    Hello,

    A co-worker had some malware activity on his computer. I ran scans, and found a Java exploit using MS Security Essentials, and a TDSS rootkit was found in SUPERAntispyware. I removed those, and walked through the rest of the steps of the MajorGeeks Malware Removal Guide. When I ran ComboFix, though, I got a warning saying that McAfee Antivirus was running, and I needed to disable it before continuing. But McAfee is not installed on this computer. I checked the Add/Remove Software list, and it wasn't there, I checked the Remove Software list in CCleaner, and it wasn't there. I looked in the program files folder, and there was a McAfee folder, but it was empty. I looked at the running processes and the startup items, and it wasn't there.

    So I went ahead and ran ComboFix (it also wouldn't install the Windows Recovery Console), and continued with the Malware Removal guide steps. After completing, I went into Safe Mode and ran ComboFix there, and it again told me that McAfee Antivirus was running.

    Is this something I need to worry about? Is it possible that something is masquerading as McAfee? Or that it was uninstalled a while ago, but some vestiges are still running?

    Thanks for your help. I have included the log files from the scans that I ran.

    Here's the Root Repeal log. I had to run that again because I neglected to save the log before.

    Hello, dwhite10701

    I am reviewing your logs and will get back to you with instructions as needed. Please be patient!

    *Our queue is working the oldest threads first.

    *This is not the proper directory for MGTools.exe
    Quoting from Windows XP Malware Removal/Cleaning Procedure
    Move it now to either C:\ or to your Desktop.

    Step 1:
    Please download TDSSKiller.exe and save it to your Desktop. <-Important!!!
    • Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
      Vista/Windows 7 users right-click and select Run As Administrator.
    • If TDSSKiller does not run, try renaming it. To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123tdk.com).
    • Click the Start Scan button.
    • Allow the application to run if prompted by Windows or any security programs you have installed
    • Do not use the computer during the scan
    • It will start the scan and run rather quickly and will notify you of whether anything is found or not.
    • Follow the instructions to delete/quarantine if asks you what to do when if finds something.
    • Whether an infection is found or not, a log file should be created on your C: drive ( or whatever drive you boot from) in the root folder named something like TDSSKiller.2.1.1_27.12.2009_14.17.04_log.txt which is based on the program version # and date and time run.

    Step 2:
    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.
    Step 3:
    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 4:
    Now we need to use ComboFix.
    • 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
      [​IMG]
    • 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.


    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"... the answer is to REBOOT the machine, and all will be corrected.

    Step 5:
    Open CCleaner - select "Cleaner" > "Run Cleaner" <---use this function ONLY!

    Step 6:
    Please run this and attach the results.

    Using ESET's Online Scanner

    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 and the ESETscan.txtto your next reply.

    * Make sure you tell me if you had any problems running this procedure; and answer this - "What malware problems are you still experiencing?"

    Thank you for the help. I won't be back on the computer until Monday morning, but I will run these directions then and post the requested logs.

    You're welcome.

    We'll continue when you have the logs ready.

    Thank you, I went through the steps as instructed above. I've attached the MGLogs.zip file to this message. I ran the ESET online scanner, but when I finished, it said no threats were found, and just gave me the Finish button, without giving me an option to create a log file. I hope I didn't miss it, and I hope that this doesn't cause any problems for you.

    Thanks.

    You're welcome, dwhite10701

    Your logs look good! 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:
