No, it is not hard to argue with that. He is selling something. It is indeed possible to write viruses for *nix systems, but when people like him talk about exploits, they neglect to say that it only works if you have physical access to the machine or know the root password - in which case the OS is not the problem. I am well aware of the value of the "never say never" meme, but Cluley is just another one of the Windows apologists / salesmen.
