Windows Security is built-in to Windows 10 and includes an antirvirus program called Microsoft Defender Antivirus. In previous versions of Windows 10, Windows Security is called Windows Defender Security Center.

The Windows Security app uses the Windows Security Service (SecurityHealthService or Windows Security Health Servce), which in turn utilizes the Security Center service to ensure the app provides the most up-to-date information about the protection status on the endpoint, including protection offered by third-party antivirus products, Windows.
