defender periodic scanning

Defender periodic scanning is a Windows 10 and Windows 11 feature that allows Microsoft Defender Antivirus to perform occasional scans even when a third-party antivirus is installed. When a third-party security suite like Norton, Bitdefender, or Malwarebytes Premium is active, Defender normally disables its real-time protection to avoid conflicts. Periodic scanning provides an extra layer of security by running limited scans without interfering with the primary antivirus. This feature is useful for users who want occasional checks from Defender alongside their main antivirus. The tag covers how to enable and use limited periodic scanning, its benefits, and considerations for maintaining system security.
