    Hello,

    Scanning with Malwarebytes and subsequently MS Security Essentials I was alerted to the trojan Win:64/Sirefef.B on my laptop wich could not be removed. I now observe Win 7 shutdown in response to a warning message (in 1 min.) even in safe mode and I am pretty much unable to do anything further and pretty stuck at this point. Based on earlier threads I have obtained and run the Farbar Recovery Scan Tool form the command prompt and have attached the resulting FRST.txt and Search.txt files that were obtained from my system. Please help with a fixlist.txt. I understand that this needs to be created for each system individually which is why I posted this new thread.

    I was impressed with the farbar instructions and the smooth process and hope for help to get my system running again.

    Any help is highly appreciated.

    NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system

    Attached is fixlist.txt
    • Save fixlist.txt to your flash drive.
    • You should now have both fixlist.txt and FRST64.exe on your flash drive.

    Now re-enter System Recovery Options.
    Run FRST64 and press the Fix button just once and wait.
    The tool will make a log on the flashdrive (Fixlog.txt).
    Please attach this to your next message. (How to attach)

    Now attempt to boot normally.

    -------------------------------

    Re run FRST (no fix just a scan and attach log)



    I want you to run TDSSKiller so refer to the below for how to do so. (DO NOT just quit after running TDSSKiller and MBRCheck, there is MUCH more to do, scroll further down and follow the Read and Run Me First Malware removal procedures link.)

    TDSSkiller - How to run


    Please also download MBRCheck to your desktop
    • Double click MBRCheck.exe to run (vista and Win 7 right click and select Run as Administrator)
    • It will show a Black screen with some information that will contain either the below line if no problem is found:
      • Done! Press ENTER to exit...
    • Or you will see more information like below if a problem is found:
      • Found non-standard or infected MBR.
      • Enter 'Y' and hit ENTER for more options, or 'N' to exit:
    • Either way, just choose to exit the program at this point since we want to see only the scan results to begin with.
    • MBRCheck will create a log named similar to MBRCheck_07.16.10_00.32.33.txt which is random based on date and time.




    Now do not stop, please continue on with the below instructions too! :)

    Hello Kestrel13!

    I am truly impressed with your help! After I ran the fixlist that you provided I was able to reboot normally and I went through all the steps you listed including those in the malware removal guide and the Win7-specific steps. Everything worked as predicted. I followed instructions to clean what was found and attached all the logs. So far, for about one day the system seems to run normally. According to the instructions I did not remove anything found by the RogueKiller (just attached the log) and wonder whether I still have to follow up on this or take any other specific steps.

    This has been extremely helpful!

    I could only attach 5 files and will attach the remaining ones in a new reply.

    Sorry for a delay in a response. Been extremely busy.

    Please download these 4 files to your desktop.

    DHCP.reg
    BFE.reg
    BITS.reg
    MpsSvc.reg



    Boot into safe mode to do the below:

    • Now please click Start, and type regedit into the search box.
    • You should see a regedit.exe and icon appear in the Programs area of the Start Menu.
    • Right click on regedit.exe and select Run As Administrator
    • Then in the Registry Editor menu click File and select Import.
    • Navigate to the Dhcp.reg file saved to your Desktop and double click it. Allow it to be added to the registry. Repeat this for the three others.

    Now back into normal mode... and - Now run the C:\MGtools\GetLogs.bat file by double clicking on it. (Right click and run as admin if using Vista or Windows7) Then attach the new C:\MGlogs.zip file that will be created by running this.

    I added the four files to the registry in safe mode and attached the log subsequently created in normal mode. Everything worked smoothly!

    Many thanks again!

    Repeat the steps for BFE.reg please in any mode, and also go to start > and type in services.msc and click ENTER. Scroll down to the Background Intelligent Transfer Service if its listed and let me know it's status and start up type please.

    I added BFE.reg again to the registry in normal mode and found Background Intelligent Transfer Service listed with status blank (as opposed to other services sometimes listed as started) and start up type: Automatic (Delayed Start).

    Thanks again!

    Is Windows Update functioning?

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. (Right click and run as admin if using Vista or Windows7) Then attach the new C:\MGlogs.zip file that will be created by running this.
     
  10. pcuser

    pcuser Private E-2

    No, Windows Update gave a message that the service is not running (restarting did not change this). The new MGlog is attached. Many thanks again!

    Download Combofix to your desktop (DO NOT run it yet, and before we do following the below instructions, I would like for you to ENSURE your anti-virus/antispyware is all disabled!!)



    Now let's use ComboFix.

    * Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
    o If it is not on your Desktop, the below will not work.
    * Open Notepad and copy/paste the text in the below code box into it (make sure you scroll all the way down in the code box to get all lines selected ):

    * Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
    * At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
    * You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
    If it asks you to overide the prvevious file with the same name, click YES.
    * Now use your mouse to drag CFscript.txt on top of ComboFix.exe
    http://img.photobucket.com/albums/v666/sUBs/CFScriptB-4.gif
    * Follow the prompts.
    * When it finishes, a log will be produced named c:\combofix.txt
    * I will ask for this log below

    Note:

    Do not mouseclick combofix's window while it is running. That may cause it to stall.

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this

    Trying to get BITS back isn't going to be simple, let's keep trying.

    I want you to run TDSSKiller once more first, and attach the log.

    I ran TDSSKiller (after updating first) and it did not find any threats. Log is attached. Thanks again.

    I want you to run the Windows 7 - SFC /SCANNOW Command - System File Checker

    Once complete, let's move onto the below to have another pop at getting BITS back.

    Download the attached zip file which contains BITS.reg. Unzip BITS.reg to your desktop.


    • Now please click Start, and type regedit into the search box.
    • You should see a regedit.exe and icon appear in the Programs area of the Start Menu.
    • Right click on regedit.exe and select Run As Administrator
    • Then in the Registry Editor menu click File and select Import.
    • Navigate to the BITS.reg file saved to your Desktop and double click it. Allow it to be added to the registry. Let me know if you get a success message or not!

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. (Right click and run as admin if using Vista or Windows7) Then attach the new C:\MGlogs.zip file that will be created by running this.

    When I started the system I was surprised to see a message that it had (automatically) installed windows updates. As I reported earlier updates did NOT work when I tested it a few days ago. I hope this is good news.

    I ran SFC /SCANNOW and it did not find integrity violations. I added BITS.reg to the registry and received a success message! I ran MGtools and MGlogs.zip is attached.

    Many thanks again!

    Still not back in place as it should be. Hmm...

    • Open up Services again.
    • Right-click the Background Intelligent Transfer Service (BITS) service, and then click Properties.
    • On the General tab, next to Startup type, make sure that Automatic (Delayed Start) is selected.
    • Next to Service status, check to see if the service is started. If it's not, click Start.

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. (Right click and run as admin if using Vista or Windows7) Then attach the new C:\MGlogs.zip file that will be created by running this.

    The service was on automatic (delayed start) but gave an error message when
    I tried to start it: Error 1068 : The dependency service or group failed to start. MGlogs.zip is attached. Thanks again.

    Make sure these services are enabled, started, and set to automatic startup:

    • COM+ Event System
    • Remote Procedure Call (RPC)
    • DCOM Server Process Launcher

    Then try and start the BITS service again. Let me know what happens.
     
  20. pcuser

    pcuser Private E-2

    I found that RPC and DCOM Server Process Launcher had started and were set to automatic startup but COM+ Event System was not. I was able to start it and set it to automatic startup. After that I was NOW! able to start the BITS service set to automatic startup (delayed). Finally, I ran MGtools again and attached the log - just in case. Many thanks again and this looks like good news!

    Excellent! :) Everything is as it should be. Is everything acting as it should? No problems at all?
     
  22. pcuser

    pcuser Private E-2

    So far everything seems to work fine and I have now used a variety of programs without any problems. I assume then that I should re-enable user account control and toggle system restore and keep updating windows and keep MS security essentials active? Do you agree and do you recommend any other steps? This has been extremely helpful!
     
  23. Kestrel13!

    Kestrel13! Super Malware Fighter - Major Dilemma Staff Member

    Yes, I agree with you, I will provide the final steps below. :)

    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 of 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:
