Microsoft Security Essentials provides real-time protection for your home PC that guards against viruses, spyware, and other malicious software for Windows 64-bit OS.

Microsoft Security Essentials works with Windows Security Center in Windows Vista and Windows 7 Action Center to provide users with up-to-date information about their current level of protection, and alerts users when real-time protection is off or the signature status is out of date.

Microsoft Security Essentials is a free download from Microsoft 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.

Windows Security Center and Windows 7 Action Center also notify the user of important Microsoft Security Essentials events via standard notifications.

Real-time protection such as that found in Microsoft Security Essentials is a great tool in the fight against known malicious software; however, improving the overall health of the ecosystem also requires addressing malware at the distribution source. Studies have found that a substantial number of sites offering counterfeit product keys, pirated software, key generators or crack tools attempted to install malicious or unwanted software. Multiple examples also exist of malware embedded within counterfeit products. Once infected, these PCs are more likely to become malware hosts spreading malicious software to other machines in the ecosystem.
