Dears,

I have lost my documents on my PC, I can not open any word file, each folder contains picture which tell me that 

What happened to your files ?
All of your files were protected by a strong encryption with RSA-2048 using CryptoWall 3.0.
More information about the encryption keys using RSA-2048 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.
 
 
How did this happen ?
Especially for you, on our server was generated the secret key pair RSA-2048 - public and private.
All your files were encrypted with the public key, which has been transferred to your computer via the Internet.
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 ?
Alas, if you do not take the necessary measures for the specified time then the conditions for obtaining the private key will be changed.
If you really value your data, then we suggest you do not waste valuable time searching for other solutions because they do not exist.
 
 
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:
2.After a successful installation, run the browser and wait for initialization.
3.Type in the address bar: paytoc4gtpn5czl2.onion/x9mk5h
4.Follow the instructions on the site.
 
 
IMPORTANT INFORMATION:
Your personal page (using TOR): paytoc4gtpn5czl2.onion/x9mk5h
Your personal identification number (if you open the site (or TOR 's) directly): x9mk5h
 
So please if any one can help me, tell me what should I do?
or if any one can restore the attached file tell me how can I restore the other files

Attached Files

Hi mbj1992-
 

So please if any one can help me, tell me what should I do?
or if any one can restore the attached file tell me how can I restore the other files

Your computer can be cleaned of the infection but due to the strength of the encryption algorithm you only have a partial chance of recovering encrypted files.  The only method you have of restoring your files is from a backup, with file recovery tools, or if your lucky from Shadow Volume Copies.
 
If you would like help cleaning your system and with attempted file recovery you will need to follow the prep guide and post in the forum linked to below as this is a complicated infection and requires elevated help.
 
Good Luck   :)
 
This is the prep guide to follow before posting:  http://www.bleepingcomputer.com/forums/t/34773/preparation-guide-for-use-before-using-malware-removal-tools-and-requesting-help/

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.

If you just need help with cleaning out the infection, then follow the instructions provided by Johnny Computer above.

If you have other questions or concerns...there is 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
