I have been browsing the internet trouble-free for the past several days, but yesterday after I restarted, I could no longer access web pages through Internet Explorer. Mozilla Firefox is still working fine, but every page I attempt to visit with IE returns the standard "The page cannot be displayed" message with "Cannot find server or DNS Error" at the bottom. I updated SpyBot and ran a couple of scans, which found a few items, but that didn't fix the problem.

I urgently need to resolve this, since I'm a consultant working on-site and Firefox isn't compatible with the site(s) I'm working with.

Here's my Hijack This log:

Somehow the connections settings were changed, so internet explorer was trying to go through a proxy server (port 80). I definitely did not change this myself, but I was able to remove the proxy setting with no difficulty.
