With Windows 10 build 14352, Microsoft has introduced a new security feature which will be available in the final Anniversary Update. A new Periodic Scanning feature is an option of Windows Defender, which allows Defender to complement an alternative antivirus solution. So users who prefer to install some other antivirus software like Avast, Kaspersky, Symantec etc can get additional protection. Let's see how it works.
When you have just installed Windows 10, the operating system offers Windows Defender as the primary antivirus software out of the box. It is enabled by default and it is hard to disable even if you want to. In Settings -> Update & security ->> Windows Defender, it offers the following options to manage its security options:
Notice the option Real-time protection.
When the user installs an alternative antivirus software, the Windows Defender page changes its appearance and behavior in the Settings app. All settings become disabled, and the option "Real-time protection" changes its name to Periodic Scanning. See the following screenshot:
Note that this new option appears only if Windows 10 is able to detect the antivirus software you have installed, meaning that your antivirus should be compatible with Windows 10.
By default, Periodic Scanning is disabled. When enabled, Windows Defender acts like an additional antivirus scanner besides your primary antivirus. This should improve system security.
Once Windows Defender detects threats, the user will see a notification. While the application is mostly disabled in Periodic Scanning mode, its user interface still works and can be used to see update history, scan history and actions taken against previously detected threats.
If you are interested in testing Periodic Scanning in Windows 10, here is how you can try it.
How to turn on or off Periodic Scanning in Windows 10
This assumes that you have third party antivirus software installed. In my case, it is Avast! Free.

- Go to System - Update & security as shown below.

That's it. Periodic Scanning can be useful as a secondary security solution for users who run Windows 10 with another antivirus app and want to make sure that their PCs have the maximum level of protection. However, users who install a third party antivirus app usually do not trust Defender and are not happy with its protection level. For such users, this new feature is useless. What about you? Would you turn on this feature?
