Microsoft Security Essentials 4.10

Security system specifically designed to track down hidden services and software covertly operating on your system. Protects against various types of spyware, PUPs, and adware.

Microsoft Security Essentials is an anti-malware tool that can be installed for free on older versions of Windows, namely Windows Vista and Windows 7. The technical support for Windows XP is, unfortunately, no longer available. In newer versions, Windows Defender is used instead.

Security Essentials is easy to use. The user interface is fairly simple and offers most features right on the main window. Here you can scan your computer and choose among a quick, full or custom scan. Quick Scan checks specific parts of your computer, for example, OS drive, System Files, Registries. Full scan is a deep scan of your entire computer. The custom scan can be used to scan files or drives of your choice.

At the bottom of the main window, you can see the next scheduled scan and the last scan details. The window interface is color coded: green means everything is alright and you are well protected, yellow means there is some problem (either no scan performed or an update required) and red means virus or spyware are detected and you need to take some actions. Microsoft Security Essentials will alert you automatically in case of a yellow or red alert and recommend what to do. You can act directly from the notification area without having to enter the application. More
