In a theoretical sense, I agree, but in a practical one, for whatever reason, mac users have not had to worry about running anti-virus software. This is great, as anti-virus for windows, in my limited experience, seems to suck down vast system resources and generally be a necessary pain. The distinction OP is trying to make is an important one for the implications that the different terms carry. For worms, to protect yourself, you just have to avoid doing the computer equivalent of picking up a needle off the sidewalk and jabbing it into your arm. not hard. For viruses, I have to avoid breathing. The original topic says that snow leopard has anti-virus software, which means apple is admitting that everyone without snow leopard is boned. But, if the fact is that it's just anti-worm software, well, thanks apple for the chain mail sleeves, but I probably would have been OK otherwise.
