Hi all!

 

i am working on a friend's desktop that has a Cryptowall 3.0 infection (popup requests, files encrypted, etc.).  Please let me know where to start in getting rid of this malware.  I have made some progress by getting a decent AV program and Malwarebytes Pro installed, but the malware is still there.  

 

Thanks in advance...

Kim

Oh, and I was able to use restore previous version in folder options to get his files back...so there's some good news!

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.

Thanks
