Hmm, i never have bothered with a firewall. whats the point? If a hacker really wants to break into my computer to steel my pron then he will no matter what i am using. If you are dfumb enough to use banking online and keep personal info like pins number and passwords then thats just insane. I agree with virus software and spyware tools. I use NAV corp and i run adaware PRO - spybot and Xsoft pro. Other than that, you have NO chance of a stopping a hacker at all. Unless it a script kiddy then the tool he is using will simply do a scan for what ever he is looking for and then leave to the next victim. Why spend your entire time online freaking out.
