Microsoft Security Essentials (MSE) is a free antivirus software product created by Microsoft that provides protection against different types of malware such as computer virus, spyware, rootkits and trojan horses for Windows. Microsoft Security Essentials replaces Windows Live OneCare, a commercial subscription-based antivirus service and the free Windows Defender, which only protected users from adware and spyware. Unlike Microsoft Forefront family of enterprise-oriented security products, Microsoft Security Essentials is geared for consumer use.
Microsoft Security Essentials provides real-time protection for your home PC that guards against viruses, spyware, and other malicious software.
Microsoft Security Essentials is a free download from Microsoft that is simple to install, easy to use, and always kept up to date so you can be assured your PC is protected by the latest technology. It’s easy to tell if your PC is secure — when you’re green, you’re good. It’s that simple.
Microsoft Security Essentials runs quietly and efficiently in the background so that you are free to use your Windows-based PC the way you want—without interruptions or long computer wait times.

MSE is a security suite designed for consumers and lacks centralised management features which are found in Microsoft Forefront Client Security. It includes the same anti-malware engine (dubbed “Microsoft Malware Protection Engine”, or MSMPENG for short, and virus definitions that all other Microsoft desktop anti-malware products share, including Forefront Client Security, Windows Live OneCare, and Windows Defender.
Before installation, MSE checks for the validity of the installed copy of Microsoft Windows. MSE requires no registration or personal information.MSE will disable Windows Defender, as it provides protection against malware, not limited to spyware and adware.
Using default settings, archived files are decompressed, and then scanned. File downloads and e-mail attachments are also scanned. Its Dynamic Signature Service attempts to better identify malicious files by checking for updates if an application exhibits suspicious behaviour. Before taking action against a suspect file, MSE prompts for user input. If no response is received in ten minutes, then the suspected malware is handled according to its default action, letting MSE determine what to do with the malware. System Restore points are created before removing found malware.
MSE automatically checks for and downloads virus definition updates which are published three times a day to Microsoft Update. Alternatively, users may download the updates manually from Microsoft Security Portal.
In February 2010, a rogue security software package calling itself “Security Essentials 2010” appeared on the Internet.
