App & browser control in Windows Defender Security Center provides the settings for Windows Defender SmartScreen, which 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.
Exploit Protection for your device
For your devices, Exploit Protection is already running and protecting your device. These protection settings will generally work for most people, however you can customize the settings for your device and the programs you run. If you manage devices and programs in an organization, you can use the export feature to share customized Exploit Protection settings across all devices in your organization.
