My guess is that your files are gone for good if the time limit has expired and you haven't paid the ransom, which is generally not recommended as you might not receive a decryption key.  If you have a recent backup of your files, then you will be in good shape ONLY after you have successfully removed Cryptowall from your computer.  You should post in an appropriate malware removal forum for assistance.  After the infection is removed, you could restore your data files from your backup.  In future, ensure that you have good anti-virus and anti-malware programs installed with real-time protection and practice safe computing to avoid future infections.

 

Hope this helps.  Have a great day.

There is no decryption method for CryptoWall 3.0 aside from paying the ransom and hoping to receive a functioning decryption utility.  This, as the above poster has stated, is not recommended.

 

You may attempt to restore your files using the methods listed in the CryptoWall 3.0 guide posted on this site, just in case the ransomware did not function properly and failed to delete all Shadow Volume Copies, for example.  This guide can be found here:  http://www.bleepingcomputer.com/virus-removal/cryptowall-ransomware-information

 

As the above poster stated, removing the infection should be the first step prior to exploring file recovery options.

A repository of all current knowledge regarding CryptoWall, CryptoWall 2.0 & CryptoWall 3.0 is provided by Grinler (aka Lawrence Abrams), in this tutorial: CryptoWall and DECRYPT_INSTRUCTION Ransomware Information Guide and FAQ

Reading that Guide will help you understand what CryptoWall & CryptoWall 2.0 does and provide information for how to deal with it and possibly decrypt/recover your files. Cryptowall typically deletes all Shadow Volume Copies with vssadmin.exe so that you cannot restore your files via System Restore or using a program like Shadow Explorer...but it never hurts to try. At this time there is no fix tool and no way to retrieve the private key that can be used to decrypt your files without paying the ransom.

There is also a lengthy ongoing discussion in this topic: CryptoWall - new variant of CryptoDefense Support & Discussion Topic.

Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions, comments or requests for assistance in that topic discussion.

Thanks
