Keep PowerBook muted?

[intent]

Today in class some stupid Flash ad un-muted my PowerBook and blasted some ****** music. Since then I've used SafariStand to load plug-ins manually, but I'm still scared. Is there some way to make sure the PowerBook stays muted?

Thanks.

Hit the mute button

I don't believe a Flash ad can adjust your system volume.

That being said... don't browse the internet in class!

Or plug some headphones in (but don't wear them).
