I'm sitting here looking at the site and while I'm not "thrilled" with some of the changes have had only one problem "No Packets To Send" . It is very slow loading from my home page, but one other non-car site I use is as well.

My guess is that your computer has 'eaten' a virus or the registry is corrupted. As far as pop up, I use Firefox and they have an add-on called Adblock to dupm them.
