******************************************************************

Thank you for downloading the virus definition update for Norton
AntiVirus version 3.0.  This text file describes the contents of
the .ZIP file and installation procedure.

If your version of Norton AntiVirus 3.0 for Windows and DOS is dated 
before 6-23-94, you will need to update it using the NAV August Patch
in order to detect the SMEG (Pathogen and Queeg) and Natas viruses. If 
you have not updated your version, download the NAV August Patch from 
the Symantec BBS, CompuServe, or America Online. The file is called 
NAVUP.ZIP and is located where the monthly update files are normally 
found. Alternately, you may call Customer Service at (800)331-7234 to 
obtain the NAV August Patch disk. 


******************************************************************

All contents of this file have been scanned by Norton AntiVirus 
3.0 and are free from virus infection. The virus definition and 
repair data included with this update are for use by Norton 
AntiVirus 3.0 only. The virus definitions and repair data will

VIRSCAN.DAT     This data file is used by Norton AntiVirus 3.0 to
                detect and repair viruses. This file completely 
                replaces the existing virus definitions in your 
                Norton AntiVirus 3.0 directory.

VIRSCAN.INF     This data file is used by Norton AntiVirus 3.0 to 
                display virus information, such as virus
                characteristics and behavior. This file is not 
                required to detect or repair viruses. To view this
                information, use the Virus List command in the
                Tools menu.

                     Loading New Definitions

NOTE: The new virus definition files contained in this .ZIP file
      replace the corresponding Norton AntiVirus 3.0 files. Only 
      the most recent virus definitions are required to fully 
      update your copy of Norton AntiVirus 3.0.

******************************************************************

To update Norton AntiVirus 3.0 virus definitions:
    
    1. Copy VIRSCAN.DAT and VIRSCAN.INF into the Norton 
       AntiVirus 3.0 directory.
    
    2. Scan a drive, directory, or file with Norton AntiVirus 
       3.0, in either DOS or Windows.
    
       This will generate new interim files and update the
       automatic protection TSR.
    
    3. Reboot your computer to load the updated automatic
       protection TSR.

 TIP: If you unzipped this file inside your \NAV directory, 
      (\NDW for users of Norton Desktop for Windows), then 
      step 1 is already completed. If you unzipped this file
      in a different directory, copy the extracted files to 
      your \NAV directory.  If prompted to overwrite existing 
      files, select Yes.
