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.
A representative from BitDefender noticed this blog post here on Technibble and responded with the following:

Seems like a pretty big screw up. I’m almost surprised this kind of thing doesn’t happen more often, though.
i’ll stick to SEP

This seems like it would be great for your PR.
This actually happened to me on Saturday. I hopped on my computer that morning and all of a sudden I started getting these virus alerts and BD was deleting my system files. I quickly did a system restore and uninstalled BD. This was a major screw up on their part
@ Denell we are very sorry about your issues and we want to assure you that is was an isolated situation.
