First: If this is XP you're speaking of, then install SP2 - it has a new version of IE which can enable/disable these "trickers" add-ons. If its not XP, then get Maxthon shell for your current version of windows, after installing IE6SP1. Maxthon is very quick, allows you to disable those add-ons, very well configurable, has tabbed browsing, and finally it can be made the default browser into which all clicked links open. The fact that maxthon actually runs the IE engine is a major benefit, since it will be compatible with all sites!
