Want to get rid of doubleclick? This was posted on another board:
"In IE go to tools, select internet options. Select the security tab. Click the restricted sites icon and then the sites button. Add this website to zone.
*.doubleclick.com then hit the add button.
*.doubleclick.net then hit add and ok on out.
