| Excuse me. The plural of virus is NOT viri, and certainly not virii.
viri is the plural... of virus, that is, man.
virii assumes the existance of 'virius', which is just ridiculous.
As far as virus, viri (= slime, poison) goes, it has no plural. Being a mass noun and also a rare second declension neuter ending in -us, there is no record of the use of _anything_ as the plural of viri in the Latin.
Now, in English, the plural of virus is viruses. The OED places it as such; so do Birchfield's /Modern English Usage/ and the /Cambridge Encyclopedia of the English Language/.
