I submitted this in general but just found this area which seem more appropriate. the search yahoo amlware appeared suddenly in both Chrome and Edge when I try to search for something. Avast can’t see it apparently. Anybody know how to get rid of it. There is nothing recnt on this and I have Windows 11.
Have you tried clearing broswer cache?
Also disable any browser add-ons/extensions one by one to diagnose if was one of them.
Look out for any add-ons/extensions you are not expecting to have.
