A browser hijacker is an unwanted app that closely resembles a browser extension but the main difference is that most hijackers don’t really benefit the user in any way and instead simply obstruct their browsing experience with different changes in the browser.
If your browser is showing you a lot of ads and is frequently getting you redirected to different sites without you wanting it, then you must have a hijacker on your computer. “Your Browser is Managed by Your Organization” Mac popup
