    Hey guys, I've recently got infected by a bunch of malware/spyware and got rid of most of them by following the vista cleaning procedure. However I wasn't able to run ComboFix since I'm on vista.

    None of the solutions were able to remove lsass.exe and snfq.exe located in C:\

    So here are my logs, any help would be greatly appreciated!!

    I don't believe Combo willl run on your system. So let's do this:

    Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

    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.

    Now 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.


    Continue by downloading a tool we will need - Pocket KillBox

    Now run Pocket Killbox by doubleclicking on killbox.exe
    Choose Tools > Delete Temp Files and click Delete Selected Temp Files.
    Then after it deletes the files click the Exit (Save Settings) button.
    NOTE: Pocket Killbox will only list the added files it is able to find on the system. So when you do the below, if some files do not show in the list after pasting them in, just continue.

    Select:

    * Delete on Reboot
    * then Click on the All Files button.*(or on the folders option)*
    * Please copy the file paths below to the clipboard by highlighting ALL of them and pressing CTRL + C (or, after highlighting, right-click and choose copy):
    * Return to Killbox, go to the File menu, and choose Paste from Clipboard.
    * Click the red-and-white Delete File button. Click Yes at the Delete on Reboot prompt.

    If you receive a PendingFileRenameOperations prompt, just click OK to continue (But please let me know if you receive this message!).

    If Killbox does not reboot just reboot your PC yourself.

    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 logs:

    * C:\MGlogs.zip

    Hi Tim,

    before you replied I was able to delete those files, by disconnecting the internet it let me delete them and I was able to clean the registry as well as the lines in HJT. Malwarebytes and SAS both returned nothing after running them but I'd like to be 100% sure that my system is completely clean! There are a few lines in HJT that I wasn't able to remove, it says (file missing) next to them but when I click fix they still come back...

    I still followed your advice and ran the fixME.reg file, it was successful. Here are the logs asked for.

    your help is really appreciated, thanks!

    I only asked you to remove on line in HJT...nothing else.

    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:
