    Welcome to MajorGeeks!

    Please download SystemLook from one of the links below and save it to your Desktop.
    Download Mirror #1
    Download Mirror #2

    • Double-click SystemLook.exe to run it.
    • Copy the content of the following codebox into the main textfield:
      Code:
      [b]:filefind
      explorer.exe[/b]
      
    • Click the Look button to start the scan.
    • When finished, a notepad window will open with the results of the scan. Please attach this log in your next reply.
    Note: The log can also be found on your Desktop entitled SystemLook.txt

    *Then follow the below instructions:

    Please read ALL of this message including the notes before doing anything.

    Please follow the instructions in the below link:

    READ & RUN ME FIRST. Malware Removal Guide


    and then attach the requested logs to your next reply when you finish these instructions.
    • **** If something does not run, write down the info to explain to us later but keep on going. ****
    • Do not assume that because one step does not work that they all will not. MGtools will frequently run even when all other tools will not.
    • After completing the READ & RUN ME and attaching your logs, make sure that you tell us what problems still remain ( if any still do )!
    Helpful Notes:

    1. If you run into problems trying to run the READ & RUN ME or any of the scans in normal boot mode, you can run the steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:
    2. If you have problems downloading on the problem PC, download the tools and the manual updates for SUPERAntiSpyware and Malwarebytes ( links are given in the READ & RUN ME) onto another PC and then burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes, you could use a flash drive too, but flash drives are writeable and infections can spread to them.
    3. If you cannot seem to login to an infected user account, try using a different user account (if you have one) in either normal or safe boot mode and running only SUPERAntiSpyware and Malwarebytes while logged into this other user account. Then reboot and see if you can log into the problem user account. If you can then run SUPERAntiSpyware, Malwarebytes, ComboFix and MGtools on the infected account as requested in the instructions.
    4. To avoid additional delay in getting a response, it is strongly advised that after completing the READ & RUN ME you also read this sticky:
    * Any additional post is a bump which will add more delay. Once you attach the logs, your thread will be in the work queue and as stated - our system works the oldest threads FIRST.

    Sorry!

    I had a typo error in my "SystemLook" SL script - the punctuation mark should be a " . " <--- period not "comma"
    Code:
    [b]:filefind
    explorer.exe [/b]
    Please re-run ALL of my instructions in post #2.

    Logs to attach:
    • SASlog.txt log from SuperAntiSpyware.
    • Malwarebytes Anti-Malware log
    • RRlog.txt (from RootRepeal)
    • ComboFix.txt (normally C:\ComboFix.txt)

    Hello, INSANE111

    Combofix detected and replaced a couple of system files. We'll see what it detects in its next log.

    *Before we start, if you have not already please return your system to Normal Startup Mode as instructed in Step 4: of the R & R guide.

    *Other than the tools our guide instructed you to save there, I strongly recommend that you clean up this account's Desktop immediately leaving only shortcut links. [ C:\Users\Becky\desktop ] Do not store downloads, exe files, iso files....etc on your Desktop. First it is not a safe place to keep them (i.e., you may loose them due to malware, and a cluttered Desktop is an easy hiding place for malware), and last but not least - it can have an effect on your PCs performance.

    *Please rename C:\Users\Becky\Desktop\MGtools (1).exe to
    "C:\Users\Becky\Desktop\MGtools.exe

    Step 1:
    Please look in Add/Remove Programs (Programs and Features if using Vista or Windows 7) for the following and uninstall if found. If you get any errors just make a note and continue on.
    Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

    Step 2:
    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:
    After clicking Fix, exit HJT.

    Step 3:
    Now we need to use ComboFix to remove some malware and leftovers.
    • 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.
    • Make sure you have shut down all protection software (antivirus, antispyware, firewall...etc) programs so they do not interfere with the running of ComboFix. *Remember to re-start them before coming back online.
    • 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 inside of the below code box into it (make sure you scroll all the way down in the code box to get all lines selected ):
    • 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
      http://img.photobucket.com/albums/v666/sUBs/CFScriptB-4.gif
    • Follow the prompts.
    • When it finishes, a log will be produced named c:\combofix.txt
    Note:
    Do not mouseclick combofix's window while it is running. That may cause it to stall.


    Step 4:
    Delete all files and subfolders in the below folders except ones from the current date (Windows will not let you delete the files from the current day).
    Step 5:
    Open CCleaner - select "Cleaner" > "Run Cleaner" <---use this function ONLY!

    Step 6:
    Now install the latest Sun Java Runtime Environment

    Step 7:
    Then run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista or Windows 7, use right click and select Run As Administrator).

    Please attach the new C:\MGlogs.zip file to your next reply.

    * Make sure you tell me if you had any problems running this procedure. Is AVAST! detecting anything now? What malware problems are you still experiencing?

    *You must stop using MSconfig to control your startups; its function is for temporary troubleshooting only. Refer to the below link for properly dealing with them.
    Dealing with Startup Processes

    This does not belong on your desktop:
    C:\Users\Becky\Desktop\P._LimeWire_4.18.8_Pro.exe

    Step 1:
    Now download The Avenger by Swandog469, and save it to your Desktop.
    • Extract avenger.exe from the Zip file and save it to your desktop
    • Run avenger.exe by double-clicking on it.
    • Do not change any check box options!!
    • Copy everything in the Quote box below, and paste it into the "Input script here:" part of the window.
    • Now click the Execute button.
    • Click Yes to the prompt to confirm you want to execute.
    • Click Yes to the "Reboot now?" question that will appear when Avenger finishes running.
    • Your PC should reboot, if not, reboot it yourself.
    • A log file from Avenger will be produced at C:\avenger.txt and it will popup for you to view when you login after reboot.
    Step 2:
    Open CCleaner - select "Cleaner" > "Run Cleaner" <---use this function ONLY!

    Step 3:
    Then run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista or Windows 7, use right click and select Run As Administrator).

    Please attach the new C:\MGlogs.zip file to your next reply.

    * You also didn't answer these questions: "Is AVAST! detecting anything now? What malware problems are you still experiencing?"

    I would not know this unless informed, regardlessly - the questions that I ask need to be answered .
    *It should have been still disabled as instructed in the R & R ME FIRST guide.
    ...and against my advice, MSconfig is still being used to control Startups. :(

    Let's wrap this cleaning up:

    Delete all files and subfolders in the below folders except ones from the current date (Windows will not let you delete the files from the current day).

    Now open CCleaner - select "Cleaner" > "Run Cleaner" <---use this function ONLY!

    --------------------------------------------------------------------------

    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 re-enable 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 re-enabled 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 through the below link:
