2. Use a dedicated DLL repair tool

For a lot of us going through recovery and digging into advanced settings can be quite challenging.

We recommend a more effective and versatile way of dealing with this issue: to let dedicated software do the work for you.

Keep in mind that manually replacing DLL is risky and should not be done unless you manage to back up your registry appropriately before doing so.

3. Use a PowerShell command

1. Press Windows Key + X to open Win + X menu. Now choose Command Prompt (Admin) or PowerShell (Admin) from the list.
   
2. Now enter sfc/scannow and press Enter to start the SFC scan.
   
3. Remember that this scan can take about 15 minutes or more, so don’t interfere with it.

Sometimes this problem can occur due to file corruption. File corruption can appear for various reasons, and if you have problems with the Rundll32.exe error, you might be able to fix the issue by running the SFC scan.

Once the scan is finished, check if the problem persists. If you can’t run an SFC scan or if the issue is still present, you might be able to fix the problem by running the DISM scan instead.

To do that, follow these steps:

1. Start Command Prompt as administrator.
2. Enter and run this command: DISM /Online /Cleanup-Image /RestoreHealth
   
3. DISM scan will now start. It’s worth mentioning that this scan can take more than 20 minutes, so don’t interrupt it.

Once the DISM scan is finished, check if the problem is resolved. If you could not run an SFC scan before, be sure to run it after the DISM scan is finished and check if that solves your issue.

4. Clear your browser’s cache and close all tabs

Several users reported a Rundll32.exe error in their browsers. If you’re having this problem, you will most likely have a scamming website in one of your tabs.

If this problem occurs in your browser, try to clear your browsing history and cache. If that doesn’t work, close the tab that is giving you this message; everything should go back to normal.

You can also open a different browser and check if the issue reappears. If not, it means you have a scamming website on the other browser.

Regardless of the message in the browser, your PC isn’t infected, and your files aren’t corrupted, so there’s no need to worry. Close that tab, and the issue won’t appear anymore.

5. Check your antivirus

If you’re getting a Rundll32.exe error on your PC, your antivirus is the most likely cause. However, several users reported that the leading cause was the sandbox feature of their antivirus.

According to users, Rundll32.exe was added to the sandbox on their antivirus, and that caused the issue to appear. So, to solve the problem, you need to remove Rundll32 from the sandbox and check if that solves the problem.

Users reported that some antivirus software might block non-malicious apps or processes. Therefore, we recommend you change your antivirus settings.

If changing the antivirus settings doesn’t solve the issue, you might have to remove your antivirus. There are several ways to do that, but the best is using a dedicated removal tool.

You can download the antivirus removal tool from your antivirus developer for free. Once you remove the antivirus, check if the issue persists. If not, it means that your antivirus was causing the problem.

To ensure the problem doesn’t reappear in the future, it’s advised to switch to a different antivirus solution. In addition, you can find alternative security software that doesn’t interfere with other apps or processes on your system.

For a seamless experience, we recommend you try an antivirus with low CPU usage, as it can keep your PC fully protected without negatively impacting its performance.
