The prevalence of malware, ransomware, and spyware has increased over the past two months, so you must be especially careful to safeguard your data. Microsoft prioritized security patching after working overtime to address them.

Additionally updated constantly, Windows Defender now offers better defense against fresh threats. Additionally, Microsoft added a new security feature to Windows 10’s May 2020 Update that will shield your PC from potentially malicious programs on both Windows 10 and Windows 11.

The first guideline of Internet security is to never download programs from any free source with a bad reputation.

That’s because many of them are bundled with potentially unwanted applications (PUA), which, if used, could cause pop-up advertising, system slowdown, and unexpected changes to your browser’s search engine.

With Windows 10 May 2020, Microsoft adds a new reputation-based protection function to the Windows Security app. The new security feature provides defense against PUAs; however it is not currently turned on by default.

How can I block potentially unwanted apps on Windows?

Follow these procedures in Windows 10 and Windows 11 to enable PUA protection and block them:

    1. Reputation-based protection will appear in the search results once you type Reputation into the Windows search box.
    2. After that, select Reputation-based protection options and App & browser management. Now, click the button to enable the setting to block potentially unwanted apps, as seen in the image below.

The Windows Security program will begin blocking adware, bitcoin miners, and other unwelcome scamming apps as soon as you enable the option, which can be included with free software downloads.

Using the Windows Security app, you may handle PUA protection and restrict or allow programs, downloads, or both. It’s good to know that this feature is also present in Microsoft Edge browsers, enabling Windows Defender to do an automatic PUA scan. At the same time, the program is downloaded in the browser.

You must manually enable the PUA protection for Microsoft Edge based on Chromium. Simply to Edge settings and navigate to the Privacy and services area. Then click Services and turn on the option to block possibly unwanted programs.

We really attempted downloading several well-known dubious adware apps to test it out, but it isn’t yet functional.
