question "rundll32.exe".

From a week ago, I noticed that the circle next to my mouse pointer came back few seconds on all like something was running or trying to open. I went to Task Manager & under 'Process' saw the rundll32.exe appearing in the list whenever it was running. How can I keep this from happening, or at least keep me to know is running? Thank you.

    My office was attacked by malware. I have run virus scan and all updates that were available. When the operating system starts, a window opens asking me to "choose the program you want to open this file: file: rundll32.exe.". There are recommended programs and other programs, but I'm fairly certain that none of them are correct. Can anyone help direct me in the right direction to solving this problem?

    Hello

    Just in case there are persistent pieces of malware here is the method of complete elimination.

    Try Mode safe mode with networking - repeatedly, press F8 that you start.

    The best two methods allow scanners to run and/or AV.exe out of the way or removing.

    1.
    CTRL SHIFT ESC - task manager OR right click on the taskbar - task manager

    Process tab - complete the process on AV. EXE and continue with the uninstall Guide.

    If necessary use start - computer or Windows Explorer to navigate to

    C:\Program Malwarebytes Anti - Malware\mbam.exe or where it is installed - if
    necessary right click on the shortcut of Malwarebytes - Properties - tab - target line to see where it
    is installed.

    Right-click on it and rename it to ZZMbam.COM (or something different than now) and
    Double-click it, and then run it like this. You can rename it back later. Do the same with
    other programs according to the needs. Use this method to others as needed - NOT assume all
    a program deletes all or that it is no other malicious software.

    2.
    Another method is to use them:

    Use Process Explorer to "Suspend" the process will not stop

    Hello

    Rundll32 errors can be caused by malware.

    If you need search malware here's my recommendations - they will allow you to
    scrutiny and the withdrawal without ending up with a load of spyware programs running
    resident who can cause as many questions as the malware and may be more difficult to detect as the
    cause.

    No one program cannot be used to detect and remove any malware. Added that often easy
    to detect malicious software often comes with a much harder to detect and remove the payload. Then
    its best to be thorough than paying the high price later now too. Check with them to one
    extreme overkill point and then run the cleaning only when you are sure that the system is clean.

    It can be made repeatedly in Mode safe - F8 tap that you start, however, you must also run
    the regular windows when you can.

  • Games of not launching, rundll32.exe keeps CPU usage

    Hello, I have encountered this problem several times and I am completely irritated by it.

    By chance, it happens with any game installed on my PC, in which the game after the launch through the Games Explorer or the shortcut for the program will fail to run and when I see the the Task Manager or process explore, a process called rundll32.exe uses the processor, which is launched after the charge of the exe of the game.

  • Windows cannot find C:\WINDOWS\system32\rundll32.exe

    Hello

    Can someone help me, I am trying to open files and folders, and all I get is Windows can't find C;\WINDOWS\system32\rundll32.exe and stop me so gains access. I was told that I could find the file on another computer stick in my memory stick and reapply, only problem I have is I don't know where its located. I'm on windows XP.

    Thank you very much

    Thanks for the suggestion, Lisa!  I tried the link but it says page is more noticed.

    You happen to know any other solution for that darn missing file?  I can't open all the apps in my control panel! ACK!

    Someone found a solution to this problem yet?  Thanks a lot for any attempt to answer!

    :)

    EDIT: I GOT IT!  Browsing the internet, I came across this answer:

    Find a copy of rundll32.exe in the folder c:\windows\system32\dllcache or c:\windows\servicepackfiles\i386.
    If you find it, go ahead and copy rundll32.exe in the c\windows\system32 of the system folder.

    Otherwise you need a windows disk to extend this fichier.* *.

    I have dd a search on my computer for the file "rundll32.exe" and he came in two different folders on my hard drive.  But it MUST be in c:\windows\system32 (file there lack of).  I found the file in the folder dllcache as shown above, then simply copied and pasted in the system32 folder.  And WALLAH!  Problem solved and control panel and all the rest works just fine now!  So simple!  I hope it works for you, the people who are still struggling with this problem!
