Essentially somewhere in the last couple of days, i couldn't open a saved word document and noticed three other documents that I have not seen before. 
Below is some vital information that may assist in troubleshooting this problem. 
 
- I am currently usings windows 7.
- virus has spread thoughout nearly all my word documents, pdfs, pictures and now media (songs & vidoes).
- virus is similar to cypto locker type viruses as it requires payment for decryption but is referred to as CryptoWall.
- It has encrypted all my files (mentioned above and not .exe & internet works fine) and leaves behind the following 3 documents if every folder: 
-DECRYPT_INSTRUCTION  Chrome HTML Document (.HTML)
-DECRYPT_INSTRUCTION  txt. doc
-DECRYPT_INSTRUCTION  internet shorcut
 
- I have tried hitman pro, anit-malwarebytes and avg (even in windows safe mode) to get rid of it but all have failed to detect the virus.
 
 
 
 
 
 
- The text document contains the following information and the links lead to a page where the the creator of the virus demands payment:
 
 
 
 
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:
 
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: kpai7ycr7jxqkilp.onion/3otN
4.Follow the instructions on the site.
 
 
IMPORTANT INFORMATION:
Your personal page (using TOR): kpai7ycr7jxqkilp.onion/3otN
Your personal identification number (if you open the site (or TOR 's) directly): 3otN
 
 
 
 
 
Please help me get rid of this virus, any help at all is highly appreciated.

Hello -

As a brief answer, if you are not sure of the exact details of the infection version, please read on -

 

Grinler (aka Lawrence Abrams), the site owner of BleepingComputer, has also created this tutorial:
CryptoLocker Ransomware Information Guide and FAQ

There is a lengthy ongoing discussion in this topic: Cryptolocker Hijack program.
All are welcome to post, add their ideas, and hope to find solutions ........

Since this infection is so widespread, rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions or comments in that thread.
Also see this topic at Malwarebytes Forum

Variants :
There is a lengthy ongoing discussion in this topic: CryptoDefense - Newest cryptolocker variant.
Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions or comments in that topic discussion.
 
Sorry if the reply sounds a bit "negative" but we are working on more solutions every day -
I do hope you understand, as this is a world wide problem that I have followed since September last year.

- virus is similar to cypto locker type viruses as it requires payment for decryption but is referred to as CryptoWall.

CryptoWall is CryptoDefense rebranded with a new name.

There is also a lengthy ongoing discussion in this topic: New Crypto variant? CryptoWall...CryptoDefense with a new name.

As I indicated there is 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.

The same applies if you are referring to Cryptolocker or CryptoDefense...noknojon provided links for those discussion topics.

Thanks

:welcome: to Bleeping Computer.

I believe you are referring to New PClock CryptoLocker Ransomware.

If so, then Support and Discussion is available in that topic.
