Hi, Sorry if this seems very simplistic, but I want to be sure I'm not cocking things up. Until a week ago I was using a router, and I believed that meant I didn't need a software firewall. I used to use one but when I got the router I stopped. Last week my router broke down and so I installed Comodo firewall to cover me while the cable modem was connected directly to the computer. Today the new router arrived, though. I've installed it, and now I'm wondering whether I can switch Comodo off. Naturally I have AV software: I just want to be absolutely clear on whether I need a software firewall now that I've got a working router again. Incidentally, I have a Motorola SB4100 cable modem, and a Netgear WGR614 v.9 router. Many thanks for any help.
