    Noticed that the internet was slow and that I was getting a Google redirect in the last week or so.
    Tried the READ ME FIRST process, but I don't think it is completely gone.
    Your help is greatly appreciated.

    I want you to run TDSSKiller so refer to the below for how to do so.

    TDSSkiller - How to run


    Please also download MBRCheck to your desktop
    • Double click MBRCheck.exe to run (vista and Win 7 right click and select Run as Administrator)
    • It will show a Black screen with some information that will contain either the below line if no problem is found:
      • Done! Press ENTER to exit...
    • Or you will see more information like below if a problem is found:
      • Found non-standard or infected MBR.
      • Enter 'Y' and hit ENTER for more options, or 'N' to exit:
    • Either way, just choose to exit the program at this point since we want to see only the scan results to begin with.
    • MBRCheck will create a log named similar to MBRCheck_07.16.10_00.32.33.txt which is random based on date and time.

    We need to use ComboFix by sUBs

    • 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 quote box. Ensure you scroll down to select ALL the lines:
    Code:
    KILLALL::
    
    DirLook::
    c:\documents and settings\Desk\Local Settings\Application Data\{3E2ACFA1-7C48-11E1-826D-B8AC6F996F26}
    c:\documents and settings\All Users\Application Data\F4D55F170000706500037C80D151FC4E
    
    Registry::
    [HKEY_LOCAL_MACHINE\software\microsoft\windows nt\currentversion\winlogon]
    "Userinit"="c:\windows\system32\userinit.exe," 
    [HKEY_LOCAL_MACHINE\software\microsoft\windows nt\currentversion\svchost]
    "NecUsb3Sevic"=-
    
    File::
    C:\windows\system32\USB3Nw32.dll
    
    • 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

      [​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.

    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.


    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. (Right click and run as admin if using Vista or Windows7) Then attach the new C:\MGlogs.zip file that will be created by running this.

    Let me know of any problems you may have encountered with the above instructions and also let me know how things are running now!

    Ran Combofix with the additional script. Still detected Rootkit.ZeroAccess! inserted itself in tcp/ip stack.
    Combofix restarted the computer a couple of times then ran Getlogs.bat.

    Error occurred with Getlogs
    "Unexpected error has occurred at proceedure: Modregistry_IniGetstring(sFile=system.ini, sSection=boot, sValue=Shell)
    Error #5 invalid procedure call or argument"

    Your continued assistance is greatly appreciated.

    Combofix is still detecting Rootkit.ZeroAccess! inserting itself into tcp/ip stack.

    Also, when I use Google to search sometimes the search results appear flush left and sometimes they appear centered in a column on the left half of the page.

    Perhaps I need to run the Google redirect process? (but only if & when instructed).

    • Did Combofix now still report rootkit activity?
    • Run Combofix again now (right after running the above scrip) and let me know if it still complains about it.

  15. Kestrel13!

    Kestrel13! Super Malware Fighter - Major Dilemma Staff Member

    Thanks for your patience. Chaslang has advised me on how to proceed. :)

    Download OTL to your desktop.

    • Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
    • Vista and Windows 7 users Right-click OTL and choose Run as Administrator)
    • When the window appears, underneath Output at the top change it to Minimal Output.
    • Check the boxes beside LOP Check and Purity Check.
    • Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.

    When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.

    Attach both of these logs into your next reply.

    Ran OTR without issue and have logs. However, trying to start using F8 does not give me an option to "Repair Computer" (I'm using XP).
    When I start the Windows Recovery Console, I cannot enter the appropriate commands in the prompt (I only have "C:\Windows\_"

    Please advise about XP steps and I cannot locate my install disc.

    Sorry my bad. Please attach the OTL log.

    Please download this and transer it to your PC.

    Please download Farbar Service Scanner and run it on the computer with the issue.

    • Check all the boxes.
    • Press "Scan".
    • It will create a log (FSS.txt) in the same directory the tool is run.
    • Please copy and attach the log to your reply

    OTL logs attached and ran Farbar, but it gave a log names FRST.txt (not FSS.txt as noted in your previous post).

    Ran fix in OTL, got log.
    Ran Combofix, popup indicated that Combofix expired so it ran at "reduced functionality". That log is Combofix- R.txt. No rootkit indicated.
    Deleted and re-downloaded Combofix. That log id Combofix.txt. Again no rootkit indicated.

    Ready for final steps!
     
  24. Kestrel13!

    Kestrel13! Super Malware Fighter - Major Dilemma Staff Member

    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. 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:
