About Microsoft Security Essentials

Review
Editors Review
This is the rare bright spot in Microsoft’s security record. Even hardcore users swear by Microsoft Security Essentials’ ability to catch threats that have made it through the third-party protection software. A key reason behind this program’s effectiveness of the fact that its made by the same people behind the Windows OS, who naturally would be more familiar with the vulnerabilities facing it.
Microsoft Security Essentials is a free security software for Windows-based PC that caters high-quality protection against viruses and spywares including worms, Trojans, malware, and other malicious softwares.

Microsoft Security Essentials automatically updates and can be upgraded if necessary. It also has a status indicator that allows users to identify whether the computer is protected or not.

Finally, Microsoft Security Essentials operates quietly and alerts users when there is computer security urgency.
