Ask HN: What security software/configurations do you use?

For five (I think) years I've used nothing but ZoneAlarm, no antivirus, no spyware-removal-tools. And - as far as I know - I've never had a single virus/trojan. Being a geek surfing the net is something i do every day, and a lot of it, but my belief is that as long as you're carefull, you're OK.
