Sims 3 uninstall problems?

I'm trying to uninstall Sims 3 from my computer. It says that it's successful but when I look into Program Files, it says that Sims 3 is still there taking up 5.66GB on my computer. My game has been having huge problems. Like when I load up my family it shows no people, none of their icons, and it says that I have $0. What do I do? I just want to play my game happily. I had World Adventures, High End Loft Stuff, Ambitions, Generations, Late Night, and Fast Lane Stuff. I torrent my sims games. What do I do?Sims 3 uninstall problems?
