Norton Firewall Issues
After the recent Snow Leopard update (10.6.3), upon restarting my computer, a window came up apparently from a Norton product (I think it was the Firewall, though I am not sure), asking whether to allow Finder to have connection to something called "vapornet" that purported to be from princeton.edu (where I attend school). Upon ignoring the window (neither canceling nor okaying it), another (I think, identical) one popped up, which I then allowed. I later emailed the school's tech people who said that "vapornet" is a "subnet of the Princeton network." (I don't know what that means)
I would not give this a second thought if it weren't the case that:
(1) I don't remember ever having seen a window like this from the Firewall before. Is this normal? Should Finder be going around looking to hook up like this, and why haven't I ever been asked this before?
(2) More importantly, for the last several months, I have not been able to open the actual Firewall to look at anything because everytime I do, the program hangs and does not respond (the rainbow swirly thing keeps spinning) unless I force quit (this is a problem that preceded the window pop up thing). I hadn't really cared about this all that much before, since I saw no reason to go into the Firewall interface, but now I'd like to check the history to see what I allowed. Is there some way to fix Firewall? Should I reinstall? How should I do that? And will doing so erase the previous history log?
