A "new and improved" version. It infects .EXE files as well as .COM files,
and is somewhat variable. Some attempts were made to make it difficult to
disassemble or modify the virus, but this "protection" is easily defeated.
The virus contains one unusual feature, it infects COMMAND.COM by
overwriting it, in the same manner as the Lehigh virus does, so no change
in length is visible. Unlike Virus-90, this virus was not made available
to the public.
