Strange problem with IE

Well, I have been having this problem for some time and can not figure it out. The problem is that, at times, certain graphics, ads, and pages won't be displayed.

For the graphics, some of them will have a missing space with an x in the top left hand, as if the graphics does not exist. For the ads and similar types, it will not be displayed and, instead, an "Action Canceled Internet Explorer was unable to link to the Web page you..."

Finally, for some pages, the page will just not be displayed. You get the usually error "The page cannot be displayed The page you are looking for is currently unavailable..." It only occurs in rare instances; it seems to be related to page redirects. For example, if I go to one of the ad listings in google, I always get that error.

I have the feeling that these are all related since they all occured at the same time. I ran Spybot, Ad-aware, and Microsoft Antispyware but that did not fix the problem and I am unaware of what actually started this problem. Any help or ideas would be greatly appreciated.
