Microsoft Defender Antivirus is an anti-malware component of Microsoft Windows. It was first released as a downloadable free anti-spyware program for Windows XP, and was later shipped with Windows Vista and Windows 7. It has evolved into a full antivirus program, replacing Microsoft Security Essentials, as part of Windows 8 and later versions. On March 21, 2019, Microsoft announced Microsoft Defender ATP for Mac for business customers to protect their Mac devices from attacks on a corporate network, and a year later, to expand protection for mobile devices, announced Microsoft Defender ATP for Android and iOS devices, which incorporates Microsoft SmartScreen, a firewall and malware scanning. The mobile version of Microsoft Defender also includes a feature to block access to corporate data if it detects a malicious app is installed.
