Saw someone on IRC misspel the plural for virus again. I don't want to reproduce it here because I don't want another hit for it in google, but it basically ended with an i ;) So I went out and found some proof of it being viruses and came to this. I like the summary: "Learn how to spell unless you are participating in an undercover operation to apprehend clueless script kiddies!". Someone else quickly found this link, which explains the latin background a little more.
