Periodic Scanning in Windows Defender is a useful feature available in Windows 10. Windows 10 is the most secure operating system Microsoft has ever shipped and it continues to make it better and more secure.
Periodic Scanning feature in Windows Defender
This new feature, Periodic Scanning improves system security by using Windows 10 built-in Windows Defender as an additional scanner if you have installed any third-party antivirus. This feature is offered only when you have installed a 3rd-party antivirus software and Windows Defender is disabled.
These periodic scans will utilize Automatic Maintenance – to ensure the system chooses optimal times based on minimal impact to the user, PC performance, and energy efficiency – or customers can schedule these scans. Limited Periodic Scanning is intended to offer an additional line of defense to your existing antivirus program’s real-time protection, says Microsoft.
With this feature of Periodic Scanning, one can configure Windows Defender to scan the system periodically even when other third-party antivirus software is installed and will provide additional Malware protection. So Microsoft is making malware detection and protection seamless and easier, even if the customer chooses to use a third-party antivirus.
By default, Periodic Scanning is not enabled. When enabled, Windows 10 will use the built-in Windows Defender scanning engine to periodically scan the PC for threats and remediate them. These Periodic scans will make use of Automatic Maintenance thus ensuring the system chooses optimal times based on minimal impact on the user and PC performance. Customers can also schedule these scans. Periodic Scanning offers an additional line of defense to the existing antivirus program.

Periodic Scanning becomes available when you have installed and are running any third-party antivirus solution. It is not enabled by default. So if you are not using the built-in Windows Defender as your antivirus program on Windows 10, one can enable Periodic Scanning as follows:
