About Microsoft Security Essentials

Review
Editors Review
Despite the historical aversion to freeware antivirus software, even hardcore users swear by Microsoft Security Essentials’ ability to catch threats that have made it through third-party protection software. It's possible that MSE may be the only AV software you need on Windows 7, and you won't have to spend a dime.
Microsoft Security Essentials is a security software suite for Windows that provides high-quality protection against viruses and spywares including worms, Trojans, malware, and other malicious software, all for free.

Microsoft Security Essentials automatically updates security definitions, and can be upgraded if necessary. It also has a status indicator that allows users to identify whether the computer is protected or not, and also comes with real-time protection to remove malware as it is detected, or attempts to infect the system.

Microsoft Security Essentials operates quietly and alerts users when there is computer security urgency. It also automatically scans USB drives and CDs that are inserted into your PC, checking if there is any malware within and removing as needed.

Microsoft Security Essentials only works on Windows Vista and 7, as it has been superseded by Windows Defender in 8 and 10.
