How to enable or disable Windows Defender Antivirus Periodic Scanning on Windows via Windows Security

Windows Defender Periodic Scanning

Microsoft Defender Antivirus offers “Periodic Scanning,” which scans and removes threats that other antivirus software may have missed. Consider periodic scanning as an added layer of defense against cyber threats if you use an antivirus product other than Windows Defender (CrowdStrike Falcon, Bitdefender, McAfee, and so on). It’s a mechanism for identifying and preventing computer threats that works with both Microsoft’s antivirus software and third-party antivirus software on Windows 10 and 11. If you have Windows Defender real security turned on, Limited Periodic Scanning is enabled by default. When you turn on periodic scanning, Microsoft Defender remains inactive, but it will monitor for threats that your existing antivirus might miss. Individuals who use Microsoft Defender as their primary antivirus on their machine can enable Microsoft Defender to check for viruses on a regular basis by following this extensive guide: Periodic Scanning: How to schedule Windows Defender Antivirus to scan on Windows | Learn [Solve IT].

According to Microsoft, this feature is not recommended for use in enterprise environments. This is a feature aimed mostly at individual users. Periodic Scanning detects malware using a limited subset of Microsoft Defender Antivirus capabilities and will miss most malware and possibly harmful apps since they are managed by the primary antivirus. Management and reporting capabilities will be restricted as well.
