Not trying to make your day worse but you either got hacked or are doing nasties on there on purpose.
I will assume that you have been hacked and someone has injected something into your page. I do not think that what I am seeing came from my computer but it is a possibillity so I am scanning right now to see if I somehow got hit.
But when I hit the up arrow icon at the bottom of the page to go to the top of the page I got a nasty FBI bullshit popup.
If it is from a hack you need to get secured, if you did it yourself you need to get rid of it.
