You are most likely dealing with a newer variant of TeslaCrypt/Alpha Crypt.

Any files that are encrypted with the newer variant of TeslaCrypt will have the .exx, .xyz, .zzz, .aaa, .abc or .ccc extension appended to the end of the filename. The .aaa/.abc variant drops files (ransom notes) with names like Recovery_File_*****.html, Recovery_File_*****.txt, restore_files_*****.html, restore_files_*****.txt, HOWTO_RESTORE_FILES_*****.txt, (where ***** are random characters) and pretends to be CryptoWall 3.0.

A repository of all current knowledge regarding TeslaCrypt, Alpha Crypt and newer variants is provided by Grinler (aka Lawrence Abrams), in this topic: TeslaCrypt and Alpha Crypt Ransomware Information Guide and FAQ

Information about and support for decrypting files affected by Alpha Crypt & TeslaCrypt ransomware can be found in this topic:
TeslaDecoder released to decrypt .EXX, .EZZ, .ECC files encrypted by TeslaCrypt

Unfortunately there is no way to decrypt the newer TeslaCrypt variants (.xyz, .zzz, .aaa, .abc, .ccc) without Tesla's private key.

From the above topic...

Unfortunately there is no solution for .ccc variant of TeslaCrypt. This variant can be decrypted only by their private key except your randomly generated and never stored private key.

...ccc and abc variants are very similiar and can't be decrypted without Tesla's private key, your generated private key or private keys used for file encryption.

BloodDolly, Post #136

The only other alternative is to save your data as is and wait for a possible breakthrough...meaning, what seems like an impossibility at the moment (decryption of your data), there is always hope someday there may be a possible solution so save the encrypted data and wait until that time.

There is an ongoing discussion in this 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. Doing that will also ensure you receive proper assistance from our crypto malware experts since they may not see this thread. To avoid unnecessary confusion...this topic is closed.

Thanks
