What is 4KMovieSearch?

The Malwarebytes research team has determined that 4KMovieSearch is a search hijacker. These so-called "hijackers" manipulate your browser(s), for example to change your startpage or searchscopes, so that the affected browser visits their site or one of their choice.
This particular one changes your default search engine and adds Search Recommendations.
