Overview​

This category contains scripts that disable various file activity monitoring features of Defender Antivirus.

These features are designed to protect your system by monitoring file activities, but they may also compromise your privacy and affect system performance.

Disabling these components enhances privacy by limiting the collection of data about your system, usage, and files.

These scripts may also improve system performance during file operations.

However, disabling these features may reduce your system's security. Without these monitoring features, Defender Antivirus may be less effective at detecting and blocking certain types of malware or unauthorized file activities.

Caution

Disabling these features can make your system more vulnerable to malware, ransomware, and unauthorized file access.
