Firstly thank you for looking at this post. 

 

I have a windows XP sp3 system that yesterday became infected with cryptowall 3.0

 

It used group policys to lock out AVG and MBAM from running, and then went nuts throughout the system. 

 

I used ESET Online scanner, mbam, mbar and avg on the system. 

 

currently it is mostly stable, except for a 2nd explorer.exe that spawns and initiates outgoing connections to the web.

 

I used process hacker to watch what was going on and to suspend the process. If I kill it, it respawns fairly quickly, and says it was spawned by the true explorer.exe process.

 

 

I have done an sfc /scannow , netsh winsock reset , reinstalled sp3. all to no avail.

 

please advise if you can :)

A repository of all current knowledge regarding CryptoWall, CryptoWall 2.0 & CryptoWall 3.0 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 & CryptoWall 2.0 does and provide information for how to deal with it and possibly decrypt/recover your files. 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 no way to retrieve the private key that can be used to decrypt your files without paying the ransom.

CryptoWall 3.0 uses its new TOR gateways and has an extended deadline to pay the ransome...
see After a brief hiatus malware developers release CryptoWall 3.0.

There is also a lengthy ongoing discussion in this topic: CryptoWall - new variant of CryptoDefense Support & Discussion Topic.

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
