Overview​

This category contains scripts to disable various notifications from Defender Antivirus.

Defender Antivirus, built into Windows, protects your device from malware and other threats 1. It analyzes your data using machine learning and cloud-based protection technologies 1. This data analysis raises privacy concerns.

Key features of Defender Antivirus include:

  • Real-time protection against known and new threats 1
  • Behavior-based detection to identify suspicious activities 1

Defender Antivirus typically sends notifications when:

  • Scans are completed (both scheduled and manual) 2
  • Threats are detected 2
  • System status changes occur 2

These notifications appear on your device and in the Notification Center 2 (previously known as the Action Center 3).

Disabling these notifications may:

  • Enhance privacy by reducing visible information about your system's security status
  • Improve system performance by reducing background processes

However, disabling notifications may:

  • Lower your awareness of security threats
  • Increase the risk of unnoticed malware or system issues

The scripts in this category apply to both the standard Defender Antivirus and the Defender for Endpoint suite 1 2.

Caution

Disabling security notifications may prevent you from noticing critical system threats. This may reduce your security if you do not have alternative measures in place.
