Privacy and Security Open Windows Security in Windows 11

  • Staff

Windows Security is built-in to Windows 11 and includes an antirvirus program called Microsoft Defender Antivirus. Your device will be actively protected from the moment you start Windows 11. Windows Security continually scans for malware (malicious software), viruses, and security threats. In addition to this real-time protection, updates are downloaded automatically to help keep your device safe and protect it from threats.

Windows Security is your home to view and manage the security and health of your device.
  • Virus & threat protection - Monitor threats to your device, run scans, and get updates to help detect the latest threats. (Some of these options are unavailable if you're running Windows 10 in S mode.)
  • Account protection - Access sign-in options and account settings, including Windows Hello and dynamic lock.
  • Firewall & network protection - Manage firewall settings and monitor what’s happening with your networks and internet connections.
  • App & browser control - Update settings for Microsoft Defender SmartScreen to help protect your device against potentially dangerous apps, files, sites, and downloads. You'll have exploit protection and you can customize protection settings for your devices.
  • Device security - Review built-in security options to help protect your device from attacks by malicious software.
  • Device performance & health - View status info about your device’s performance health, and keep your device clean and up to date with the latest version of Windows 10.
  • Family options - Keep track of your kids’ online activity and the devices in your household.
  • Protection history - Where you can go to view actions that Microsoft Defender Antivirus has taken on your behalf, Potentially Unwanted Apps that have been removed, or key services that are turned off.
This tutorial will show you different ways to open the Windows Security app in Windows 11.

If you have another antivirus app installed and turned on, Microsoft Defender Antivirus will turn off automatically. If you uninstall the other app, Microsoft Defender Antivirus will turn back on automatically.
