LOL that's so fanny.
I just read about it in irc-junkie.org:
Norton Internet Security DoS Vulnerability - Fri Feb 24, 2006 9:06 am
"I'm not quite sure what the problem is with this, but I'm told its a problem with norton personal firewall", this URL starts which have been going around IRC as a running fire.
Users who make use of the Norton Internet Security package will be disconnected from their IRC server when they receive any message, be it channel, private, notice when they contain the words startkeylogger or stopkeylogger.
These two commands are part of the list of commands for Spybot for which Norton released new code which introduced this bug.
Some users are going around populated channels now pasting the two commands. Some networks, like EFnet are acting against such users with kills, as we can see from the publicly available list of last executed kills and their reasons.
I always claimed that Norton Personal Firewall is a total crap.
