The computer giant's own built-in antivirus software used for Windows 10 will removed programs pressuring users "into paying for additional services or performing superfluous actions".
Barak Shein - who is part of the Microsoft Windows Defender team - explained in a blog post: "There has been an increase in free versions of programs that purport to scan computers for various errors, and then use alarming, coercive messages to scare customers into buying a premium version of the same program.
"The paid version of these programs, usually called cleaner or optimiser applications, purportedly fixes the problems discovered by the free version."
Commonly known a scarware, the software will supposedly optomise your registry or vow to speed a machine up.
However, Microsoft sees this apps as "problematic" for regular Windows users, meaning its antivirus program will classify them as "unwanted software" to be removed.
The move to get rid of them will start on March 1, while developers can test their own apps at the company's Windows Defender portal.
