Not sure why my last thread was closed. It seems that the general consensus is that I don't need antivirus. What about addon firewalls though? The community seems divided, and I think I'll play it safe with a firewall, and seeing that I will be visiting adult sites and online banking, I'd like to be well protected. I've learned about Little Snitch (for outgoing connections), WaterRoof and NoobProf (for incoming connections). Can I run Little Snitch with either WR or NP? Will they interfere with each other?
