It shows the detected items, quarantined items, and allowed items. In the history section, you can check what was found when your computer was analyzed. If you don't have much experience, you can focus on the first two.

The program is divided into several sections: analysis, upgrade, history, and configuration. This makes Microsoft Security Essentials an ideal solution since it won't affect the use of your computer while it works. It also consumes very little resources, unlike antivirus suites made by third parties. You can use it without an Internet connection, too, so it can analyze your computer even if it's not online. It detects malware by consulting its huge database which is constantly and automatically updated. Microsoft Security Essentials is a real-time protection system that will protect your computer from all kinds of malware - like viruses, rootkits, and spyware - by analyzing your computer and alerting you whenever it detects unfamiliar and potentially dangerous elements.

Microsoft Security Essentials is a pack of tools designed for Windows 7 and earlier that adds a number of non-standard features for protecting your computer, including a comprehensive antivirus software called Windows Defender. For some time now, Microsoft has been developing its own antivirus software.
