I've been hit with a Trojan virus today that only applies when I'm running Firefox.

I've been hit with a Trojan virus today that only applies when I'm running Firefox. I've been advised that resetting my browser (or even doing a 'factory reset') will remove the problem but there doesn't appear any way of doing so. How can I do this to hopefully remove the Trojan? Trying to 'Remove the virus now' in the Firefox pop-up doesn't work.
