    I originally deleted portions of the malware with Avast. After the computer rebooted, it seemed the virus was gone, however, the internet would not come on. After a few hours of experimentation, I discovered that remnants of the rootkit remained, which I removed with Combofix. The computer, however, is still unable to connect to the internet. Here are some of the logs I have compiled from the various programs I have used:

    I have gone through the entire process. The computer still cannot access the internet. There is no detected malware on the computer remaining, from what I can tell. The browsers are not able to access the internet, even though the internet says it is connected.

    This is all of the logs requested. The combofix log is uploaded in the previous post entitled "1.2.12.txt"

    It is in the order of
    SuperAntiSpyware.
    Malwarebytes Anti-Malware log
    RootRepeal
    MGlogs

    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!
    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 needs to update to a new version, make sure you allow it to update.
    * 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:
    ClearJavaCache::
    KILLALL::
    
    File::
    C:\Documents and Settings\User\Local Settings\Application Data\ph08tqhh1ic1766ud2565uk5ls1wr7e4
    C:\Documents and Settings\All Users\Application Data\ph08tqhh1ic1766ud2565uk5ls1wr7e4
    C:\Documents and Settings\User\Templates\ph08tqhh1ic1766ud2565uk5ls1wr7e4
    C:\WINDOWS\system32\drivers\60965959.sys
    C:\Documents and Settings\User\Local Settings\temp\16488296.cvr
    C:\Documents and Settings\User\Local Settings\temp\16488359.od
    C:\Documents and Settings\User\Local Settings\temp\neng0.ico
    C:\Documents and Settings\User\Local Settings\temp\neng1.ico
    C:\Documents and Settings\User\Local Settings\temp\neng2.ico
    
    
    * 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 previous file with the same name, click YES.
    * Now use your mouse to drag CFscript.txt on top of ComboFix.exe
    [​IMG]
    * 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.

    Note: If after running Combofix you discover none of your programs will open up, and you recieve the following error: "Illegal operation attempted on a registry key that has been marked for deletion". Then the answer is to REBOOT the machine, and all will be corrected.

    Please download MiniToolBox and save it to your desktop and run it by right clicking and selecting Run As Administrator.


    Checkmark following checkboxes:

    • Flush DNS
    • Report IE Proxy Settings
    • Reset IE Proxy Settings
    • Report FF Proxy Settings
    • Reset FF Proxy Settings
    • List IP configuration
    • List Winsock Entries
    • List Devices -> All
    • List last 10 Event Viewer log

    Press Go and attach the result (Result.txt) that pops up. A copy of Result.txt will be saved in the same directory the tool is run from.




    Now download Windows Repair by Tweaking.com and unzip the contents into a newly created folder on your desktop.

    • Now open Repair_Windows.exe
    • Go to Start Repairs tab.
    • Choose "Custom Mode" and press "Start".
    • Create a System Restore point if prompted.
    • In the Custom Mode window, select the following repair options:
      • Repair Windows Firewall
      • Repair Internet Explorer
      • Repair Hosts File
      • Remove Policies Set By Infections
      • Repair Winsock & DNS Cache
      • Repair Windows Updates

    • Now click the Start button.
    • Be patient while the tool repairs the selected items.
    • If asked to reboot the computer for the changes to take affect, make sure other tasks in the program are not still running before accepting to restart.

    Reboot after running Windows Repair.

    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!

    I ran combofix, however, I was able to restore the network by using this thread:
    http://forums.majorgeeks.com/showpost.php?p=1696640&postcount=19

    I had already done the other portions of your recommendation previously, and I believe those logs are in my first post. But since my internet is now working, I figured I just needed to ensure that all of the malware was removed and I didn't need to do those repair portions again. My combofix log is attached.

    Once again, my internet is now working and the computer seems to be working flawlessly. Is there anything else I need to do?

    Good to know.

    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 real time protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.We recommend them for doing backup scans when you suspect a malware infection.
    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. Go back to step 6 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
    4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    6. 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.
    7. Go to add/remove programs and uninstall HijackThis.
    8. 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.
    9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures pointed to by step 7 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.

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