    I've followed all the instructions and run all the scans in the read me thread. I couldn't successfully run the combofix scan. It just sat at the "preparing to run" screen. I've attached the logs. Please help. I've had this trojan for a while but its now slowed my internet connection to a crawl where its taken me almost a whole day to get these scans done. I appreciate any help!

    Welcome to Major Geeks!


    One of the first things mentioned in the READ & RUN ME and one of the most important which is why it is mentioned first is the below:
    You seem to have ignored this and it may also be the reason you could not get ComboFix to run. You have AVG7 Free and Avast installed. You need to uninstall one of these immediately and then reboot your PC.

    After reboot, try running ComboFix one more time after shutting down whichever antivirus you still have installed. If it runs, attach the log.

    Then Run this Disable/Remove Windows Messenger to remove Windows Messenger. Do not confuse Windows Messenger with MSN Messenger because they are not the same. Windows Messenger is a frequent cause of popups.

    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:

    R1 - HKCU\Software\Microsoft\Internet Explorer,Search = about:blank
    R1 - HKCU\Software\Microsoft\Internet Explorer,SearchURL = about:blank
    R1 - HKLM\Software\Microsoft\Internet Explorer,Search = about:blank
    R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Default_Search_URL = about:blank
    R1 - HKCU\Software\Microsoft\Internet Explorer\Search,CustomizeSearch = about:blank

    After clicking Fix, exit HJT.

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it.

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

    I can't uninstall AVG. I keep getting error and failed messages when I try to uninstall from both the uninstall icon or add/remove. Regardless, I was able to run combofix this time for some reason. I've attached the logs you requested. My connection already seems noticeably faster. Can you tell if I'm still infected? THANKS for the help!!

    None of the items in my previous fix were fixed. Did you run the Windows Messenger Removal tool to remove Messenger? Did you do the HijackThis fix? Did you select the items and then remember to click Fix checked after shutting down ALL browser windows. Run those to parts of the previous fix again and then continue with the below.

    Try using the below to uninstall both AVG7 and Avast:

    Your Uninstaller! 2008



    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.
    • 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.

    Copy the bold text below to notepad. Save it as fixme.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.
    Make sure that you tell me if you receive a success message about adding the above
    to the registry. If you do not get a success message, it definitely did not work.

    Now run Ccleaner!

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it.


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

    Your logs are free of malware but we have a little more to do to finish cleaning up from having multiple antivirus applications installed. We have a little more of AVG to remove.

    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:

    O4 - HKLM\..\Run: [AVG7_CC] C:\PROGRA~1\Grisoft\AVGFRE~1\avgcc.exe /STARTUP
    O4 - HKCU\..\Run: [AVG7_Run] C:\PROGRA~1\Grisoft\AVGFRE~1\avgw.exe /RUNONCE
    O4 - HKUS\S-1-5-19\..\Run: [AVG7_Run] C:\PROGRA~1\Grisoft\AVGFRE~1\avgw.exe /RUNONCE (User 'LOCAL SERVICE')
    O4 - HKUS\S-1-5-20\..\Run: [AVG7_Run] C:\PROGRA~1\Grisoft\AVGFRE~1\avgw.exe /RUNONCE (User 'NETWORK SERVICE')
    O4 - HKUS\S-1-5-18\..\Run: [AVG7_Run] C:\PROGRA~1\Grisoft\AVGFRE~1\avgw.exe /RUNONCE (User 'SYSTEM')
    O4 - HKUS\.DEFAULT\..\Run: [AVG7_Run] C:\PROGRA~1\Grisoft\AVGFRE~1\avgw.exe /RUNONCE (User 'Default user')
    O23 - Service: AVG7 Alert Manager Server (Avg7Alrt) - GRISOFT, s.r.o. - C:\PROGRA~1\Grisoft\AVGFRE~1\avgamsvr.exe
    O23 - Service: AVG7 Update Service (Avg7UpdSvc) - GRISOFT, s.r.o. - C:\PROGRA~1\Grisoft\AVGFRE~1\avgupsvc.exe

    After clicking Fix, exit HJT.


    Now we need to 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!
      • If it is not on your Desktop, the below will not work.
    • 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.


    Copy the bold text below to notepad. Save it as fixme.reg to your desktop (yes owverwrite the previous file). Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.
    Make sure that you tell me if you receive a success message about adding the above
    to the registry. If you do not get a success message, it definitely did not work.

    Now run Ccleaner!

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it.


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

    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. You can uninstall SUPERAntiSpyware now.
    2. We recommed you keep Malwarebytes Anti-Malware as a scanner. It uses no resources except a little disk space until you run a scan.
    3. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop & renamed it 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\cf" /u
        • Notes: The space between the cf" 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:\cf folder from combofix.
    4. If we used SmitFraudFix, you can delete all files and folders related to it now including the c:\rapport.txt log.
    5. If we used VundoFix, you can delete the VundoFix.exe file and the C:\VundoFix Backups folder and C:\vundofix.txt log that was created.
    6. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    7. 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.
    8. Go to add/remove programs and uninstall HijackThis.
    9. You can delete the C:\MGtools folder and the C:\MGtools.exe file. You can also delete the C:\MGlogs.zip
    10. 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.
    11. After doing the above, you should work thru the below link:
