I've been trying to find a resolution to this problem for a bit now to no avail. I have been surprised at the number of similar problems that have been solved, and some not, but none of these fixes has worked for my situation. I have registered a bunch of DLLs, set my security to default levels, run spybot and disabled my firewall without relief. The symptoms are that I cannot log into many sites, including hotmail, all of which simply return a blank page. I also cannot access Windows update. I believe that this problem started when I uninstalled the Yahoo toolbar, which was causing my computer to repeatedly crash. Unfortunately this problem also seems to be preventing me from downloading the latest yahoo toolbar version, which I was hoping would restore some lost or damaged dll file or something (I really don't want the toolbar).
