In Windows 7, Windows Defender primarily focused on spyware protection and did not provide comprehensive real-time virus protection.

The Malicious Software Removal Tool (MSRT) is a utility designed to remove specific, prevalent malware from already infected systems, not to provide continuous, active real-time protection or scanning.

Microsoft Security Essentials (MSE) was a free antivirus software package provided by Microsoft for Windows 7 (and Vista/XP) that offered real-time protection and active scanning for viruses, spyware, and other malware. Action Center, in contrast, is a centralized location for system alerts and notifications, not a security scanning engine itself.
