Microsoft Defender Advanced Protection Tips for Windows 11

Author: Dellenny

Windows 11 ships with Microsoft Defender Antivirus, providing comprehensive security without needing third-party software. While default settings offer decent protection, you can significantly improve security by enabling advanced features. Here’s how to get the most out of Defender:

1. Keep Microsoft Defender Updated

  • Defender regularly receives security intelligence updates from Microsoft.
  • Ensure Settings > Windows Update > Advanced options > Receive updates for other Microsoft products is enabled.
  • Run a Quick Scan after major updates for peace of mind.

2. Turn On Controlled Folder Access

  • Protect essential files from ransomware by enabling Controlled Folder Access:
    • Go to Windows Security > Virus & threat protection > Ransomware protection.
    • Enable Controlled folder access.
    • Add key folders (Documents, Pictures, OneDrive) to the protected list.

3. Use Tamper Protection

  • Prevent malware from disabling or changing security settings:
    • Navigate to Windows Security > Virus & threat protection settings.
    • Switch on Tamper Protection.

4. Enable Exploit Protection

  • Harden system defenses:
    • Go to Windows Security > App & browser control > Exploit protection settings.
    • Stick with default system-wide settings, and consider enabling ASLR and DEP for extra protection.

5. Use SmartScreen for Safer Browsing

  • Block phishing sites and unsafe downloads:
    • Go to Windows Security > App & browser control.
    • Enable Check apps and files and SmartScreen for Microsoft Edge.
    • Enable Potentially unwanted app blocking.

6. Enable Network Protection

  • Block connections to dangerous websites across all apps, not just your browser:
    • Open PowerShell (Administrator) and run: Set-MpPreference -EnableNetworkProtection Enabled

7. Run Microsoft Defender Offline Scan

  • Remove persistent malware:
    • Go to Windows Security > Virus & threat protection > Scan options.
    • Select Microsoft Defender Offline scan.
    • Your PC will reboot and run a deep scan before Windows starts.

8. Use Windows Security Notifications Wisely

  • Stay informed about threats:
    • Go to Windows Security > Manage notifications.
    • Keep essential notifications enabled; turn off nonessential ones if preferred.

9. Complement with BitLocker & Backup

  • Strengthen security further:
    • Use BitLocker drive encryption.
    • Maintain reliable backups (File History, OneDrive, or external drives).

10. Regularly Review Security Health

  • Monitor overall device health:
    • Open Windows Security > Device performance & health.
    • Check for issues and address recommendations promptly.

By enabling these advanced Microsoft Defender features, you can transform your Windows 11 system into a secure environment. Remember to keep your protection up-to-date and maintain safe online practices.
