Microsoft may be working on a new Microsoft Defender application for Windows 11. According to a leaked screenshot (via @ALumia_Italia and, the app is still in development, carries the “Microsoft Defender Preview” label, and it’s codenamed GibraltarApp.

It’s unclear how the company plans to integrate this application, but currently, the Microsoft Defender Antivirus can only be accessed through the Windows Security app. So, either Microsoft intends to separate the antivirus from the Windows Security app or replace the app with a new app called “Microsoft Defender.”

According to the Deskmodder report, this is a Windows Presentation Foundation (WPF) application that uses XAML and WebWiew2, and it is not a web application.
