The message
from Kay Easton contains these words:
OED "virus pl viruses"
Yes - anglicised, and in the context of virus the living organism and by
association, virus the destructive self-replicating computer program.
However, the OED is not an authority to consult on matters of Latin
grammar. (Nor, as certain Urglers have pointed out, on botanic
accuracy.)
