The original CryptoLocker Ransomware which first appeared in the beginning of September 2013...does not exist anymore and hasn't since June 2014. There are several copycat and fake ransomware variants which use the CryptoLocker name but those infections are not the same. Any references to CryptoLocker and retrieving keys for it will not work anymore. BloodDolly's TeslaDecoder is for TeslaCrypt/Alpha Crypt ransomware.

Are there any file extensions appended to your files...such as .ecc, .ezz, .exx, .zzz, .xyz, .aaa, .abc, .ccc, .vvv, .CTBL, .CTB2, .crinf, .XTBL, .encrypted, .crypt, .pzdc, .good, .EnCiPhErEd, {CRYPTENDBLACKDC}, .vault, .HA3, .toxcrypt or 6-7 length extension consisting of random characters?

Did you find any ransom note? These infections are created to alert victims that their data has been encrypted and demand a ransom payment. Check your documents folder for an image the malware typically uses for the background note. Check the C:\ProgramData (or C:\Documents and Settings\All Users\Application Data) for a randomly named .html, .txt, .png, .bmp, .url file.

These are some examples:
HELP_DECRYPT.TXT, HELP_YOUR_FILES.TXT, HELP_TO_DECRYPT_YOUR_FILES.txt
HELP_RESTORE_FILES.txt, HELP_TO_SAVE_FILES.txt, RECOVERY_KEY.txt, DecryptAllFiles.txt
DECRYPT_INSTRUCTIONS.TXT, DECRYPT_INSTRUCTION.TXT, HOW_TO_DECRYPT_FILES.txt
How_To_Recover_Files.txt, ReadDecryptFilesHere.txt, Help_Decrypt.txt, About_Files.txt
RECOVERY_FILES.txt, DecryptAllFiles_<user name>.txt, encryptor_raas_readme_liesmich.txt
HOWTO_RESTORE_FILES_*****.txt, DecryptAllFiles_*******.txt (where * are 6-7 random characters)
RECOVERY_FILE_*****.txt, restore_files_*****.txt (where * are random characters)
howto_recover_file_*****.txt, _how_recover_*****.txt (where * are random characters)
how_recover+***.txt, recover_file_*****.txt, (where * are random characters)
Once you have identified which particular ransomware you are dealing with, I can direct you to the appropriate discussion topic for further assistance.

YES I HAVE ,IT IS A TEXT FILE  I WILL ATTACH IT

 

 

What happened to your files ?

All of your files were protected by a strong encryption with RSA-4096.
More information about the encryption keys using RSA-4096 can be found here: http://en.wikipedia.org/wiki/RSA_(cryptosystem)
 
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.
 
111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111
How did this happen ?
---Specially for your PC was generated personal RSA-4096 KEY, both public and private.
---ALL YOUR FILES were encrypted with the public key, which has been transferred to your computer via the Internet.
111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111
Decrypting of your files is only possible with the help of the private key and decrypt program, which is on our secret server.
 
What do I do ?
So, there are two ways you can choose: wait for a miracle and get your price doubled, or start obtaining BTC NOW, and restore your data easy way.
If You have really valuable data, you better not waste your time, because there is no other way to get your files, except make a payment.
 
For more specific instructions, please visit your personal home page, there are a few different addresses pointing to your page below:
 
If for some reasons the addresses are not available, follow these steps:
1. Download and install tor-browser: http://www.torproject.org/projects/torbrowser.html.en 
2. After a successful installation, run the browser and wait for initialization.
3. Type in the address bar: vr6g2curb2kcidou.onion/AF3EEB51EDA4C4

What is the exact name of the above .txt file?
Are there any file extensions appended to your files such as those noted above or something else?

You are dealing with a newer variant of TeslaCrypt/Alpha Crypt. TeslaCrypt includes several known versions with various extensions for encrypted files to include: .ecc, .ezz, .exx, .zzz, .xyz, .aaa, .abc, .ccc., .vvv...as described here. Some of the new variants are disguised as CryptoWall.

Any files that are encrypted with the newer variant of TeslaCrypt will have the .exx, .xyz, .zzz, .aaa, .abc, .ccc or .vvv extension appended to the end of the filename. The .aaa/.abc/.ccc/.vvv variants leave .html, .txt, files (ransom notes) with names like RECOVERY_FILE_*****.txt, restore_files_*****.txt, recover_file_*****.txt, Howto_RESTORE_FILES_*****.txt, howto_recover_file_*****.txt, _how_recover_*****.txt, how_recover+***.txt (where * are random characters).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:Since v5 there is no way to decrypt the newer TeslaCrypt variants (.xyz, .zzz, .aaa, .abc, .ccc, .vvv) without Tesla's private key or a purchased decryption key. It is no longer possible to get the encryption key from Tesla's request without Tesla's private key...since there is no private key anymore, it can't be used to decrypt files. See here for possible decryption information with each version.

There is an ongoing discussion in this topic where you can ask questions and seek further assistance.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
