With access-lists you can compare them to RADIUS for dial-up users and see
who they are and call them. Think before you speak.

If an ISPs customer is causing traffic and infecting otehr customers what
would you expect the ISP to do? Take a long lunch break and ignore the
problem?

And who are you to claim infecting unknowing people wit hanotehr virus is
any way to solve teh problem. I mean someone brought up an interestng
point about CodeGreen, does it actually stop once a machien is fixed or
just keep infecting other machines?

My approach works, I have been using for a month in a corporate network
and the for the dial-up users on the road. They call in, they are
informed of the problem, they are sent the fixes, they install them, all
done.

LESS PRONE TO ERROR? HELLO? First of all CodeGreen does seek out victims
via scanning, second with human interaction if there are problems they can
be worked out in real time. What if CodeGreen doesn't patch a system say
in eh Ukraine? And what if that system fails as a result of the so-called
"good" worm, what? What if that machien going down costs a company
thousands of dollars and they are stuck trying to figure out why their
system failed? How is that cost effective? The only cost effective
approach there is if they sue the party that unleashed the worm on their
system that caused the failure. If something goes wrong, nobody has been
informed of what was being done to the system, it could takes hours or
days oftime and manpower to fix whatever damage might have been done.
