I have no wireless I run off a wire.. (Hate wireless when gaming)
I have no Firewalls or anitvirus because I don't believe it them.
I haven't had a virus or anything for years.
Before anyone asks "Go scan your harddrive" or "How do you know".. All I can say is.. I just do.
I can "sense" if something is wrong or different on my PC.. I know the whole thing inside out..
I dare someone.. Just use windows firewall and a hardware firewall on the router.. you will be fine!
(depends what kinda websites you go on though)
