I have set the search engine to google, but every time I search from the bar it automatically searches by the yahoo search engine.
The Issue is produced every single time I search through the web bar.
Version 1.19.92 Chromium: 88.0.4324.152 (Official Build) (arm64)
Hello @pastorb
1)try to update your browser
2) go to brave://settings/searchEngines and click on the 3 vertical dot in front of google search engine then make it default
if that does not help try to disable all extension and see if it work fine or not
if it worked fine then the issue in one of your extension try to enable them back one by one till you get the one that cause the issue
hope that help and have a nice day 
none of those worked. I think it is some type of spyware.
This web address helped me fix it completely. It is a malware that attaches to your browser.
glad to know that you figured it out
well done and have a nice day
