The only time anyone within my family got an infection was when our grandfather wanted to stream a 1960's television show. He ended up downloading a spam pushing virus instead of the "HD Show Player". What were you doing OP?
In serious discussion I also had a friend who downloaded what he assumed was a bootleg movie from a shady torrent site, which he now knows is a big scam, and had a similar infection to yours. The only difference was it was an older version of the virus/malware. When he googled it he found it contained one fatal flaw. The decryption key was stored on the harddrive it infected in a very obvious file. The creators of this virus have updated it since to store the decryption key on their own server. Make sure the virus you had was not one of these old models.
Edit: From what I am reading with what you posted you might have gotten version 2.0 which is the newer killer. No way to beat it yet as it had its own bug fixes. Best case is for people to learn to save all their precious files onto flash drives (64GB are under $30 now which can store many videos, pictures, and other files), cloud drives, or portable hard drives. Personally I would choose flash drives for things you will access often with a good read/write speed followed by cloud storage which you can find fairly cheap if not free these days although you never know who is reading your files. I would not suggest portable hard drives as many brands are iffy and might stop working one morning for no reason or if you pull the usb cable out before it finishes a transfer.
