Westell 6100 - modem/router. - NAT features and hardware firewall. ZoneAlarm Security Suite 6.1 - decently light little thing. Only freezes up when I crash it. Prev1 R - Not much to say about this. I rarely see any prompts even on Pro unless I'm installing. On Demand BitDefender Free Ewido MSAS, Spybot, AdAware - When I feel like I have 3 hours to kill. And of course, safe surfing with Maxathon.
