(Adware.Ecobar) -> Quarantined and deleted? What's next?

Greetings!
Well, here I am again with these new fresh, nasty things. It stays in my Quarantined list of malwarebytes antimalware. What do I do with them? Although scans says quarantined and deleted successfully. it is shown on my Quarantine list. Were they already deleted or I have to delete them? Do I delete them using Delete or Delete all the Quarantined interface? Perhaps, I don't have to do anything?

I have more information on my previous post. Now, when I restart my Computer malwarebytes is popping up(before even icons appear on my desktop) and asking me whether I want to make changes on my hard drive, I click no. Does it want to scan system before everything else is loading?
