Yahoo somehow installed as my default browser and I can´t get this back to normal

OK so the other day I was watching on some pages, when all of a sudden I clicked on something that I have shouldn´t and it opened a site Mackeeper. The installer app Mackeeper some downloaded how on my MacBook and now everytime I open Safari, it goes to the Yahoo Search page and it does the same thing when I try to open a new tab or a new window.

So if someone could help me I would appreciate it a lot, I really look forward to Yahoo and now I hate even more thanks for that.

Turn over some and test.
