Better yet, why not install Google Chrome and replace their Internet Explorer link with a link to Google Chrome? Just make the link have IE's icon so that they don't wonder where the internet has gone.

They will marvel about how you "made their internet faster." I like to make it even easier for people by making two different links: one called "Internet" which takes them to Google, the other called "Email" which takes them to their web email. The results are instant simplification, security improvement, and general betterment of the web by migrating more people to the Webkit rendering engine.
