When I purchased my new PC it came with a whole host of crapware that I didn't want. Most of this could be removed but one piece of software remained, an extension for IE that brought up a Dell search page whenever a website failed to load. I've never tried to get rid of this because it's never caused too much harm but today it began interfering with my work so it was time to get rid of it. IE7 makes it pretty easy to disable pointless or dodgy add-ins. If you have the same problem as me, go to Tools/Manage Add-ons/Enable or Disable Add-ons and disable CBrowserHelperObject object. No more 'helpful' Dell search page, yippee!
