Microsoft Defender: Comprehensive protection against viruses and malware for your Windows devices. A robust security solution included with Microsoft Windows.
Microsoft Defender is the built-in antivirus software component included in Microsoft Windows operating systems. Initially released as a free anti-spyware program for Windows XP, it has since evolved into a comprehensive security solution. It replaced previous iterations like Microsoft Security Essentials and now comes standard with Windows Vista, Windows 7, Windows 8, and later versions, including Windows 11. This integrated approach provides users with robust protection against malware threats directly within their operating system, simplifying the security process for everyday use.
