Oh yeah, of course.
Turns out Genieo was the problem, so I simply followed the steps from The Safe Mac » Adware Removal Guide : Genieo, the link has been posted above. Make sure to follow the steps as accurately as you can, because there's a chance that you may break your Macbook, but they also provide a way to recover from that.
Read everything properly, or you'll be putting yourself at risk. Thanks again
