Does anyone know how to fix this redirecting yahoo thing I accidentally downloaded?

I downloaded a wrong link on the wrong website and I’ve had this redirection for 6 years on chrome. Sometime Firefox works, but I have tried numerous softwares to delete and find the problem. Nothing seems to work, but I haven’t taken it into somewhere yet. Anyone have a clue on how to fix this redirecting download link? This is a MacBook 10.13 submitted by /u/caniplant [link] [comments]
