"DECRYPT_INSTRUCTION.txt" - Not sure what's going on

3 files (the txt file named in the title, a .html title with the same name, and a shortcut to "download tor") showed up in pretty much every folder in my computer.

 

I did some research and learned that it was related to the CryptoLock virus that started about a year ago. Mine seems a little different though, there's no timer or anything, just those 3 files in every folder.

 

I tried to download "Omni Crypto Finder" to find an encrypted file to give to "https://www.decryptcryptolocker.com/" so they can email the decryption key. But I've had no luck finding an encrypted file.

 

Every program still works, but some with limited functionality: almost all previous word files are "corrupt", new ones don't allow header, iTunes shows a library but won't play anything, etc... Other programs are totally untouched. 

 

Now, since I can't find any encrypted files, don't have any backups/shadow copies/restore points, and the problems persist, I'm confused. I'm not sure what to do.

 

I think that I may have a virus related, but different, to cryptolock. And the Omni-finder and the website won't be able to help because of it.

 

Any ideas? Thanks in advance.

A repository of all current knowledge regarding CryptoWall & CryptoWall 2.0 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 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.

CryptoWall 2.0 uses its own TOR gateways...see Updated CryptoWall 2.0 ransomware released that makes it harder to recover files.

There is also a lengthy ongoing discussion in this topic: CryptoWall - new variant of CryptoDefense as noted by Crazy Cat.

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
