    I am having a problem removing a browser redirect virus. I found numerous infections when running the scans but the problem persists. I have attached the log files as instructed. Additionally, I had been using KeePass to store passwords and URLs. KeePass will no longer run on this PC, no errors, just 99% processor activity with no application start. The history files showed inappropriate web activity that is likely the source of my problem. I appreciate any help you can provide.

    Welcome to Major Geeks!


    You need to download the current version of ComboFix.exe to your Desktop and delete the below which is not where we specified to save it.

    c:\tools\ComboFix\ComboFix.exe

    The same is true of the below which you need to delete:
    C:\Tools\MGtools\MGtools.exe

    You need to follow our instructions properly or things if you want them to work properly. Not following instructions can lead to a broken PC.

    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:

    R3 - URLSearchHook: Yahoo! Toolbar - {EF99BD32-C1FB-11D2-892F-0090271D4F88} - (no file)
    R3 - URLSearchHook: Zynga Toolbar - {7b13ec3e-999a-4b70-b9cb-2617b8323822} - C:\Program Files\Zynga\tbZyng.dll (file missing)
    O2 - BHO: Zynga Toolbar - {7b13ec3e-999a-4b70-b9cb-2617b8323822} - C:\Program Files\Zynga\tbZyng.dll (file missing)
    O3 - Toolbar: Zynga Toolbar - {7b13ec3e-999a-4b70-b9cb-2617b8323822} - C:\Program Files\Zynga\tbZyng.dll (file missing)
    O9 - Extra button: (no name) - {CD67F990-D8E9-11d2-98FE-00C0F0318AFE} - (no file)

    After clicking Fix, exit HJT.

    Now we need to 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!
      • If it is not on your Desktop, the below will not work.
    • Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
    • If ComboFix tells you it has expired or need to be updated to a new version, make sure you allow it to update.
    • Open Notepad and copy/paste the text in the below quote box into it:
    • 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.
    • Now use your mouse to drag CFscript.txt on top of ComboFix.exe
    • 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 Ccleaner. Only use the Run Cleaner button. Do not run anything else on any other forms.

    Now download the current version of MGtools and save it to your root folder. Overwrite your previous MGtools.exe file with this one.

    Run MGtools.exe ( Note: If using Vista make sure UAC is still disabled. Also don't double click on it, use right click and select Run As Administrator )

    Now attach the below log:
    • C:\ComboFix.txt
    • C:\MGlogs.zip
    Make sure you tell me how things are working now!

    OK, I did my best to follow your directions this time and so far my everything is working great. No more re-direct issues and KeePass will now run properly, can't thank you enough.

    Log Files attached as requested.

    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. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    4. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    5. 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.
    6. Go to add/remove programs and uninstall HijackThis.
    7. 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.
    8. If you are running Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures pointed to by step 6 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.
    9. After doing the above, you should work thru the below link:
