Scroll down to the bottom of the right-hand panel and click Settings.Open Edge and click the triple-dot button in in the upper-right.
Here's how to toggle SmartScreen off and on in Edge: You can disable SmartScreen in the Windows Defender Security Center app in total or just for Edge, but for the latter it's faster to do so right within Edge itself, particularly if you are already using Edge. I don't recommend turning SmartScreen off completely because it is helpful in preventing you from downloading a malicious file or app, but you can disable it in Microsoft's Edge browser if you want to override its protection and go ahead and download a file it doesn't recognize.
On some occasions, however, you may find SmartScreen overstepping its bounds and blocking you from downloading a file you know to be safe. One of the ways Windows Defender keeps your computer safe from internet evils is by employing its SmartScreen tool to keep you from downloading potentially harmful files or visiting malicious sites.
