freshbeyond is an extension in safari that I cannot uninstall or delete. is this a spyware. what is the solution

I understand that Safari has an installed Extension that you do not want and cannot remove. Is that correct?

Even though it does not address that specific problem, please read Removing "Search Marquis" / "Search Baron" / etc on your own - Apple Community, and post the three screenshots it describes in a reply to this Discussion. One or more files on one of those three folders may be responsible for causing that Extension to appear.
