I don't know what you expect mIRC to do. I don't even know how you make a connection between IRC and 'hackers'. The only way that people get 'hacked' over IRC is by typing in what any random person tells them to type or by clicking links given over IRC (although the actual 'hack' occurs because of insecurities in the user's web browser - take it up with Microsoft). The only other way people can possibly be 'hacked' with IRC is if they use a server which doesn't mask hostnames, so that any user on IRC can see any other users host. Even then this isn't a security risk in itself provided the system is secure, and it isn't exclusive to IRC since if you do anything over the Net your hostname/IP can be *seen* by half a dozen other computers at any given time.
