how to open up encrypted files

A customer brought in this computer that, when it opens up to the desktop screen, the system will stop running and a message came up saying that all the files are encrypted and it gives a link to go to and for a fee the customer could have the encryption removed.  However, the link is invalid and since that system was unusable, I backed up the files, wiped the drive clean and re-installed that OS.  Now all of his files have .jthdooc at the end of each file and if I remove that extension, the file will open up but is all garbled.  
Any help on this issue would be greatly appreciated.

Hi,

This looks like the cryptowar virus, if the customer didn't have backup prior to the encryption there isn't much you can do, these files need a private key to be decrypted so without backup the datas are probably lost.

The data is rubbished. Forget about it. This is a work done by a virus as correctly noted above.

The files needed for recovery will have been destroyed along with the OS - they are now beyond recovery, sorry.

Advise to your customer that daily or weekly backup nowadays is a must have.

Take care
