Rootkit Problem

    I've been having BSOD & Lockup problems. I'd assumed a hardware issue and have pursued a few things along that line (I assume you don't want this history here), but noticed some ugly redirect from Google searches in Firefox, which led me to the README & RUN THIS thread. While I've found malware problems, I'm not sure if it's related to my BSOD/lockup problem or not. At this point in time the redirects are still there and the machine locked up while trying to start a thread here.

    I've attached the four logs I could save. I couldn't get RootRepeal to finish and save a log, even after 18 hours. The window on that program did report:
    mbr rootkit detected
    hiberfil.sys locked to Windows API​
    but nothing else.

    Let me know if you need any other info, HJT logs, minidump info from my BSOD's, etc.

    thanks in advance for your help

    Welcome to Major Geeks!

    Please run the below procedure and attach the GMER log:

    GMER - running with a random name


    If you run into any problems trying to run it then shutdown all protection software and any disk emulation software (see step 6 of the READ & RUN ME) and then try running it.

    Here's the gmer log.

    As a side note, I seem to have lost internet connectivity on that machine as of yesterday afternoon. Got a BSOD while trying to mess with the network adapter, and one this morning trying to launch Chrome. Any insight appreciated.

    Thanks

    Please download HelpAsst_mebroot_fix.exe by noahdfear and save it to your Desktop
    • Double click HelpAsst_mebroot_fix.exe to run it and follow any prompts.
      • If the tool detects an mbr infection
        • please allow it to run mbr -f and shutdown your computer.
        • Upon restarting, please wait about 5 minutes after bootup, and then click Start>Run and type the following bolded command, then hit Enter.
          • helpasst -mbrt
        • Make sure you leave a space between helpasst and -mbrt

      • If the tool DOES NOT detect an mbr infection and completes running:
        • Click Start>Run and type the following bolded command, then hit Enter.
          • mbr -f
        • Make sure you leave a space between mbr and the -f
        • Now, please do the Start>Run>mbr -f command a second time.
        • Now shut down the computer (do not restart, you must shut it down), wait a few minutes then start it back up.
        • Give it about 5 minutes after the bootup and then click Start>Run and type the following bolded command, then hit Enter.
          • helpasst -mbrt
        • Make sure you leave a space between helpasst and -mbrt

    No matter what happens with the above, attach the above logs and then immediately continue with the below in normal boot mode!

    Now download The Avenger by Swandog46, and save it to your Desktop.

    • Your PC should reboot, if not, reboot it yourself.
    • A log file from Avenger will be produced at C:\avenger.txt and it will popup for you to view when you login after reboot.
    Now run Ccleaner. Only use the Run Cleaner button. Do not run anything else on any other forms.

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator).


    Then attach the below logs:
    • C:\avenger.txt
    • C:\MGlogs.zip
    Make sure you tell me how things are working now!

    I ran your prescribed procedure, here are the logs.

    I'm posting from the (formerly?) infected machine, and it's successfully connected to the net again and things seem to be working much faster than they have been.

    I'm posting using Chrome, but a brief test of Google using Firefox doesn't have the redirects happening like they used to. My test is a google search on "malware removal" and I had a lot of redirects to dodgy sites like stopzilla. Google still offers up these WOT red circled sites, but I'm not getting redirected to them.

    I'll have to see if this solves the BSOD issue, that'll take a little time.

    Thanks for your help, let me know if I'm done after you review my logs. Splendid help here, I assume there's a donation procedure?

    You're welcome. Your logs are clean.


    If you are not having any other malware problems, it is time to do our final steps:
    1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
    2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
      • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
      • "%userprofile%\Desktop\combofix" /uninstall
        • Notes: The space between the combofix" and the /uninstall, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
    3. Go back to step 6 oof the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
    4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    6. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    7. Go to add/remove programs and uninstall HijackThis.
    8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
      related to MGtools and some other items from our cleaning procedures.
    9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures pointed to by step 7 of the READ ME
        for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.
    10. After doing the above, you should work thru the below link:

    Thanks again, I'll run the clean up procedure.

    I have one remaining question: this machine was on a LAN with two other computers running XP, is there a chance this thing would have spread? Should I follow the README & RUN THIS procedure on those computers to see if something turns up? They don't exhibit any of the behavioral problems that the now repaired machine had.

    If you had file/drive sharing in effect, there is a possibility that the infection could have been spread to the other drives.

    I suggest that you start by looking for the files and folder I had you delete with Avenger
    If these exist, the PC is definitely infected.
