BitDefender, who make an internet security product, have recently released a faulty update that marks legitimate Windows and BitDefender files as malicious. BitDefender will then quarantine these files identifying them as “Trojan.FakeAlert.5″ resulting in Windows becoming un-bootable.
This faulty update only effects the 64-bit versions of Windows and BitDefender had to have updated itself between the times of 8am and 11:30am on the 20th of March. BitDefender have released a press release containing fixes for the various versions located here.
