    What do we do if I have no original files left? I have no unencrypted original files that are the same as the encrypted ones to drag onto the decryptor.

    What if the virus was so smart that it only encrypted just a couple of my documents, while leaving the others untouched? For example none of my photos are encrypted. How can I still get my files back? (I really need them)
