Windows Defender Security Warning: What Is an “Unknown Publisher” Warning? The Windows Defender Security Warning presents itself as an important warning from Microsoft that your computer might be at risk due to security issues.

Here’s what this warning is, why you should ignore it, and how to remove it from your computer.

Why you’re Seeing this Warning

You may be getting the Microsoft Defender security warning for several reasons.

Here are a few Potential Reasons:

You went to a hacked website that led you to the hoax page.

You have a device with harmful adware loaded.

The pop-up notice can appear after it displays and persists every time you enter your browser, so trying to close the session might not be the solution.
