                           Loading New Definitions

Note: The files contained on this disk completely replace the corresponding 
      files contained within Norton AntiVirus products. Only the most recent 
      virus definitions are required to fully update Norton AntiVirus
      products. 

      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.

      Important note for Norton AntiVirus for NetWare 1.0 users.

      If your Norton AntiVirus for Netware 1.0 is dated before 7-13-94 
      you will need to update your version. Using an older version of the 
      NLM with these virus definitions may cause false alarms with garbled 
      virus names. For information on how to receive the update, please 
      call Customer Service at (800)441-7234.

To update Norton AntiVirus 3.0 virus definitions from the DOS prompt:

1) Insert the Virus Definitions disk into the floppy drive.

2) Type the following at the DOS prompt:

   COPY A:\NAV30\VIR*.* C:\NAV

   where "C:\NAV" is the drive and directory where Norton 
   AntiVirus is installed.

   Note that this will also copy a new VIRLIST2.DLL to support this, and 
   future, Virus Definition updates.

3) Launch Norton AntiVirus, then scan your drives.

   Each update contains detection for newly discovered viruses.
   Performing a virus scan will also force Norton AntiVirus to 
   recognize that a new VIRSCAN.DAT file is in place.

4) Reboot your computer so that the Automatic Protection TSR
   uses the newest virus definitions.

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

To update the Norton AntiVirus Network Manager (NAVUPDAT) virus definitions:

   Note: The Norton AntiVirus Network Manager maintains a network 
         copy of Norton AntiVirus to support distribution. Make sure 
         you have access rights that allow read and write operations 
         to the NAVUPDAT directory.

1) Insert the Virus Definitions disk into the floppy drive.

2) Type the following at the DOS prompt:

   COPY A:\NAV30\NAVUPDAT\INSC*.* F:\ADMIN\NAVUPDAT
   COPY A:\NAV30\VIR*.* F:\ADMIN\NAVUPDAT

   where "F:\ADMIN\NAVUPDAT" is the network directory where the 
   Norton AntiVirus Network Manager files reside.

   Note that this will also copy a new VIRLIST2.DLL to support this, and 
   future, Virus Definition updates.

The new definition files are now in place for network distribution.

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

To update Norton AntiVirus for NetWare 1.0 virus definitions:

1) Map a drive letter to the volume and directory where Norton 
   AntiVirus for NetWare is installed.

2) Insert the Virus Definitions disk into the floppy drive.

3) Disable Norton AntiVirus for NetWare, using either the Norton
   AntiVirus for NetWare Windows configuration component, or at the 
   server console using the function keys.

4) Type the following at the DOS prompt:

   COPY A:\NAV30\VIRS*.* H:
   COPY A:\NAVNLM\VIRS*.* H:

   where H: is mapped to the volume/directory where Norton AntiVirus
   for NetWare is installed.

5) To copy the new VIRLIST2.DLL that supports this, and future, Virus 
   Definition updates, type the following at the DOS prompt:

   COPY A:\NAV30\VIRLIST2.DLL H:

   where H: is mapped to the volume/directory where Norton AntiVirus
   for NetWare configuration component is installed.

6) Enable Norton AntiVirus for NetWare, using either the Norton
   AntiVirus for NetWare Windows configuration component, or at the 
   server console using the function keys.
