Microsoft Security Essentials is a built-in anti-malware component of Microsoft Windows that is delivered with Windows versions earlier than 8.
The Microsoft Security Essentials module allows you to configure Microsoft Security Essentials security policy and track its status via the Cyber Protection service console.
This module is applicable for the machines on which Microsoft Security Essentials is installed.
The Microsoft Security Essentials settings are almost the same as Microsoft Windows Defender Antivirus except the absence of the real-time protection settings and inability to define exclusions via the Cyber Protection service console.
