These adwares are usually found in freeware software bundles, they look harmless until they are installed. Microsoft calls them potentially unwanted application(PUA). Microsoft has added a new feature to the presently pre-installed Windows Defender but only announced it for Enterprise users.

The good news is, the new opt-in feature for enterprise users in Windows can spot and stop PUA in its tracks.

But since Windows comes pre-installed with Windows Defender home & business users can enable it to block any future adware installations to protect your precious Windows system.

WHAT IS PUA AND WHY IT SHOULD BE BLOCKED?

PUA are Potentially Unwanted Applications which are packed in software bundles without the knowledge of the installer. They are harmless on surface but can potentially be the source of letting in malware to your system which sends your information and your PC usage stats & behaviour which can lead to phishing and targeted ads based on your activity.
