This virus is not a well written one. In fact it is so badly written that in many cases it will simply cause the system to "hang", instead of properly infecting it. It is not a serious threat. The virus will only work on machines with at least 640K of memory, because it always tries to hide itself at the same address, starting at 9000:0000. The original infected program distributed by the author contained the string:
(c)Stupid 1989 Virushmock!
