About decrypting = zero chances....

In case you would like to be sure that the system is clean, I would suggest to download and run with administrator privileges from your PC Combofix (save it on your Desktop):

an then also AdwCleaner to clean up your browsers:

After that, you have to perform a Malwarebytes and SuperAntiSpyware full scan:

So we have had ZERO success with doing this.  Cryptowall uses PKI to encrypt the files.  Unless you have a super computer then you have two choices.

Pay the Randsom (It does work)
Recovery from Backup

We have had this happen many times to our clients.  Bad user decisions mostly.  We have recovered from backup on all but one occasion.  My client wanted to pay the ransom.  IT cost them over $700 US dollars by the time it got put into BitCoins and about 24 hours.

As per above, you cannot decrypt the files yourself. You are dealing with criminals, so take GREAT care in paying the ransom. The majority of us in here do not recommend paying the ransom.

Restore from backup and give consideration to formatting and reinstalling Windows on the affected machines to truly clean them up.

Short answer:

No decryption method exists for Cryptowall 3.0

Long answer:

Go here to Bleeping Computer http://www.bleepingcomputer.com/virus-removal/cryptowall-ransomware-information#decrypt and read about Cryptowall.

It is easy enough to remove Cryptowall.  For the client for future reference they need to ensure they have good robust backup procedures and practice safe Internet surfing and mail practices.
