Question

How do I remove the win32/cryptor virus?

Asked by: BriPC

I have a pc that I am working on that has the win32/cryptor virus on it found using AVG 8.5 free edition. The scans will pull it up, but freeze after about 30 mins and I have to hard boot the computer to get it to shut down. I downloaded Malwarebytes and spybot, and am unable to run the programs.   They come up in the task manager, but never open. I can run other applications like word, internet, win media player... just not any type of spyware removal programs it seems like.  I've run Hijackthis, but it doesn't pull up anything.

Here is a solution I found. Interesting read. (http://www.geekpolice.net/virus-spyware-malware-removal-f11/win32-cryptortough-to-kill-t13058.htm) Requires the Combofix.exe. The procedure is written up by Belahzur (second entry). It requires a renaming of the .exe for the download (links provided). I am putting this one in my toolbox.

You have to make this at boot-up. Try a boot cd like UBCD http://www.ubcd4win.com and run the tools from there

Do what Wolfhere says, rename the exe files to be able to launch them.

Reboot your PC in safe mode and run a full scan with AVG 8.5. Let us know, if you still have the problem.

 

by: rpggamergirlPosted on 2009-08-29 at 04:10:49ID: 25213704

Try renaming MalwareBytes or Combofix or any security tools before saving the file to your desktop.
Renaming it after it has been downloaded is not the same as renaming it before in contact with the infected pc.

Let us know if it still won't run.

Renaming and running the combofix tool worked perfectly and was way easy too! There is good info on the link provided, thank you very much!

HI: I just finished with this little "critter". I think it has evolved a bit over time. The advice to rename MBAM.exe and the install for Malwarebytes does work. My issue was that the virus kept coming back after every reboot. Malwarebytes would find it, remove it and ask for a reboot. I slowly caught on and put the drive in another machine. (Everyone should have a spare machine sitting around to clean things up with, right?) I went to the Windows\system32 directory of the infected drive and deleted the file (UACinit.dll) that was always coming back. There were also some more files that started with UAC, which were dll files too. I deleted tham as well(Be careful, desperation is a dangerous thing). I then cleaned out all temp directories and put the drive back in the system. After 3 more scans and finding some minor registry entries and stuff, the system comes up clean. This "Critter" is a real fiesty thing. Oh, I also turned off system restore during all this process too. Hope some of this helps someone else.
