Microsoft develops software not only for its own Windows operating system, but also for other popular platforms, including Android and macOS. In the Microsoft Store preview of Defender, two of these systems are mentioned.
The Microsoft Store has a preview of Microsoft Defender listed as a Microsoft product. The description of the program says: “Security, simplified. Microsoft Defender is your personal protection against digital threats. Protect your devices on [various] operating systems, including Windows, macOS, and Android”. Windows Defender is an antivirus program for Windows PCs that has grown from a mediocre product to one of the best solutions on the market. And Microsoft seems to want to replicate its success on other platforms.
The Italian website Aggiornamenti Lumia has published promotional slides for Defender, which indicate that the program can be in use to scan files on Mac computers and Android mobile devices. The slides also show the “Web Protection” feature – it may indicate that the antivirus will also scan web pages and evaluate their safety.
Many Microsoft products and services are already available on multiple platforms: Android has Bing, Edge, Office, and Teams enterprise messenger. Office is also available for macOS. Therefore, it is possible that the proprietary antivirus will also become cross-platform.
