The Google Play Store is often found to have Android apps that carry mining scripts, and it’s often no surprise to see such messages. The Microsoft Store is a bit better, all applications need to be reviewed by Microsoft auditors. But even so, the Microsoft Store still has applications that carry mining scripts, and these currently problematic apps have been removed from Microsoft.
The application in question is also a UWP application, so it can be run directly in Windows 10 or even Windows 10 S mode. The Microsoft Store doesn’t provide update dates or downloads, so there’s no way to tell how many users are affected.
Microsoft has removed all related applications after receiving a Symantec notification, but Microsoft has not issued an official statement on the matter and it is unclear about the details.
