Microsoft Defender SmartScreen protects against phishing or malware websites and applications, and the downloading of potentially malicious files.

Microsoft Defender SmartScreen helps protect your device from malicious sites and downloads while you browse the web in Microsoft Edge.

You can turn on or off Microsoft Defender SmartScreen for Microsoft Edge if wanted in Windows 11.

On = Warns users that sites and downloads are potentially dangerous but allows the action to continue while running in Microsoft Edge.

Off = Turns off Microsoft Defender SmartScreen, so a user isn't alerted or stopped from downloading potentially malicious apps and files.

Microsoft Defender SmartScreen determines whether a site is potentially malicious by:
  • Analyzing visited webpages for indications of suspicious behavior.
  • Checking the visited sites against a dynamic record of reported phishing sites.
If Microsoft Defender SmartScreen determines that a page is malicious, it will show a warning page to notify the user that that site is reported as unsafe. The next screenshot shows an example of a Microsoft Defender SmartScreen warning page when a user tries to open a malicious website.
