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

MacBook Pro 15", macOS 10.12

Force Quit Safari ( command + option + esc keys).Then restart Safari holding the Shift key. If you still have problems Empty Caches (Safari menu > Preferences > Privacy > Remove all website data. (This will also remove history if you do not want to remove History open Safari Preferences > Advanced and check mark “Show Develop Menu” then choose “Empty Caches” from Develop Menu ).


Then go to Safari menu > Preferences > Extensions and check there. If there is an extension delete it.


If the problem persists then download and run Malwarebytes. Malwarebytes was developed by one of our own colleagues here in ASC and is about the most proven anti-malware software for Mac.
