Microsoft has added a new feature to the upcoming 2004 release of Windows 10 to extend the protection level of the built-in Windows Defender antivirus.
In addition to the default malware scan features, the Windows security application can also detect potentially unwanted apps (or simply PUAs).
The term potentially unwanted apps or simply PUA usually refers to unwanted grouped applications. These applications can increase the risk of your device being infected by malware and fill your system with applications that you do not need. The potentially unwanted apps include many types of software. They display ads, persistently invite you to pay for services you do not need, etc.
Microsoft uses specific categories to classify software as PUA.
Advertising software: Software that displays ads or asks you to respond to queries for other products or services in completely different software. They contain software that inserts ads on web pages.
Torrent Software: Software used to create or download torrents or other files used specifically with peer-to-peer file sharing technologies.
Cryptomining Software: Software that uses your device's resources to extract cryptocurrencies.
Commitment software: Software that offers the installation of other software that does not have a digital signature from the same company. Also, software that offers the installation of other software designated as PUA based on the criteria described in this document.
Marketing software: Software that monitors and transmits user activities to applications or services for marketing research.
Avoidance software: Software that tries to avoid detection by security products, as well as any software that behaves differently in the presence of security products.
Malicious software: Software that identifies trusted security providers with their security products.
The Windows Defender so with the upcoming version of Windows version 2004 will have built-in protection against such applications. Previously, you had to apply a tweak to the registry to enable this feature.
With the new version of Windows, Microsoft also brings a new GUI to enable or disable the new feature much more easily. It is worth noting that Microsoft Edge uses the same technique to detect PUA when downloading files from the Internet.
