    My system seems to behave suspiciously since few days ago with excessive internet activities even when I'm not using the web browser. I run HJT and saw a BHO mpaxpdp.dll and try to delet the entry but unsuccessful. Manual deletion of the file and key in registry were unsuccessful as well. Tried using ComboFix, Avenger and HJT to delete the file upon reboot also fails. Looking at the file shows the original flename as smveri32.dll. Searching the web points me to this forum.

    I had followed the instructions READ & RUN ME FIRST. Malware Removal Guide for Win Xp. Attached are the log files. Appreciate your help.

    Let's start with this:

    Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

    Run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator). This is really HijackThis (select Do a system scan only) and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:
    After clicking Fix, exit HJT.

    Now let's use ComboFix to remove a bunch of malware files.

    * 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 ):
    Code:
    KILLALL::
    
    
    Drivers::
    ddcdf00c
    d7899bb5
    82727004
    fnq6123
    
    File::
    C:\yapf.exe
    C:\-1462033705
    c:\windows\lk00000000.tmp
    C:\Documents and Settings\Rick\Local Settings\Application Data\40FFABB5-81E8-45D2-A645-74940137EC3C.txt
    C:\Documents and Settings\Rick\Application Data\st00000000.tmp
    c:\windows\system32\mpaxpdp.dll
    c:\windows\system32\mpaxpdp.dll
    c:\windows\system32\riqynoy.dll
    c:\windows\system32\drivers\ddcdf00c.sys
    c:\windows\system32\drivers\82727004.sys
    
    
    Registry::
    [-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{40FFABB5-81E8-45D2-A645-74940137EC3C}]
    
    
    * 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 and also attach the log from Combo.

    Hi, Thank you for your response. Some information you may want to know. While waiting for the response, I'd removed NAV and installed Avast Antivirus and Comodo Firewall as recommended by this site. Avast perform a bootup scan and managed to detect and delete many virus file. At the same time, I was able to remove the BHO using HJT after the Avast scan which was not possible before.

    Please see attached logs after performing as your instructions.

    Your logs look good. Are you still having any problems>

    If you are not having any other malware problems, it is time to do our final steps:

    1. We recommed you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no real time protection. They are useful as backup scanners. 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" /u
        • Notes: The space between the combofix" and the /u, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.

      • Delete the C:\combofix folder from combofix (if it exists)

    3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    4. 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.
    5. Go to add/remove programs and uninstall HijackThis.
    6. You can delete the C:\MGtools folder and the C:\MGtools.exe file. You can also delete the C:\MGlogs.zip
    7. If you are running Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning steps in the READ ME for your Window version and see the steps to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.

    8. After doing the above, you should work thru the below link:
