    I found a few Win2K machines with this beastie installed on them.  It's
    BO2K with a custom builtin plugin.  If you've got the same one as I did,
    wlogin.exe is acting as an IRC client, connected to an IRC server (typically
    irc.icq.com) and sitting on a channel, waiting for commands.
    
    The typical usage of this thing is to DDOS people.
