Method 2: If you try to decrypt your files using third-party decryption tools. There are many antivirus providers who have decrypted multiple ransomware viruses the last couple of years and posted decryptors for them. Chances are if your ransomware virus uses the same encryption code used by a decryptable virus, you may get the files back. Echter, this is also not a guarantee, so you might want to try this method with copies of the original encrypted files, because if a third-party program tampers with their encrypted structure, they may be damaged permanently. Here are the vendors to look for:
