It is called the Crypto Virus and it encrypts all of the files on your computer and demands you pay a ransom, usually in bit coins, to get the key to unlock them.

If you backed your files up, you could restore them. With your documents stored locally on a Windows machine or server, this is your only hope.

Setup properly for document storage, working files would stay safe and machines would be free of viruses.
