safari acting hacky
I don't know if this makes sense, but here we go.
a while back I downloaded some youtube to mp3 downloader.
after downloading and installing it my safari restarted. and I disregarded it thinking it was some bug.
but now my safari one again shut down and without that error message you get.
and when I opened it again I found this weird thing on the toolbar(shown in image below).
anyone know how I can check if someone hacked my safari?
or maybe im just overreacting to some safari bugs.
Thank you
