How can I remove this even though Google is selected as a search engine?

Question

Browsers

Here, when searching for something, with a 50/50 chance, either this or Google comes out, I tried adwcleaner, but it didn’t help, please help

Answer 1

disable all extensions, but there are quite a few of them, if the problem disappears, enable one at a time until the problem returns.
you can still tweak the logs
