I am with Mdd on this one. Removal is always the least of your problems. Recovery.... well, there are a couple of options you could try.
1. System restore point (To reset your system back to your previous state before infection, provided that you have such restore point)
2. Shadow copies of the files. You could try using Shadow explorer to recover your files manually, that will take quite some time to get through as the process is VERY manual.
Also, there is no decryptor for this malware, at least none that is useful or could in any way help you. Lesson learned for next time, time to back up the files!
