I have what might be a stupid question...

I'm not used to PCs anymore - Mac guy - but I'm planning on getting a PC soon. Should I buy Norton anti-virus to go with it? I can get it for a decent price, so I ask the windows people, how big is the risk? Does Norton get everything you don't want? Or are there other things that will affect security more, like choice of browser, firewall, or e-mail client?

Thanks in advance.
