    Hello, guys I have been studying this forum for a day or two looking for answers. Sorry for the long message but I want to be informative as possible so I can get some help possibly. My p.c has recently become infected with some kind of virus or malware. After becoming infected I tried to start my computer and my explorer.exe wouldnt load. Only thing visible is my background and my mouse pointer.

    (2 Days Ago) I tried to load explorer.exe with task manager (new task run) but it gave the error "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." The explorer.exe file is in the right Windows folder though. So I updated MalawareBytes and tried to run it, but the program just disappeared. Same thing happened w/ Spybot. Ran in Safe Mode and installed both programs, ComboFix and SuperAnti Spyware. SuperAntiSpyware found some trojans/malware and got rid of them. Same thing with Malawarebtyes and Spybot. Forgot to mention that I couldnt connect to the internet for a while but the programs fixed that.

    (1 Day Ago) Tried to boot back up, explorer still didnt load, even in safe mode. Ran ccleaner it removed some things. Ran Bitdefender online scanner and it didnt find any trojans. Installed latest version of Java, but add/remove programs kept freezing when trying to delete old versions. Deleted the viewpoint programs as directed.

    (Today) I ran SAS again. It found a few things, dont know if they are major threats. I also ran MGTools. Now im stuck and I dont know what to do. BTW im using task manager to use the internet now. I tried to run Root Repeal, and when it got done it gave me an error. It didnt find anything suspect though while scanning. Any help would be appreciated.


    Windows XP Home Edition Version 2002 SP3, 64 bit version of Windows
    Intel CPU 2.7 GHz, 760 MB Ram
    Avast AntiVirus 4.8

    OK...now lets start with this:

    Please use add/remove programs to uninstall:
    J2SE Runtime Environment 5.0 Update 10"
    J2SE Runtime Environment 5.0 Update 6
    Java(TM) 6 Update 3"
    Java(TM) 6 Update 5"
    Java(TM) 6 Update 7

    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:
    NOTE: HJT may popup an error about the AppInit_DLLs line. Ignore it and click OK to continue.

    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.


    Now use windows explorer to find and delete:
    C:\WINDOWS\??curity\l?gonui.exe --> may be displayed as C:\Windows\Security\logonui.exe ( but make sure you check properties and that it is not an MS signed file)
    C:\Documents and Settings\All Users\Application Data\ycyzizeh.db
    C:\Documents and Settings\All Users\Application Data\yhorucoq.db
    C:\Program Files\Common Files\uxabisomuh.dat
    C:\scmhux.exe
    C:\WINDOWS\aqeb._sy
    C:\WINDOWS\fuli.com

    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

    Make sure you tell me how things are working now!

    Thank you for helping me. I did everything as you told me, and I still cant access windows explorer. It didnt open upon starting the pc and I still get the "access denied no permission" error when trying to load it through task manager. (both in normal and safe mode)

    Only 1 step I was confused about. When you said delete:

    C:\WINDOWS\??curity\l?gonui.exe --> may be displayed as C:\Windows\Security\logonui.exe ( but make sure you check properties and that it is not an MS signed file)

    I could not find the 1st you, gonui.exe. Also when I open logonui.exe through task manager, it took me to the screen where I log in my computers account. So I did not risk deleting this file.

    Also when I ran C:\MGtools\GetLogs.bat I didnt manually attach the C:\MGlogs.zip. (didnt see an option where I could attach it) When it finished scanning it said it added the C:\MGlogs.zip so I am assuming this ran as it was supposed to.

    • Please save Win32kDiag file to your desktop.
    • Click on Start->Run, and copy-paste the following command (the bolded text) into the "Open" box, and click OK. When it's finished,
      there will be a log called Win32kDiag.txt on your desktop. Please attach this log
    "%userprofile%\desktop\win32kdiag.exe" -f -r

    Thanks for all the help guys, everything seems to be working now. Its running a little slow, but working nonetheless.

    I ran the win32 program and attached the log below. When I restarted my pc combofix came up and started running. After it was done my Windows Explorer was back working..

    One again, you guys are the best.

    Your logs are clean. You may wish to post in the software forum regarding you issues with slowness.

    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 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.
    3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    4. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    5. 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.
    6. Go to add/remove programs and uninstall HijackThis.
    7. 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.
    8. If you are running Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures in step 3 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 ato create a new clean Restore Point.
    9. After doing the above, you should work thru the below link:
