain applications did not work anymore )
