Windows 10: How to get rid of Yahoo pestilence?

Hi guys (and gals),
Google is my default homepage, but when I type in a search term, I get the Yahoo Search results page. I don't want Yahoo Search!
I removed it from Chrome Settings (it was there right under Google but not as default), did a restart, and the Settings overview says "The default browser is currently Google Chrome".
I also looked into the Registry. No Yahoo there, or any other unfamiliar file.
Control Panel: not in the Programs list.
I tried Malwarebytes and get a Clean result. I downloaded another one, but Norton intercepted it as Dangerous.
Can you tip me for another removal tool?

I don't use Google Chrome but here are instructions for setting your search engine in Edge
Set your default search engine - Computer - Google Chrome Help

Here's another one Make Google your default search provider – Google

I would imagine you will see Yahoo as your search engine, but once to change it, Yahoo shouldn't be bothersome anymore

I did all that, MAMC.
Yesterday I discovered Yahoo in the Chrome settings and removed it. All there is left now is the Google engine, and it's marked Default. I don't know if Edge has its own config for this, sometimes a popup asks me to make Windows explorer my default browser, which I click away.
I replaced the old shortlink in the Bookmarks bar for a new one (Google Search is not my standard homepage), but to no avail. But mind you; Yahoo pops up only after I type a search term in my Google Search. That's not okay. So I smell a little hack.

Something fishy here. Try a scan with AdwCleaner.

Bree, that's what I did. Must admit, it was the trial version.
Okay, I'll give all options a go.
