I came home from vacation and got on yahoo. Not much else actually. Computer was a bit slow and sounded like it was downloading so I ran Spybot and found regestry keys and fixed them. Rebooted and ran it again with the same registry key issue. Something about windows security.

 

I ran msconfig and noticed a hh.exe that isn't usually there and did some research on it. Seems legit, but I unchecked it and rebooted. Checked it again and it was back. I repeated the process. When it came back I had the CBT-Locker on my desktop with a countdown timer saying ti had locked my files unless I pay the ransom.

 

Being a bit illeterate on computers my search on fixing it is a bit daunting since I don't understand what it was talking about. I did download malwarebytes and run a scan fixing a number of issues. Ran it again and it was fine. Files are still locked of course and the desktop still shows the CBT-Locker background.

 

That is all I have done to this point. I came here for help right away.

 

Update: I changed my background, but it still shows up when I log off the computer for just a moment. I also downloaded and removed spyhunter. I could not afford to pay to have it remove the rootkit and other things it found.

 

I am running XP

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.

Thanks
