Hilmar,
A bit of a correction here, although "viri" & spelling variations are becoming popular as the plural (I haven't found a major anti-virus company using it yet though), it is not correct Latin :

"viri" is the plural form of "vir" meaning "man" - in Latin "virus" was a word a bit like sheep - it was used unchanged in singular & plural form. These types of words from latin tend to use "-es" to denote the plural, so "viruses" is the correct plural form of "virus".
