How to decrypt CryptoWall
 

What does this mean ?
This means that the structure and data within your files have been irrevocably changed, you will not be able to work with them, read them or see them,it is the same thing as losing them forever, but with our help, you can restore them.
How did this happen ?
Especially for you, on our server was generated the secret key pair RSA-2048 - public and private.
All your files were encrypted with the public key, which has been transferred to your computer via the Internet.
Decrypting of your files is only possible with the help of the private key and decrypt program, which is on our secret server.

Not sure there is any practical way to decrypt it. Once infected and the infection has done it's damage, you're basically stuffed.

In my opinion, the people involved in this particular activity should be totally and irrevocably removed from society.

Did you try with:

h***s://www.decryptcryptolocker.com/

it's working on old cryptolocker, maybe it can work with your version.

Also h***s://noransom.kaspersky.com/ has just been relased.

The noransom.kaspersky.com decryptor works only for the CoinVault ransomware and that too not in all the instances. Like mentioned, invest in a good antivirus once you've got rid of the piece of crap. People who write such stuff should be punished severely.

I'm sure you might have searched, but just some more tips:

But cracking the encryption is next to impossible because of the RSA 2048 bit keys. It is the backbone that is keeping all world's the Certificate Ecosystem alive and protecting all the financial transactions across the globe with the help of TLS/SSL!
