This program is important for the stable and secure running of your computer and should not be terminated or deleted. If you delete it, you will encounter issues while running some applications on your system. Check and ensure that the particular rundll.exe is situated in the WinSxS, System32 or SysWOW64 folders. If so, it is the legitimate Microsoft process; else it could be a virus.

The following is, primarily, based on the fruitful discussion at TechNet, and the important points have been culled out from there and presented here.

If you get this error message frequently, here are a few troubleshooting steps you may try:

Fix Rundll32.exe error

1] Update Windows

First and foremost, ensure that your Windows is fully updated.

2] Turn off Thumbnails view

If you get the error when opening folders that contain video files, turn off the thumbnails view and see if it helps:

Open Control Panel > Folder Options > Always show Icons, Never Thumbnails

3] Check program installations

Try to remember, when did this error start popping up.

Was it after installing a particular program? Was it after installing, say, Nero ? if yes try this:

Open Computer > System Drive > Program files > Common Files > Ahead > DSfilter. Rename “NeroVideoProc.ax” to say “1NeroVideoProc.ax”. Also rename “NeVideo.ax” to say “1NeVideo.ax”

Reboot.

Maybe you could update or uninstall Nero software and see if it helps.

4] Update Codec Pack

The Intel ViiV software and the K-Lite Codec Pack too are known to cause this problem. If you have installed any of them, update them or uninstall them and see if it helps.

5] Troubleshoot in Clean Boot State

Follow these steps to try and find out, which software is causing this issue.

Run msconfig to open up the System Configuration Utility window. Click on Services, and check the “Hide all Microsoft services” checkbox. Click on “Disable All” button.

Now click on the “Startup” tab, and then click on “Disable All” button again. Press the OK button and then “Restart” button on the following window.

Effectively, you have turned off all non-Microsoft services and startups.

If the issue is resolved, open System Configuration Windows again and then enable all the services from Services tab and then check the issue after restarting the computer in the same way as mentioned above disabling one service at a time.

6] Disable DEP

Turn off Data Execution Prevention and see if it helps. But remember that this is a security feature that is there to help protect your computer.

7] Run Troubleshooter

Run the Microsoft Windows File and Folder Troubleshooter and see if it helps.

This way, you will have to enable/disable services and start-ups to narrow down on the culprit. Agreed, this is a lengthy and painfully boring process, but it will help you identify the culprit.

How do I know if rundll32 is a virus?

Every application running on a Windows computer is digitally signed by the developer. By viewing the digital signature, you can easily identify whether or not a particular program or file is a virus. To do so, open the Properties of a file and select the Digital Signatures tab. You will see the digital signatures there. If the Digital Signatures tab is not available in rundll32 properties, you can view its copyright under the Details tab. You can also scan the rundll32 file with your antivirus or Windows Defender.

Rundll32 is a Windows utility responsible for loading and running 32-bit Dynamic Link Library (DLL) files. These files contain data and program code, and they're often used by more than one Windows program at the same time. If a message displays on one of your office computers warning that Rundll32 has stopped working, it can be difficult to pinpoint the exact cause. The problem could be with the Rundll32 utility, a corrupt DLL or one of the programs calling the DLL. In other cases, the culprit could be a piece of malware using the same file name as the Rundll32 utility to disguise itself as a valid Windows process.

• Log in to Windows using an administrator account.
• Uninstall or roll back any driver (especially if it’s a video driver) or software you may have installed just before the problem started. Reboot your system and see if the Rundll32 error message persists. If it doesn't, the problem has been resolved and you can skip the remaining steps.
• Launch your anti-virus software and run a full system scan. Clean or quarantine any infected items found and then reboot your system. Run follow-up scans until the system comes up clean.
• Log back in to your system (if necessary) with an administrator account.
• Click Start, type “cmd” (without quotes) in the Search box and press “Enter.”

Type “sfc /scannow” and press “Enter.” Windows will scan all your system files (including Rundll32) and repair any damaged files. Reboot your computer when the scan is complete.
