Personally I would NEVER download a Beta program unless I know enough about computers not to need help. Why not uninstall it and wait until it is on general release, and bugs have hopefully been ironed out by people who are good at that sort of thing?
SOLVED. Actuslly, it's fast,AI RoboForm, McAfee Site Advisor Plus, Web of Trust (W.O.T.) and AdMuncher all work fine with it. It's actually quick, too. I Binged and Googled and found some lists on a Microsoft site here's the address for anyone interested. http://ie.microsoft.com/testdrive/Browser/TrackingProtectionLists/Default.html
