Removing main widgetbox

I tried to install a widgetbox onto my blog that I had created. I have installed it on my blog down the right side of the page. But now, every time I go to my blog, it has the main widgetbox option box on it with the options of embedding code or installing on other blogger sties. I have attached a picture to show what I mean. How can I have this widgetbox removed from my blog site?

Thanks for your assistance.
