Microsoft is finally taking action against scammy optimizer apps in Windows. The company announced on Tuesday that it’ll be rolling out a new update to Windows Defender that will block and potentially remove such apps.

In a blog post, Microsoft said that regular Windows users often use free optimization software to check for errors on their computer, but these apps later force them to upgrade to premium versions in order to protect their device against the issues. Some of these apps even mislead users by exaggerating a problem and use tactics such as a countdown timer to scare users and force them to purchase premium versions of the tool. Apps that also try to get users to sign-up for newsletters, or require users to take surveys will also be penalized, notes Ars Technica.

As part of the updated set of criteria for malware and unwanted software in Windows, Windows Defender will detect such apps and remove them from the user’s device to protect them from further damage. “Programs must not display alarming or coercive messages or misleading content to pressure you into paying for additional services or performing superfluous actions,” Microsoft said. The update will go live on the 1st of March.

These type of apps aren’t a big deal amongst technical or power users, but you’ll be surprised to see how regular users can get easily fooled by these scammy crapware. Needless to say, Microsoft should have taken action against these apps ages ago, though it’s never too late.
