How to get rid of inappropriate ads and pop-ups from my computer?

I just got a new computer and I installed Google Chrome, well now, I get these really weird annoying sex ads on the side of my computer screen, I also get iphone game pop-ups and other stuff. I wanted to know how I get rid of these with out buying any new software or downloading anything.
