A friends laptop has been hit by CryptoWall 3.0, sorry but I've hacked around a bit on it first before reading your instructions including running combofix.


1) They had no AV installed so I've put free AVG on it


2) Can I get it check to ensure that it won't re-infect/encrypt etc?


3) all of their photos and childs schoolwork have been encrypted and renamed to *.ecc, what are the chances of decryption keys becoming available in the future like with Cryptolocker?


Please see HELP_DECRYPT.HTML below



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: 1.http://7oqnsnzwwnm6zb7y.partypayonion.com/a2ok7d 


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: 7oqnsnzwwnm6zb7y.onion/a2ok7d
4. Follow the instructions on the site.


Your Personal PAGE: http://7oqnsnzwwnm6zb7y.partypayonion.com/a2ok7d

Your personal code (if you open the site (or TOR 's) directly): a2ok7d

Hi there,

It appears that you got hit with a double infection - the .ecc files are from TeslaCrypt, but the ransom note is from CryptoWall 3.0.

Since you have run ComboFix on this machine, please follow the instructions in ==>This Guide<== starting at Step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include a description of your computer issues, what you have done to resolve them, and a link to this topic.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

To remove the infection, please follow the instructions provided by Alexstrasza.

Cryptowall typically deletes (though not always) 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 Decryption of any CryptoWall Files...is impossible since there is no way to retrieve the private key that can be used to decrypt your files without paying the ransom.

There are also lengthy ongoing discussion in these topics:

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. To avoid unnecessary confusion...this topic is closed.
