MS Security Essentials


MS Security Essentials is a program developed by Microsoft. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). When installed, it will add a context menu handler to the Windows shell in order to provide quick access to the program. The software installer includes 28 files and is usually about 26.17 MB (27,437,730 bytes). A majority of the PCs this is running on, most OS versions are Windows 7 (SP1). The distribution of this has mostly been seen in the United States.
