Not memory resident, this virus is non-removable because it overwrites 
part of the infected file with itself, making recovery impossible.  
Mostly infects EXE files, although .COM files can be infected, the 
infection mechanism treats .COM files as .EXE files.
NMAN B writes out a message, where NMAN does not.  NMAN B also is 
nastier to the hard disk, and can erase the disk, but it is not certain 
if the erasure is intentional or not.

It appears that this virus was written with the Borland Turbo C++ 
compiler, that's why this virus is sometimes called "C virus".

Virus sample examined had a date of 9/24/91, so virus is at least that 
old.
