Must be something like what you said Saint. When I went to the homepage (havent been there in years...) and looked at what page source I could get, didnt see any QT stuff, also, task manager isn't showing QT loaded when visiting the homepage.
OP, I would suggest trying it with a different browser first and also check your file associations. Also, run your browser in "safe mode" (firefox has this mode, accessible in the program menu under mozillafirefox/firefox(safemode) and see if it still comes up. What browser are you using?
