Windows Defender is a free antivirus software program developed by Microsoft that is designed to protect Windows operating systems against viruses, spyware, rootkits, and other malicious software. It is included in all versions of the Windows operating system since Windows 8, including Windows 8.1, Windows 10, and Windows Server 2016.
