    Hi guys,

    It appears as though this has been on my computer for quite some time, but I've just realised exactly what it is, and now I understand why my system has been under performing lately. The virus is stopping Windows Update from working, slowing my browsing, causing pop ups, and being generally annoying.

    I've read a lot about it, and still no luck with the removal. I'm in the same situation as most. I can detect it, and delete it with SpyBot Search and Destroy and Malwarebytes Anti Malware, but it just comes back straight away.

    I would love some professional step by step help from you guys, so I can finally get rid of it. I have read the 'READ & RUN ME FIRST' post, and completed all the steps involved.

    Please tell me which log files (if any) you would like me to post. So we can begin this removal.

    I look forward to your help,

    Thanks a lot!

    Xhai.

    Welcome to Major Geeks!

    The infection you have is known to infect router hardware. If you have a router hooked up then you need to follow the instructions for your hardware and reset it to factory default settings. Normally there is a recessed push button type switch that needs to be held down for some number of seconds to do this. After resetting to factory defaults on your router, you will need to reconfigure the router for your network if you have made any changes to the default network setup.

    Uninstall the below software:
    Viewpoint Media Player <-- should have been uninstalled in step 1 of the READ ME

    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:
    O2 - BHO: (no name) - {02478D38-C3F9-4efb-9B51-7695ECA05670} - (no file)
    O2 - BHO: NCO 2.0 IE BHO - {602ADB0E-4AFF-4217-8AA1-95DAC4DFA408} - (no file)
    O2 - BHO: (no name) - {7E853D72-626A-48EC-A868-BA8D5E23E045} - (no file)
    O3 - Toolbar: (no name) - {7FEBEFE3-6B19-4349-98D2-FFB09D4B49CA} - (no file)
    O4 - HKLM\..\Run: [QuickTime Task] "C:\Program Files\QuickTime\QTTask.exe" -atboottime

    After clicking Fix, exit HJT.

    Now delete all files in the below folder except ones from the current date (Windows will not let you delete the files from the current day).
    C:\Users\Valued Customer\AppData\Local\Temp

    Now run Ccleaner!

    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 log:
    • C:\MGlogs.zip
    Make sure you tell me how things are working now!

    Hi Chaslang, thanks very much for your help.

    I've completed the tasks you said. Here is the requested log file.

    It looks as though the pop ups have stopped. But i'll wait to get the 'all clear' from you before i get too excited.

    Thanks again,

    Xhai

    Your MGlogs.zip file was not updated properly and show some of the same logs as last time. Run the C:\MGtools\GetLogs.bat program again and make sure that you let the program finish running before closing the command prompt window.

    Then attach the new C:\MGlogs.zip file so we can properly verify the previous fix.

    Here's the log again. Hopefully it's updated this time.

    No it is not. Delete the current C:\MGlogs.zip file. Then shut down any protection software. Then run the C:\MGtools\GetLogs.bat program again and make sure you allow it to finish running. Do not close the command prompt window until you see it tell you that it is finished. See the snapshot here: Using MGtools

    Here it is again. I deleted the .zip file and made sure that all protection software was shutdown, then ran the GetLogs program again. I made sure the program had finished running before I did anything else. The 2 times prior to this, I definitely let the program finish as well.

    Hopefully this one is better.

    Thanks for your help.

    Okay this log is incomplete and shows that several scans are not even running which is why things are not getting updated. You must be getting errors like those mentioned in the Using MGtools procedure. Perhaps you are not even noticing them.

    I see the below logs in your C:\MGtools folder. Please attach them here:
    • hijackthis.log
    • newfiles.txt
    • runkeys.txt

    Okay your logs are clean.

    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 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" /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:

    All done!

    Thanks so much for all your help, I really appreciate it. My computer is running a lot better now.

    Just while I have you, in the 'How to Protect yourself from malware!' thread, which of the free Anti Virus software would you say is the best one to get? Also, is there any pay anti virus software that you would recommend? Something a bit less memory hungry than Norton antivirus?

    Thanks again!

    AVG used to be at the top of the heap but AVG8 has become a big and has too many problems and false positives. You can eliminate some of the issues with AVG8 by not installing some of their included software (like LinkScanner). Stick with Avira or Avast for now. See how you like whichever you try. If you like it, buy it and get more features and support. Whatever you do, stay away from security suite packages.
