I have followed these steps and didn't find anything untoward. Having said that, I disabled one or two things that didn't look necessary.

The pop up ad at the bottom of the page seems to have gone now. And the annoying drop down menu on the right of the page hasn't appeared. But there are still links in posts. I can live with that as long as the pop up ad is gone. I guess I just need to find what is causing the links.
