Report Help decrypt qmak ransom virus Offline in Help, my files are encrypted! Posted November 17 Hello Ferchich, The file you submitted was encrypted with an online encryption key. Refer back to the link ShadowPuterDud gave you, please. To summarize, an online ID is impossible to decrypt with current technology. An offline ID is decryptable if any one victim with the same ID pays for the encryption key and reports it to us, so we can add it to our decrypter. You can try deleted file recovery software such as Revo from Piriform to see if you can recover older copies of some files, but this does not usually work well. With larger files such as movies or music, sometimes the files will still work if you just change the filenames back to original, since STOP(Djvu) only encrypts the first part of each file. There will of course still be part of the file that is encrypted and effectively corrupt.
