I am working on an article on "stealth" viruses, and was wondering if I had
missed any of them - here is my list:

Boot sector stealth viruses: Azusa, Brain, EDV, Evil Empire, Joshi and
	Spanish Telecom (boot)

Program stealth viruses: Fish6, Frodo, INT13, Number of the Beast, Whale
	ZeroHunt (Minnow)

Note that I do not consider any of the following program viruses to
belong to the "stealth" category, as they only fulfill one of the two
necessary conditions (hiding increase in length), but make no attempt
to hide the virus code, when an infected file is read.

3445, Diamond, Dir, Eddie-2000, Eddie-2100, Eddie-2, MG, PcVrsDs,
Spanish Telecom (file), SVC 4.0 and Zero Bug.

Did I overlook something ?
