Ads pop-up

Hi, pls I need your help; ads keeps popping up on my screen and I think it has to do something about browser but I tried to locate the app and uninstall it but didn't find anything. Any advice?

Sounds like your browser has picked up a Potentially Unwanted Program (PUP). This type of Adware or Malware can usually be found and removed by scanning with ADWCleaner and Malwarebytes (free). Use ADWCleaner first.

Thanks so much, it worked
