Google Browser no longer in Chrome

W11 26H2

For 3rd time Browser has stopped using Google and switched to Yahoo, even though previously deleted Yahoo
All searches I try for help tell me to select Goggle under settings - I can't as its not there as an option.

How do I add Google back into Chrome & stop it being changed.

Your browser is likely infected with a browser hijacker or a Potentially Unwanted Program (PUP) that forces your searches back to Yahoo. Just deleting Yahoo or changing your default search engine is not enough because the underlying malware or rogue extension automatically resets it. What extensions do you have?
