So, I downloaded " Safari AdBlocker" from the Apple Store (http://www.apple.com/downloads/macosx/internet_utilities/safariadblocker.html) and it didn't go well. It installed but nothing changed, this is not the first thing that I have installed so I don't think that was a problem, I just felt odd about it,so I uninstalled it. Today I had some pop-ups. Can this AdBlocker be the cause. I should ad that it's not a lot of pop-ups, but some. This is my first Mac so I don't know what I'm doing and I don't know what I'm asking. Any help would be appreciated, thanks.
