In passing, what the heck are "virii"? Is this computerspeak? The plural of virus is viruses. If someone is trying to create a learned Latin plural, it would have to be viri, but that is the plural of vir meaning man. Virii would be the plural of virius, which as far as I know doesn't exist. Can't we stick to what Matt has called "common parlance"?-I think Matt started it, and I repeated it so as not to offend. I'd never seen the usage before.
