Just today, after I ran Ad aware, Spybot and Windows updates, Internet Explorer no longer works. When I click on the icon, the hourglass runs for about 10 seconds, then disappears and nothing happens. I then downloaded and ran Spy Sweeper, but still no luck. Help!

I am running Windows XP, Home Edition, and IE 6, sp1. Oh, and this is my first time posting, so please excuse any ignorance.

I ran Hjt:
