Yesterday I found that I could not open any of my files. I then noticed a couple of new icons on my desktop that made me realized I had been infected. Here is the note:

What happened to your files ?
All of your files were protected by a strong encryption with RSA-2048 using CryptoWall.
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.https://kpai7ycr7jxqkilp.enter2tor.com/9af9
2.https://kpai7ycr7jxqkilp.tor2web.org/9af9
3.https://kpai7ycr7jxqkilp.onion.to/9af9
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: kpai7ycr7jxqkilp.onion/9af9
4.Follow the instructions on the site.
IMPORTANT INFORMATION:
Your personal page: https://kpai7ycr7jxqkilp.enter2tor.com/9af9
Your personal page (using TOR): kpai7ycr7jxqkilp.onion/9af9
Your personal identification number (if you open the site (or TOR 's) directly): 9af9

Is there any hope for restoring my files?

CryptoWall is essentially a new variant of CryptoDefense.

A repository of all current knowledge regarding CryptoDefense is provided by Grinler (aka Lawrence Abrams), in this tutorial: CryptoDefense and How_Decrypt Ransomware Information Guide and FAQ

Reading that Guide will help you understand what CryptoDefense does and provide information for how to deal with it and possibly decrypt/recover your files. At this time there is no fix tool for CryptoWall.

There is also a lengthy ongoing discussion in this topic: CryptoWall - new variant of CryptoDefense. 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
