Has anyone seen this variant of malware? It seems to be encrypting the files, as they are corrupt now. It is renaming all files with an extension of .wityymc.


We have the latest updated Vipre Business Premium antivirus on it, as well as CryptoPrevent. Initial scans are showing nothing. MalwareBytes hasnt had a chance to run on it yet.


Anyone seen this or know what it is?

You have a Cryptowall on system. There's no way that you can recover files,but you can remove infection by asking for help in Virus Spyware and Malware Logs forum. I'd like to help you but FRST,Hijack This and DDS logs aren't allowed to be posted here,only in mentioned forum.

Hi yellownerd :)

You have been infected with the CTB-Locker/Critroni Ransomware (or one of their variants). In order to keep this section organized and not see hundreds of threads created for the same issue, you should seek assistance in the CTB-Locker Support Thread linked below.

CTB Locker or DecryptAllFiles.txt Encrypting Ransomware sets extension to .CTBL

If you want to know more about this particuliar infection and see what you can do to prevent it and/or attempt to recover your files, consult its FAQ below.

CTB Locker and Critroni Ransomware Information Guide and FAQ

This being said, I contacted a Moderator and requested this thread to be closed to avoid confusion.

Good luck!
