I downloaded different things. I think a program i dowloaded to attach subtitles is what infected the computer, it had a bunch of other things that unpacked with it. I ran Malwarebytes and it keeps removing things but i'm still infected. I have a data stick that is infected too. I have a screenshot of the ransom note. I assume all is lost on the computer and the data stick. I don't have any of the software to restore the system with and i don't have any System Restore dates saved on my computer. I can't get the computer to start in SafeMode, it just freezes while it is loading.


Can i save the files? Can i save the computer? Can i use it now to make new files or will anything on the computer instantly be infected? If i plug an external hard drive into my computer will it get infected too?

:welcome: to Bleeping Computer.

A repository of all current knowledge regarding CryptoWall, CryptoWall 2.0 & CryptoWall 3.0 is provided by Grinler (aka Lawrence Abrams), in this topic: CryptoWall and DECRYPT_INSTRUCTION Ransomware Information Guide and FAQ

Reading that Guide will help you understand what CryptoWall (including versions 2.0 & 3.0) does and provide information for how to deal with it. Cryptowall typically deletes 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 one of those topic discussion.
