To date, there is no other method to recover the encrypted files, but only to pay the money to fraudsters. Developers of free Nvetud decryption utilities which can unlock these files are working on creating them, but the result is not yet, and it is not known when it will be.

Never pay the ransom! However, the victim who will pay the ransom to authors of the Nvetud file virus cannot be completely sure of obtaining a special code key, because he is dealing with unscrupulous and dishonest people who are ready to commit any immoral actions, including hiding after receiving the ransom from the victim, and not providing a decryption utility (key) to decrypt locked personal files.

The Nvetud virus is not the only one of its kind, for some of them, there are already ways to restore access to blocked personal files that were designed by experienced security professionals. This gives hope that the Nvetud decryption tool can be created for this crypto malware as well. However, since each case of coding is original, victim should seek help and provide an identifier that will give the opportunity to get the special code key and decryption utility.
