The worst thing I ever got hit with was CryptoWall 3.0 ..still have all the encrypted .jpg pics of the family (and videos) around 58GB worth ...Just hope that someday the encryption can be broken.

My own stupid fault eh ...had just put the PC back together again and had installed a new operating system and was surfing without any protection ... I was an easy target ..the fookers wanted £500 for the key to remove the encryption.
