I'm just objecting to the attitude that "since there's lots of computers
that have problems not caught by AV, we should totally ignore any discussion
of the ones that *are* easily detectable".

If there's 3M agobot boxes (probably a low estimate) and 9M "undetected" malware
boxes, that still means that we can find and fix 25% of the problem...

If you can't get the techies and managers to the point where they can usefully
deal with the script kiddie bots, there's no hope of dealing with more stealthy
stuff.

Also, you have to remember that the script kiddie bots are, if anything, *more*
dangerous than the stealthy stuff, precisely because they're run by script
kiddies. Compare the number of people killed by professional assassins and the
number of people killed by hot-headed gang members, and ponder for a bit....

Actually, my tcpdump uses 'socket(PF_NETLINK, SOCK_RAW, 0)', and my /bin/ps
pokes around in /proc.  There's no Windows API here. ;)

(And yes, I know how to use a loadable kernel module to cloak stuff on this
system, and how to do it if there's no kernel module support, and yes, there's
stuff in place to make it more difficult for one of those critters to get
itself installed...)
