More Info:
Easy to get, easy to use—Because Microsoft Security Essentials is available at no cost, there's no registration process that requires billing or personal information collection. It installs after a quick download and Genuine Windows validation and then stays automatically up-to-date with the latest protection technology and signature updates.
Quiet Protection—Microsoft Security Essentials doesn't get in your way. It runs quietly in the background and schedules a scan when your computer is most likely idle. You only see alerts when you need to take action
