There was a boot-sector
virus on the Atari ST
called Cookie Monster
. Once in memory, as well as the usual smearing itself across every disk put in the drive, it would appear at n/2^(Number of times popped up) intervals (I think n was about 5 minutes), and say 'I want a cookie
'. When the user typed 'cookie
', it went away.
Doing the math
, after about 4 or 5 popups the machine was effectively unusable.
You know an emulator is good when you see an emulated virus spreading through your emulated disk images...
