Microsoft offered non-beta and free version of Security Essentials software. It's anti-virus, anti-spyware and anti-other malicious software, that should work easy and quietly somewhere on our Windows Genuine PC where we don't see it. Microsoft said that Security Essentials provides real-time protection for home PC.

Company also said it's 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”.
