Microsoft Defender Antivirus
Microsoft Defender Antivirus (formerly Windows Defender) is an antivirus software component for Microsoft Windows and mobile. It was first released as a downloadable free anti-spyware program for Windows XP and was shipped with Windows Vista and Windows 7. It has evolved into a full antivirus program, replacing Microsoft Security Essentials in Windows 8 or later versions.
In March 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, it 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.
As of 2021, Microsoft Defender Antivirus is part of the much larger Microsoft Defender brand, which includes several other software and service offerings, including:
Microsoft Defender Antivirus provides several key features to protect endpoints from computer virus. In Windows 10, Windows Defender settings are controlled in the Windows Defender Security Center. Windows 10 Anniversary Update includes several improvements, including a new popup that announces the results of a scan.
In the Windows Defender options, the user can configure real-time protection options. Windows 10's Anniversary Update introduced Limited Periodic Scanning, which optionally allows Windows Defender to scan a system periodically if another antivirus app is installed. It also introduced Block at First Sight, which uses machine learning to predict whether a file is malicious.
Integration with Internet Explorer and Microsoft Edge enables files to be scanned as they are downloaded to detect malicious software inadvertently downloaded. As of April 2018, Microsoft Defender is also available for Google Chrome via an extension and works in conjunction with Google Safe Browsing, but as of late 2022, this extension is now deprecated.
A feature released in early 2018, Windows Defender Application Guard is a feature exclusive to Microsoft Edge that allows users to sandbox their current browsing session from the system. This prevents a malicious website or malware from affecting the system and the browser. Application Guard is a feature only available on Windows 10/11 Pro and Enterprise. In May 2019, Microsoft announced Application Guard for Google Chrome and Firefox. The extension, once installed, will open the current tabs web page in Microsoft Edge with Application Guard enabled. In April 2024, Microsoft announced that Microsoft Defender Application Guard will be deprecated for Edge for Business. The Chrome and Firefox extensions will not be migrating to Manifest V3 and will be deprecated after May 2024.
Controlled Folder Access is a feature introduced with Windows 10 Fall Creators Update to protect a user's important files from the growing threat of ransomware. This feature was released about a year later after the Petya family of ransomware first appeared. The feature will notify the user every time a program tries to access these folders and will be blocked unless given access via the user. Windows will warn the user with a User Account Control popup as a final warning if they opt to "Allow" a program to read Controlled Folders.
