The Dink Network

It's happened again, I can't believe sites like this can get away with highjacking your home page! There I am innocently reading the news when a site mentioned caught my eye. I went to that address. I wanted to see it and instead something else appeared that was totally unrelated. When I clicked to close the window, another site appeared. Now it's my home page!! How do they do that?

Edit: Can't remember how to get my home page back. Help please. Tx

Edit once more: Never mind. Got it. Now I'm going to getright and buy "geek superhero".
