Windows Defender Security Center provides the settings for Windows Defender SmartScreen. Windows Defender SmartScreen helps protect your device from potentially dangerous apps, files, websites, and downloads.
The settings on the App & browser control page let you:
- Block unrecognized apps, files, malicious sites, downloads, and web content.
- Set up warnings for unrecognized apps, files, malicious sites, downloads, and web content.
- Turn off blocking and warnings altogether.
Turning off the Block and Warn options may leave your device vulnerable to threats.
