Hi, ,my files in the usb stick are also encrypted by cryptolocker and demanding $500 to decrypt them. Below is the ransom note found in the AppData folder:

 

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://paytoc4gtpn5czl2.torforall.com/14zk2a5
2.http://paytoc4gtpn5czl2.torman2.com/14zk2a5
3.http://paytoc4gtpn5czl2.torwoman.com/14zk2a5
4.http://paytoc4gtpn5czl2.torroadsters.com/14zk2a5

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: paytoc4gtpn5czl2.onion/14zk2a5
4.Follow the instructions on the site.

 

I have also found an RSA key saved in one of the system folder. I have tried to decrypt the files by using Nathan's CryptoUnlockerGUI.exe software, the files are processed and none of files are decrypted. Please assist me on this.

How is the ransom note named?

These are some examples.
HELP_DECRYPT.TXT, HELP_DECRYPT.HTML, HELP_DECRYPT.URL, HELP_DECRYPT.PNG
HELP_TO_DECRYPT_YOUR_FILES.bmp, HELP_TO_DECRYPT_YOUR_FILES.txt, HELP_RESTORE_FILES.txt
HELP_TO_SAVE_FILES.txt, HELP_TO_SAVE_FILES.bmp, RECOVERY_KEY.txt
DECRYPT_INSTRUCTION.TXT, DECRYPT_INSTRUCTION.HTML, DECRYPT_INSTRUCTION.URL

Are there any file extensions appended to your files...such as .ecc, .ezz, .exx, .CTBL, .CTB2, .XTBL, .encrypted, .vault, .HA3 or 6-7 length extension consisting of random characters?
