You didn't say if you were using IE or Foxfire or whatever. For IE 7 you can go into the tools>accessibility button just to the right of the fonts button. It will allow you to "ignore" website fonts. Or you can setup your own .css stylesheet to override websites.
Another possibility is to uninstall the font if your not using it. Then the webbrowser will choose something else.
Foxfire also has the ability to set fonts under the tools>content tab/buttons.
