Agreed, but what really bugs me is this:

Emacs has to use TCP/IP to look for an XServer, but the best it can to is look at 127.0.0.1 and then $DISPLAY. Sooooo, assuming that both are on the same machine, why is McAffee 
detecting an attempt to get to the Internet? Shouldn't they both resolve to the LAN? Unless McAffee/Norton and the ilk monitor the TCP/IP stack and put up "messages" before the 
destination is decoded, assuming the worst?
