Cannot remove Parabola theme from WordPress

I have installed Parabola on WordPress platform. I had activated infolinks plugin on this theme, but it didn’t support. So decided to remove Parabola theme and install another theme. I installed another and after logging out from wordpress it shows parabola theme in unorganized way. I need help if someone know how to fix this problem. My website is http://www.mitrawedsmohit.com
