Spysweeper & Norton are programs. A router is an electrical device that forwards data along networks. It's a piece of hardware. So have a look at all the stuff that plugs into your computer (mine is a modem & router combo that looks like a flat black box).

Lots of routers cause firewall probs, that's why it's so important to find out what yours is. If you're not sure, get your Dad to help you look. He might have a manual for it somewhere & that'll have the brand & model in it
