I should have posted about this back when it first happened.
When I first got my computer, Internet Explorer was working fine. I only used it long enough to get Firefox, but occasionally I'll open a page in IE if I'm having a plugin problem that I don't feel like trying to fix in Firefox.
I don't know if this was the problem or not, but once I tried to upgrade it to IE7...it stopped loading pages entirely. The browser itself will open, and I can interact with the toolbars and such, but trying to load any page results in an unending blank screen with "Connecting..." showing up. I can hit the cancel button to get "Navigation to the webpage was canceled" and try typing in another site, like Google, but the browser acts like it's trying to load the page but never gets anywhere. The only pages that IE can load are HTML files that I create/save to my computer first.
Of course, Firefox can load Google just fine for me. I've tried reinstalling IE6 but now that is giving me the same problem of pages not loading. I've tried searching on Google but I don't seem to find anything that'll help. AVG doesn't see any virus, either. Has anybody else experienced this problem and knows how to fix it?
