Recover files encrypted by the .492 ransomware Ransomware.

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. However, 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:

  • Emsisoft.
  • TrendMicro.

So you may have a chance of restoring some of your files with this method. Here are several data recovery programs which you can try and restore at least some of your files:
