I have the android version of that browser, and have never had any problems with it. I don’t know enough to advise as to whether you have malware or just an incompatibility issue.
I use Brave on my Android, I like it well enough. I can’t be certain, but the pay trace thing might be adjustable in one of the settings. As was mentioned, you can donate money to offset the revenue lost by websites as a result of the blocking of ads. Your best bet is to look at the Brave documentation. I don’t believe the browse4 is a malware, bit that doesn’t mean it can’t have been placed into a new wrapper with such a pay thing added into the wrapper. Much depends on where you downloaded the software from.
My only issue with brave on my phone is that it seems to have difficulty with word wrapping and text size working together. Other than that, it works super for me. I can even play vids without the advertising some sites like to include with thei4 vids.
Do some research.
