Obligatory nitpick regarding the plural of "virus": http://linuxmafia.com/~rick/faq/plural-of-virus.html

Richard Karsmakers used "virii" to describe a plural of computer virus in the 16-bit era, largely on the basis that it was shorter. It isn't correct Latin, but it is a VX scene thing, so is absolutely correct in this context.
