When MSE installs, the program configures itself based on your system. If you do not have one of those versions or opted not to install it, the download provided here lets you install it after the fact.

If you have a home edition of Windows XP, Vista or 7, you can install MSE alongside the OS. It may not be as sophisticated as the offerings from some of the bigger names in AV protection, but for the average home user, it is dependable and already installed in many cases. But MSE in practice proved to be quite effective. How good could it be was a common line of reasoning. This intent cause many to prematurely judge MSE. Prior to MSE, there were many systems running without any protection at all. The design goal of MSE was not necessarily to compete with Kaspersky Lab, McAfee, Symantec and so on but rather to ensure that the average user had some form of AV protection active. Microsoft developed and maintained MSE for Windows XP, Windows Vista and Windows 7. MSE is available free of charge to home users and small business that are using a supported Windows operating system. Microsoft Security Essentials-often abbreviated MSE-is an antivirus program that monitors for, detects, quarantines and eliminates viruses, spyware, trojan horses, rootkits and so forth. Microsoft Security Essentials is a freeware antivirus solution designed to protect Windows systems.
