As ransomware and spyware increase, users need to keep their systems up to date and be vigilant,media reported. Windows 10 has many security features to protect your PC, and Windows Defender is constantly updated to enhance protection against new threats. With the arrival of Windows 10 May 2020 Update, the next major feature update for Windows 10, Microsoft has introduced a new security feature to protect users’ PCs from potentially unwanted apps.
It is understood that Windows 10 users often download to bad-looking applications when searching the Internet for free versions of software. Many reputable applications are bundled with potentially unwelcome applications (PUAs), which, if run, could slow down Windows 10, insert ads, and even change browser search engines.
In response, Windows 10 May 2020 Update introduced new protection features in Windows Security programs that provide protection for potentially unwanted applications (PUAs), but are currently not enabled by default.
Enable PUA protection in Windows 10
To block applications that might not be needed on Windows 10, follow these steps:
Open the start menu and search for settings;
Go to Update and Security in Settings;
Look for app and browser control pages and open reputation-based protection settings.
Once this feature is turned on, Windows Security applications step in and block adware, cryptocurrency miners, and other unwanted spam bundled when downloading free software.
In addition, Windows Security applications will allow users to manage PUA protection and block or allow applications, downloads, or both. For Microsoft Edge users, Windows Defender scans when the PUA downloads in the browser.
PUA protection is also built into Chrome-based Edge, but needs to be enabled manually:
Open the Edge settings and go to the Privacy and Services section;
Scroll down to the service and enable Masking applications that may not be needed.
Microsoft says Windows Security can still detect it and block it if it has been downloaded or installed from a different browser.
