Gosh ukbob your like a fundamentalist defending their religion. The right to privacy doesnt mean the right to totally wreck other ppls computers. When you purposely infect others you are defeating the whole purpose of shared networks. The alcra worm turns up when you search for just about anything and causes so much damage. the number of sources holding it remains constant so these pple are doing it on purpose. Maybe administrators could run a programme randomly that stops these known worms. like when they randomly assign turbo charged to ppl, it could search for and stop the trojans.
