    How To Find The Virus Who Used rundll32.exe To Make Pop-ups?


    So, I used a pop-up detect tool, and I found some process executed this command:"C:\WINDOWS\SYSTEM32\RUNDLL32.EXE" C:\Users\91345\AppData\Local\sord\begonia.jpg,main 5.As you might know, I deleted begonia.jpg. Pop-up solved! However, it still pop up that notification sometimes: I tried asking ChatGPT, but it did not help much in this case. Do you have a way to find which virus a .exe file or something else used rundll32.exe?

    :)

    rundll32.exe error in windows 10

    Hi Aaron,

    Rundll32.exe is an application that is used to launch functionality stored in shared .dll files, because
    DLL (Dynamic Link Library) files can't be launched directly.

    Here are methods that we can do to resolve Rundll32.exe errors in Windows 10:

    Method 1 – Replace the corrupted file using Startup Repair:

    • In the search box, type Recovery options. Double-click Recovery options.
    • Go to Advanced startup, click Restart now.
    • A blue window will pop-up, select Troubleshooting.
    • Select Advanced options > Startup Settings >
      Restart.
    • On the new list with settings that will appear, select Enable debugging.

    Method 2 – Use the scannow command:

    • In the search menu, type cmd.
    • Right-click Command Prompt >Run as administrator.
    • Type the command sfc/scannow and press Enter.
    The sfc/scannow command will scan all protected system files, and replace corrupted files.

    Method 3 – Replace the corrupted Rundll file:

    • Download a copy of the Rundll32.exe file from the Internet.
    • Replace the missing or corrupted Rundll file with the new one.
      • Go to windows\system32\rundll32.exe.
      • Paste the new rundll32.exe file.

    NOTE: Downloading a copy of the Rundll32.exe
    file from the Internet may cause system issues, virus and malware infection.


    The entire risk arising out of the use of the downloaded file remains with you.

    Update us with the outcome so we can provide further assistance.
     
  3. remove Rundll32.exe. virus

    Hi Conrad,

    Rundll32.exe is a program used to run program code in DLL files which is part of Windows components. There are viruses that uses this name also that's why it's commonly mistaken as a real virus. There are also times that the file gets replaced
    with a malware infected one. I suggest that you use the System File Checker tool to scan your system files and to repair missing or corrupted system
    files. The sfc/scannow command (System File Check) scans the integrity of all protected operating system files and replaces incorrect,
    corrupted, changed or damaged versions with the correct versions possible. You may refer to this link for
    more information.

    I will wait for your response.

    Regards.

    if for some reason you can't see the image, then the problem is Rundll32, which is a windows host process. It run's it self multiple times at the same time consuming all of my resources. This is a fresh copy of Windows 10, MalwareBytes show no signs of virus or malware on the file or the PC it self.

    I've tried what was suggested in this thread: Solved CEIP - rundll32.exe high CPU use in Win 10? - Windows 10 Forums

    But it didn't help, I would appreciate a little more help, please.

    Process Explorer, doesn't show anything useful, just say's n/a or simply blank fields.
