This virus was first reported in the German AGIPLAN company, but then it
disappeared for nearly two years, until a sample appeared in South
Africa. This re-appearance is rather mysterious, as this sample was not
a "natural" infection by the virus.
Structurally the virus is similar to the Zero Bug virus, as both add 1536
bytes to the beginning of the programs they infect. The virus will not
have any serious effects until it has been active on an infected machine
for several months, but then it will start corrupting write operations.
