		   Loading New Definitions

Note:  The files contained in this zip file, referred to as a virus
       definition update set, completely replace the corresponding
       files contained within the product.  Only the latest virus
       definition set is required to update the product.

******************************************************************
NAV 3.0 has greatly simplified the definition update process.  
There are now only two steps to updating your copy of Norton 
AntiVirus.

	1. Copy VIRSCAN.DAT and VIRSCAN.INF into the Norton
           AntiVirus directory.
	
	2. Scan with NAV, in either DOS or Windows.
	
NOTES:

If you have unzipped this file inside your \NAV directory, (\NDW 
for users of Norton Desktop for Windows), then you have already 
completed the first step.  If you unzipped the three files into 
another directory, or are viewing this, still ZIPped (by using 
a ZIP management program) then copy the extracted files to your 
NAV directory.  You want to overwrite the existing, old, data 
files, in case you are asked.

Then, in either DOS or Windows, activate NAV and scan any 
drive, directory or file.  This will generate new interim 
files, and update NAVTSR.

Exiting NAV (and Windows) and rebooting your computer to load 
the new NAVTSR completes the process.  You are now operating 
with the latest anti-virus protection.
