i realize that having a firewall is a way to protect my compuer against potential hackers, but i've always wondered why i should have to protect my computer in the first place if i don't have any "sensitive" information on it. i don't have work documents on my computer, and i don't keep any records on my computer that i think would be of any interest to anyone. i know there's people out there that would hack my computer just to hack it (and yes, i have a firewall on now) but i was just wondering how "worried" i should be about the consequences of someone getting into my system.
