Download Microsoft Security Essentials

Thank you for using our software portal. Downloading the required product from the developer's site using the official link provided by the developer to Microsoft Security Essentials below was possible when we last checked. We cannot confirm if there is a free download of this software available.

However, we must warn you that downloading Microsoft Security Essentials from an external source releases FDM Lib from any responsibility. Please carefully check your downloads with antivirus software. FDM Lib takes it upon itself to provide free download links and inform users when the developing company starts providing a version of Microsoft Security Essentials for direct download.
