Please, don't tell people to do this. This way computers get infected. People should know that clicking in a random link posted by an anonymous guy on a forum page is one of the worst things they can ever do.
You're right that in general training them to listen to anonymous forum posts is less than ideal, but all in all I'd rather they have a working browser. As a side benefit they get to see posts like this that rightly point out you shouldn't trust strangers on the internet too much.
