Ken,

my personal copy of "Friday, 13th" virus (alias "Israel#1", alias "PLO")
exhibits a characteristic "black hole" in the lower left half of EGA
screens:  If you set the background color to blue, say, you'll see a
black rectangle, sized 1 by 8 (approximately) character-boxes.  This
feature could well cause somebody to dub this virus "Little Black Box".

Hence, I suppose, you just hit on a new alias for the notorious
"Friday, 13th".

Best wishes
             Otto

[Ed. Bingo.  Little Black Box is an alias for Black Hole...]
