    We don't use HJT around here anymore and you should NOT be running Combofix on your own.

    ========================================================================

    Please download SystemLook from one of the links below and save it to your Desktop.
    Download Mirror #1
    Download Mirror #2

    • Double-click SystemLook.exe to run it.
    • Vista users:: Right click on SystemLook.exe, click Run As Administrator
    • Copy the content of the following box into the main textfield:
      Code:
      :filefind
      wscntfy.exe
      tcpip.sys
      
    • Click the Look button to start the scan.
    • When finished, a notepad window will open with the results of the scan. Please post this log in your next reply.
    Note: The log can also be found on your Desktop entitled SystemLook.txt

    ========================================================================

    Combofix says:
    WARNING -THIS MACHINE DOES NOT HAVE THE RECOVERY CONSOLE INSTALLED !!
    Make sure to allow recovery console installation on next Combofix run.


    1. Please open Notepad
    • Click Start , then Run
    • Type notepad .exe in the Run Box.

    2. Now copy/paste the entire content of the codebox below into the Notepad window:

    Code:
    File::
    c:\windows\Vdevea.exe
    c:\windows\system32\bqmnt.exe
    c:\windows\system32\drivers\gbnt.sys
    
    
    DDS::
    uInternet Settings,ProxyOverride = <local>
    uInternet Settings,ProxyServer = http=127.0.0.1:6522
    
    Driver::
    trjmmbwl
    
    
    Registry::
    [HKEY_CURRENT_USER\software\microsoft\windows\currentversion\policies\explorer]
    "NoResolveTrack"=-
    [HKEY_USERS\.default\software\microsoft\windows\currentversion\policies\explorer]
    "NoResolveTrack"=-
    [HKLM\~\services\sharedaccess\parameters\firewallpolicy\standardprofile]
    "EnableFirewall"=dword:00000001
    
    
    

    3. Save the above as CFScript.txt

    4. Close/disable all anti virus and anti malware programs again, so they do not interfere with the running of ComboFix.

    5. Then drag the CFScript.txt into ComboFix.exe as depicted in the animation below. This will start ComboFix again.

    6. After reboot, (in case it asks to reboot), please post the following reports/logs into your next reply:
    • Combofix.txt

    logs

    ok...here are my two new logs

    ps i previously said it seemed to have worked - it deleted the one file (C:\WINDOWS\system32\drivers\mhgdwl.sys (Rootkit.Agent)) that i could not delete before that i thought was the source, but i am still getting pop ups....FWIW

    i didnt do anything other than running the scan in either program....no changing of anything.

    tjthomas TS Rookie Topic Starter Posts: 18

    also

    the text you had me copy and paste into a word file then drag into combo fix....is that unique to my problem/computer or is that a universal one..... i ask so that if anyone comes across this they know if they can use that......also, my wifes laptop is also infected with seemingly the same problem so i will have to do all this over for her computer and dont know if i can just use the same info.

    Thanks.

    All scripts are unique and shouldn't be used on any other computer under no circumstances.

    Please, delete your GMER file, download fresh one, run it and post new log.

    Freezing, while running GMER may happen. No worries.

    GMER log looks good :)

    Uninstall Combofix:
    Go Start > Run [Vista users, go Start>"Start search"]
    Type in:
    Combofix /Uninstall
    Note the space between the "Combofix" and the "/Uninstall"
    Click OK (Vista users - press Enter).
    Restart computer.

    ======================================================================

    Download OTL to your Desktop.

    * Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
    * Under the Custom Scan box paste this in:



    netsvcs
    drivers32 /all
    %SYSTEMDRIVE%\*.*
    %systemroot%\system32\Spool\prtprocs\w32x86\*.dll
    %systemroot%\system32\*.wt
    %systemroot%\system32\*.ruy
    %systemroot%\Fonts\*.com
    %systemroot%\Fonts\*.dll
    %systemroot%\system32\spool\prtprocs\w32x86\*.tmp
    %systemroot%\*. /mp /s
    /md5start
    /md5stop
    CREATERESTOREPOINT
    %systemroot%\system32\*.dll /lockedfiles
    %systemroot%\Tasks\*.job /lockedfiles
    %systemroot%\System32\config\*.sav
    %systemroot%\system32\user32.dll /md5

    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\Results\Install|LastSuccessTime /rs



    * Click the Quick Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
    • When the scan completes, it will open two notepad windows: OTL.txt and Extras.txt. These are saved in the same location as OTL.
    • Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post them back here.

    Update your Java version here: http://www.java.com/en/download/installed.jsp

    Note 1: UNCHECK any pre-checked toolbar and/or software offered with the Java update. The pre-checked toolbars/software are not part of the Java update.

    Note 2: The Java Quick Starter (JQS.exe) adds a service to improve the initial startup time of Java applets and applications. If you don't want to run another extra service, go to Start > Control Panel > Java > Advanced > Miscellaneous and uncheck the box for Java Quick Starter. Click OK and restart your computer.

    Now, we need to remove old Java version and its remnants...

    Download JavaRa to your desktop and unzip it to its own folder
    • Run JavaRa.exe (Vista users! Right click on JavaRa.exe, click Run As Administrator), pick the language of your choice and click Select. Then click Remove Older Versions.
    • Accept any prompts.

    It looks like your router is infected...

    Go Start>Run (Start search in Vista), type in:
    cmd
    Click OK (in Vista, while holding CTRL, and SHIFT, press Enter).

    In Command Prompt window, type in following commands, and hit Enter after each one:
    ipconfig /flushdns
    ipconfig /registerdns
    ipconfig /release
    ipconfig /renew
    net stop "dns client"
    net start "dns client"


    Turn the computer off.

    On your router, you'll find a pinhole marked "Reset".
    Keep pushing the hole, using a pencil, or a paperclip until all lights briefly come off and on.
    Restart computer and post fresh OTL "Quick scan".

    OTL log looks good now :)

    Doing so won't hurt, assuming your other computers are malware free.

    Last scans....

    1. Download Security Check from HERE, and save it to your Desktop.
    • Double-click SecurityCheck.exe
    • Follow the onscreen instructions inside of the black box.
    • A Notepad document should open automatically called checkup.txt; please post the contents of that document.


    2. Download Temp File Cleaner (TFC)
    • Double click on TFC.exe to run the program.
    • Click on Start button to begin cleaning process.
    • TFC will close all running programs, and it may ask you to restart computer.


    3. Go to Kaspersky website and perform an online antivirus scan.

    • Disable your active antivirus program.
    • Read through the requirements and privacy statement and click on Accept button.
    • It will start downloading and installing the scanner and virus definitions. You will be prompted to install an application from Kaspersky. Click Run.
    • When the downloads have finished, click on Settings.
    • Make sure these boxes are checked (ticked). If they are not, please tick them and click on the Save button:
      • Spyware, Adware, Dialers, and other potentially dangerous programs
      • Archives
      • Mail databases
    • Click on My Computer under Scan.
    • Once the scan is complete, it will display the results. Click on View Scan Report.
    • You will see a list of infected items there. Click on Save Report As....
    • Save this report to a convenient place. Change the Files of type to Text file (.txt) before clicking on the Save button. Then post it here.

    SecurityCheck reports:
    Make sure, you turn it ON!

    ====================================================================

    Update Firefox.

    ====================================================================

    Update Adobe Reader

    You can download it from http://www.adobe.com/products/acrobat/readstep2.html
    After installing the latest Adobe Reader, uninstall all previous versions.
    Note. If you already have Adobe Photoshop® Album Starter Edition installed or do not wish to have it installed UNcheck the box which says Also Download Adobe Photoshop® Album Starter Edition.

    Alternatively, you can uninstall Adobe Reader (33.5 MB), download and install Foxit PDF Reader(3.5MB) from HERE.
    It's a much smaller file to download and uses a lot less resources than Adobe Reader.
    Note: When installing FoxitReader, make sure to UN-check any pre-checked toolbar, or other garbage.

    =====================================================================

    Make sure to delete following file found by Kaspersky:
    - F:\Windows XP iso image file\GRTMPVOL_EN.iso
    Empty Recycle Bin afterward.

    =====================================================================

    OTL Clean-Up
    Clean up with OTL:

    * Double-click OTL.exe to start the program.
    * Close all other programs apart from OTL as this step will require a reboot
    * On the OTL main screen, press the CLEANUP button
    * Say Yes to the prompt and then allow the program to reboot your computer.

    If you still have any tools or logs leftover on your computer you can go ahead and delete those off of your computer now.

    Sometimes, running MBAM again will give you some new discoveries.
    Those were some registry entries. I don't see anything deadly.

    Are you done with all steps?
