-- Added filtering to improve scan stability and prevent engine crashes
-- Additional performance improvements to prevent concurrent scans. This change ensures that if a quick or full scan is already running, no additional quick or full scan scans are initiated from `MpCmdRun` or Powershell (`Start-Scan`).
-- Resolved the issue where subfolder exclusions were not being honored in Microsoft Defender Antivirus scans related to non-Microsoft SIEM solutions. This fix ensures that specified subfolders are now correctly excluded from scans, preventing unnecessary detections and improving overall system performance.
