Someone Please Explain

Robin said that when she tried to access webpage she got instead an ad. Thinking it was something hidden in my template I deleted my template and went with blogger's template. Today I went to Starbender's blog, I clicked on the link like I normally did and went to her page but only for a brief second before I was redirected to the following page http://earn-your-degree.com/degree/index.php?ext=70000&fil=all.

What is going on? When I used the back button I was once again redirected to http://earn-your-degree.com/degree/index.php?ext=70000&fil=all. Then I went back to my blog and clicked the link for Starbender and guess what it did it again.

Would someone please explain what the heck is going on?

Thanks
