Our home computer was infected by this Malware.  We have received the standard ransom demands that have been discussed with this criminal activity.  The extensions on these files is .dofmtjg.  Is that a new extension or an older variant? 


Obviously I would like to get back the files (mainly the pictures) that are damaged.  Is there any way short of paying a ransom to recover the files.  The machine is becoming very unresponsive since all of this began. 


Also, this is part of the TOR activity that I have read about.  It mentioned that in the notice I received after I ran a scan.


I am not a PC expert, so I apologize if I have described this incorrectly. 


Thank you.

A repository of all current knowledge regarding CTB Locker and Critroni Ransomware is provided by Grinler (aka Lawrence Abrams), in this tutorial: CTB Locker and Critroni Ransomware Information Guide and FAQ

Reading that Guide will help you understand what CTB Locker (Critroni) does and provide information for how to deal with it. Also see New Critroni variant offers free test decryption and now uses CTB2 extension. Unfortunately, there is still no known method of decrypting your files without paying the ransom.

There is also an ongoing discussion in this topic: CTB Locker or DecryptAllFiles.txt Encrypting Ransomware. 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.
