PuA apps are defined in the blog post as creating additional ads that invoke resources to mine cryptocurrencies, applications that serve other software, and applications that the AV industry considers to be reputable.
This feature is turned off by default and can be enabled by going to the “…” menu in the upper right corner, Settings and Privacy and Services, and then scrolling down to the service to enable Block potentially harmful applications. It is important to note that microsoft Defender SmartScreen should also be enabled for this feature to work.
