Cheese: If it's good (worm), let it be!
The Cheese worm appears to be different. Dubbed the Cheese worm, the program is basically a self-spreading patch. It enters servers that have already been compromised by a previous bit of malicious code--the 3-month-old 1i0n worm--and closes the back door behind it, adding security to the system.
Taken individually, the Cheese Worm is not a good thing. The last thing we need is another invasion by some nameless hacker using up our network resources.
