Issue: How to Fix Error code: rundll32.exe?

Hi. Why am I seeing an Error code: rundll32.exe on Chrome? My PC runs Windows 10 if that makes a difference.

Solved Answer


Error code: rundll32.exe is a very misleading pop-up message, which should not be trusted. Technically speaking, rundll32.exe is a system file responsible for calling Windows DLL files and loading them into PC‘s memory, which is why the error related to it should be regarded as a serious one. However, this case is a little bit different. In contrast to system errors, Error code: rundll32.exe is run while using web browsers (Google Chrome, Mozilla Firefox, IE, Safari, etc.) only, what means that it’s browser specific. The message says:

Confirm Navigation
The problem is caused by an unusual activity performed on this machine. Error code: rundll32.exe. Call Microsoft Support Number Now – +1-844-988-6363 and share this code with the agent.

In reality, Error code: rundll32.exe is related neither to .dll file nor to a PC virus. It‘s a rogue technical support scam, which is triggered by an adware program. In other words, this message is a sign that you have recently installed a bundled freeware and agreed upon the installation of it‘s attachments (plug-ins, add-ons, etc.). Therefore, DO NOT fall for believing that your PC ran to a serious issue and DO NOT try to call the number provided because it’s just an attempt to trick you and swindle your money.

Although rundll32.exe error pop-up is not malicious on its own, it may become a very irritating experience because as long as you keep a related adware, the message will pop up from time to time. On top of that, it can‘t be closed easily, which is why you may need to close web browser by force quite frequently. Therefore, do not ignore the emergece of this error and fix Error code: rundll32.exe issue right now.
