What about good firewalls? Most people think that just a good AV will help but what happens when you are on a wifi connection, one that might not be your own so you have no real line of defense?

just installing an anti virus wont help out for the full protection! You must have an firewall also which have the capability of blocking malicious attacks and protecting your from it. Firewall also have the control of Local Traffic, you do not have to worry about outside (Internet) security.
