Cryptolocker. Shit is super serious. It's been out for a while but I have a feeling this thing is going to gain steam and do some serious damage. It encrypts all files on or attached to your computer and demands a ransom for the decrypt key. That's right - even an attached NAS or USB drive or portable HDD that is attached to your computer will be encrypted. That means backups too. I suggest you edumacate yourselves about this nasty malware and at the least run this... http://www.foolishit.com/posts/cryptolocker-prevention/\ Mac users are safe for now.
