For reasons too annoying for me to go through again I have decided to remove Norton Internet Security. But I would like some unbiased/unhysterical advice on the subject of internet security. Basically I would like to know how much of it I need? I use Firefox and Thunderbird, so NIS never really integrated with them anyway. I have a router with a firewall and will be downloading ZoneAlarm as a software one. I have Ad-Adware and will also be downloading some freely available anti virus software. Is this enough? How much do you need?
