Protect Your PC: Microsoft Security Essentials

Microsoft Security Essentials guards against viruses, spyware, and other malicious software. It is a free download from Microsoft that is simple to install, easy to use, and always kept up to date. It’s easy to tell if your PC is secure — when you’re green, you’re good. It’s that simple. MSE also runs quietly and efficiently in the background so that you are free to use your computer without interruptions or long computer wait times.
