Computer Virus Help Needed

I use Windows pretty much because I have to for a lot of the stuff I do, but all my important stuff is stored on CD or DVD and I consider any Windows installation a throwaway.

Due to the virus the OP ended up with even external storage isn't safe (or even cloud storage in some cases)

That virus makes an encrypted copy and then deletes the original file, so we may be able to recover the deleted unencrypted originals with a program I use just for this.

(Maybe)
