in reply to A perl personal firewall?

Thanks, yes, let us stay on the technical side of this question since there is no correct answer for the social side.

AIM actually can detect open port and switch to that port. Once I opened only outgoing port 80 and 53(DNS), and I found later AIM was using 53.

I think the filtering needs to be on layer 7, maybe something like snort.

    Layer 7 is the application layer. Snort is an Intrusion Detection System that also does packet logging and digs at least down to layer 4 so I am having trouble following your logic.....

    If what you mean is that you want a daemon to kill off AIM if it starts then you could simply use Win32::Daemon from roth.net to run a search and destroy based on Win32::KillProcess or similar.

    cheers
