Windows Defender is a Microsoft Windows anti-malware program. It was first made available as a free anti-spyware download for Windows XP, and later came pre-installed with Windows Vista and Windows 7.
Meanwhile, it has grown into a comprehensive antivirus application that is included with Windows 8 and subsequent editions, replacing Microsoft Security Essentials. Microsoft Defender lacks advanced security features such as a password protector, sandbox, or internet phishing checker when compared to another antivirus, yet it protects against malware installed on the computer.
Furthermore, Microsoft announced Microsoft Defender ATP for Mac for business customers on March 21, 2019, to protect their Mac devices from attacks on a corporate network, and Microsoft Defender ATP for Android and iOS devices a year later to expand protection for mobile devices, which includes Microsoft SmartScreen, a firewall, and malware scanning. When Microsoft Defender is installed on a mobile device, it has the ability to deny access to corporate data if it detects dangerous software.
