    system32\cmd.exe POP-UP’s


    by stetienne1 ·

    Hi this is my first post, I apologize for any protocol errors. I’m trying to fix a friends computer but at startup I get 6 blank popup windows with “windows\system32\cmd.exe” headings. These then disappear one by one after about 10 seconds. Does anyone know what this is, if it is harmful, and how I can fix it? Many thanks, Nick.

      HiJack This V1.99.1 – double click the DL file and click UNZIP letting it extract to its default folder C:\Program FIles\HiJackThis, run it from there

      Fix these with HJT ? mark them, close IE, click fix checked

      O4 – HKLM\..\Run: [WINDOWS SYSTEM MANAGER] \spoolsvc.exe

      O4 – HKLM\..\RunServices: [WINDOWS SYSTEM MANAGER] \spoolsvc.exe

      O23 – Service: Local Security Authority Subsystem Service (lsass) – Unknown owner – C:\WINDOWS\lsass.exe

      Click Start > Run > and type in:


      Click OK.

      In the services window find this EXACT name

      Local Security Authority Subsystem Service

      Rightclick and choose “Properties”. On the “General” tab under “Service Status” click the “Stop” button to stop the service. Beside “Startup Type” in the dropdown menu select “Disabled”. Click Apply then OK. File-Exit the Services utility.


      Restart your computer into safe mode now. (Tapping F8 at the first black screen) Perform the following steps in safe mode:

      Double-click on Killbox.exe to run it. Now put a tick by Standard File Kill. In the “Full Path of File to Delete” box, copy and paste each of the following lines one at a time then click on the button that has the red circle with the X in the middle after you enter each file. It will ask for confimation to delete the file. Click Yes. Continue with that same procedure until you have copied and pasted all of these in the “Paste Full Path of File to Delete” box.


      Note: It is possible that Killbox will tell you that one or more files do not exist. If that happens, just continue on with all the files. Be sure you don’t miss any.

      Exit the Killbox.

      START ? RUN ? type in %temp% OK – Edit ? Select all ? File ? Delete
      Delete everything in the C:\Windows\Temp folder or C:\WINNT\temp
      Empty the recycle bin

      go to the run box and type msconfig
      hit enter and uncheck any start up items or services that are unneeded and reboot and see if they go away

      A couple of [i]other[/i] things to try …

      by older mycroft ·

      First, what is appearing in your Event Viewer after Windows had finished loading? ‘System’ or ‘Application’ might have entries for the timeouts of the pop-ups.

      Also, try running ‘Autoruns’

      It may give a better view of the errant routines. If you find ’em, untick ’em. 🙂

      Couple of T’s & Q’s

      Check your Startup Folder to see if there is anything in there, you should be looking for .BAT .CMD or it could be a disguised .EXE.

      Check these settings in the Registry as well. A call like this from the Registry could invoke a CMD.exe The value parameter in a RunOnce entry is a quoted string that has the following form: “Rundll32[.exe] DllName,EntryPoint[Arguments]”




      Check what Processes are running. Quick check in Taskmanager for any instances of CMD.exe

      Do a search for .bat and .CMD files on the PC you can check them and you may be able to associate them with something.

      Add these lines to Boot.ini and check the Logs.

      multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=”Microsoft Windows XP Professional” /fastdetect /NoExecute=OptIn /SOS /bootlog

      This will create a file in c:\windows named Ntbtlog.txt

      Read the file and look at what has been loaded.

      Also download and install CCleaner to tidy up your Registry. Let it run through until there are no errors left.

      How long has this been happening. What have you installed recently. If it is only recent try a System Restore.

      “windows\system32\cmd.exe”.. A solution maybe..

      This usually opens when a batch file is created. have you created one recently, or have you downloaded something with it in it?
      What is a batch file exactly?
      It is a file containing a series of DOS commands i.e. a very basic scripting language.
      This might be a solution to your problem:

      Download & run the Fixswen.inf file. Save the fixswen.inf file to your local hard disk, right-click on the file and choose install.

      Please post back if you have any more problems or questions.
