Need help removing Smitfraud-C

    Tonight Spybot detected Smitfraud-C. I used Spybot to delete the problem, and right after doing so get a bunch of Spybot messages asking if I am allowing or denying a change in startup files. I get the same messages when I restart my computer. I have tried to accept and deny the changes, but it seems to make no difference. Everytime I re-run Spybot after a reboot, the trojan reappears. I have no idea what to do from here and was hoping someone could help me. A google search showed that Smitfraud-C is related to a file called windows/system32/drivers/core.cache.dsk, which I have detected on my system. I tried to remove this file but get a notice that access is denied. I'm not sure if this is related, but Microsoft Windows Security Center was disabled at the same time as Smitfraud showed up, and I can't figure out how to re-enable it. Thanks in advance!

    Saw that others asking for help have posted the results of Hijack This scan, so here it is:

    Welcome to Major Geeks!


    Please follow the instructions in the READ & RUN ME FIRST link given futher down and attach the requested logs when you finish these instructions.

    • If you have problems where no tools seem to run, please try following the steps given in the below and then continue on no matter what you find. You only need to try the TDSSserv steps if having problems getting scans in the Read & Run Me First.
    • 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.
    READ & RUN ME FIRST. Malware Removal Guide


    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 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, Malwarebytes and Spybot ( 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. To avoid addtional delay in getting a response, it is strongly advise that after completing the READ & RUN ME you also read this sticky Don't Bump! It Only Hurts You!!!. 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.

    You actually are fairly clean...lets do this:

    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.

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this and also attach the log from Avenger.

    You are quite welcome....your logs are clean. :)

    If you are not having any other malware problems, it is time to do our final steps:

    1. We recommed you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no real time protection. They are useful as backup scanners. 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" /u
        • Notes: The space between the combofix" 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:\combofix folder from combofix (if it exists)

    3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    4. 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.
    5. Go to add/remove programs and uninstall HijackThis.
    6. You can delete the C:\MGtools folder and the C:\MGtools.exe file. You can also delete the C:\MGlogs.zip
    7. 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.

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