Damned quicktime

Hey all, I seemed to have accidentally downloaded a quicktime add on to IE, and I can't figure out what files to delete to get rid of it. Whenever I click links for certain media files they open embedded in the browser in a quicktime box. I'd much prefer everything to open with WMP6.4. I went into WMP to set everything to be run with it, but no luck. Then I uninstalled QT from my computer. No luck again, it must be hiding somewhere else. I looked in the downloaded program files folder, but can't make heads nor tails of whats in there. I'd delete everything, but I've come to love this google toolbar.

TIA
