Introduction
============

NeVirus can detect (and prevent) attempts to modify executable files
such as: Obey, Utility, BASIC and much more.


Overview
========

Most of the viruses open an executable for READ/WRITE which is *not*
a usual action. The executable creators (assemblers, editors, compilers)
if they open the file it will be for WRITE only.

There are viruses which load a file in memory, modify it and save
it back replacing the original executable. NeVirus detects those as
well.

Some installers, patchers and registration applications/utilities may
modify executables just like viruses; that is *not* something the happens
everyday.

NeVirus will ask you what to do when someone will attempt to modify an
executable.


Technical details
=================

Detecting visuses
-----------------
Special care has been taken in order to detect *only* viruses,
if you face a case where NeVirus will /think/ it found a virus
but you *know* it isn't I would like to hear from you.

Which viruses will *not* be detected
------------------------------------
Viruses that:
  - know about NeVirus and they found a way to fool it,
    it is easy but *not* as easy as "*rmkill nevirus".

NeVirus is written while explaining to an old PC programmer-friend of mine
how (most of) the viruses infect executable files.
