Don't beat yourself up mate.

Lessons about security should be learned, but Google is complicit in this fraud.

Most people don't expect hijacked search ads with malicious advertising. I've personally witnessed well over 200 intrusions stem from malvertising. Just be happy this didn't lead to your org being ransomware'd.

As said in the comments, use Unlock Origin, and most importantly, move away from Google. Try DuckDuckGo as the default.

Better yet, install Librewolf (built in AdBlock plus DuckDuckGo set to default)
