Overview
This script disables notifications that can turn off security intelligence in Microsoft Defender.
This script prevents the antimalware service from receiving notifications to disable individual security intelligence 1 2 3. Security intelligence is updated information that helps antivirus software detect and protect against the latest threats, working with cloud-based protection 4. The antimalware service, also known as Microsoft Defender Antivirus, is essential to both Microsoft Defender and Microsoft Defender for Endpoint 5.
By default, Microsoft uses these notifications to disable security intelligence that may cause false positives 1 2 3. This functionality is provided by Microsoft MAPS (Microsoft Active Protection Service) 1 2 3. MAPS was previously known as Microsoft SpyNet 3 and is recently referred to as Cloud Protection 6. It operates by collecting potentially sensitive personal data 6.
Disabling these notifications limits Cloud Protection functionality, which inherently shares data with Microsoft 6. You also maintain more control over your system's security settings. However, this may reduce the accuracy of threat detection, possibly leading to more false positives.
This script primarily configures Defender Antivirus 1 4 5 6. It also applies to other Microsoft antimalware solutions such as: Microsoft Security Essentials 4, older Windows Defender 4, Microsoft Diagnostics and Recovery Toolset (DaRT) 4, System Center Configuration Manager 4, System Center Endpoint Protection 4 and Windows Intune 4.
This change enhances privacy but may reduce overall system security.
