This virus was written by two brothers in Switzerland, 18 and 21 years
old. The virus is related to the 'Flip' virus - possibly they wrote it as
well. Tequila is difficult to detect as is uses a variable encryption
algorithm. When an infected program is run, the virus will infect the MBR
of the hard disk, so the next time the computer is booted, the virus will
be active in memory, ready to infect .EXE files as they are run. One
interesting effect of the virus is the display of a crude, character-based
Mandelbrot set image on the screen.
