Wikipedia has an interesting article about the plural of virus.
In the English language, the standard plural of virus is viruses. This
is the most frequently occurring form of the plural, and refers to
both a biological virus and a computer virus.
The less frequent variations viri and virii are virtually unknown in
edited prose, and no major dictionary recognizes them as alternative
forms. Their occurrence can be variously attributed to hypercorrection
formed by analogy to Latin plurals such as radii; idiosyncratic use as
jargon among a group, such as computer hackers; and deliberate word
play, such as on BBSs (see, e.g.: leet).
To complicate matters further, viri is already used in Latin as the
plural of vir, meaning "man" (thus making viri mean "men")
