%%Notes: Infects .COM files. All characters "0" (zero) will be exchanged 
with other characters. Exchange characters are 01h, 2Ah, 5Fh, 3Ch, 5Eh, 
3Eh and 30h, in which case the attribute is set to back- ground color 
(i.e. the character is invisible). This routine uses about 10% of CPU-
time (system is slowed down accordingly).

The Dark Avenger may be a descendant of this virus.     Typical text in 
Virus body (readable with HexDump-utilities): "ZE","COMSPEC=C:", 
"C:\COMMAND.COM". 
In infected .COM files the "seconds" field of the timestamp is changed 
to 62 sec (similar to GhostBalls original Vienna viruses).
