Trying to find out what’s causing the modification of results, changing the search engine doesn’t show us the answer. If there is an issue within his user profile, changing the search engine won’t resolve the issue.
It could have been a Virus of some sort… They are basically there to redirect you to a specific result in this case it is JAVA. Which is very dumb, but still I think he has some problem in his browser…
The perfect way would be to wither create a new profile or the best option is to just reinstall Brave. Changing Search Engine doesn’t do anything I know but there is a small chance that the Virus works only in Google, so I asked him to change the Search Engine.
