Microsoft Security Essentials is a free antivirus program for Windows 7 by Microsoft Defender, formerly known as Windows Defender, which is a component of Windows 10. This guarantees that every Windows 10 user, including those who opt not to install an antivirus program, always has one set up and operating. Windows 10 will turn off any outdated antivirus software you may have installed and turn on Microsoft Defender. The same Microsoft Defender antivirus program is also included in Windows 11.

The background service that runs continuously in the background of Microsoft Defender is the Antimalware Service Executable process.
