FYI - new Kaspersky Ransomware decryptor software

Kaspersky have recovered the full list of over 14,000 encryption keys used by the criminals responsible for CoinVault and Bitcryptor ransomware. They have now updated their decryptor utility to include all of these keys. This means that if a system has been encrypted and held to ransom using this type of encryption, you should now be able to decrypt your drive! The 'How-to' guide is here.

However, it apparently does not work against CryptoWall 3.0 ransomware.
