What’s the right thing to do when you see the fraud information?

Actually, the scam adverts are not displayed in the web browser. Instead, they are included in the apps that are built in Windows 10. That’s why the browser-based ad blockers are useless.

So, Microsoft’s answer is: ignore the messages directly and close the tabs, webpages, as well as the apps that contain malware. Remember to not open the applications in which the fraudulent advertising campaigns are displayed.

For the advanced Windows 10 users, they can also consider the DNS-based ad-blocking solution or install some tools that are able to block the app ads at the network level.

There’s nothing else you can do except waiting for Microsoft to kick out the fraudulent campaigns and the corresponding publishers.
