What is Microsoft Security Essentials?
Microsoft Security Essentials is a free download from Microsoft (Space demand: only 17.63 MB.) that is simple to install, easy to use, and always kept up to date so you can be assured your PC is protected by the latest technology.
It’s easy to tell if your PC is secure — when you’re green, you’re good. It’s that simple.
Microsoft Security Essentials runs quietly and efficiently in the background so that you are free to use your Windows-based PC the way you want—without interruptions or long computer wait times.
MSE is available for Windows Vista and Windows 7 only and it's no longer actively supported and developed. Windows Security is for Windows 8, 8.1 and 10
