| Release Notes                   
| Version 1.2 - 15 November 1993
-----------------------------------

Both DOS and Windows versions now scan memory for viruses before performing
a checksum scan.  Secure and heuristic scans already search memory for
viruses before running.  If memory is found to be free of viruses, it
will not be searched on subsequent disk scans.

-----------------------------------
| Release Notes                   
| Version 1.1 - 11 October 1993
-----------------------------------

An icon toolbar has been added to the Windows version, allowing one click
access to all major scanner features.  The on-line help system has been
updated to reflect this change.
-----
Changed DOS version to 1.1 to reflect minor changes and to keep the
same version number between DOS and Windows.

-----------------------------------

Rescue Disk
-----------

The full Rescue Disk feature is implemented only in the DOS version
of VirusNet/Pro.  The Windows version allows you to view and delete
workstation rescue information but it does not allow you to create
or restore this information.

= Scanning Engine Release Notes                                      =
======================================================================

Version 2.10 - Released 11 November 1993

   Checksums have been added to positively identify viruses and their
   variants.  This produces a substantial increase in the accuracy of
   virus identification and removal.

Version 2.09f - Released 11 October 1993

   When running under OS/2 2.1, version 2.09 and earlier did not recognize
   HPFS file systems, and just reported "Error reading C:", unless boot
   sector scanning was disabled, which unfortunately meant that the
   MBR was not scanned either.

   2.09 was unable to disinfect certain boot sector viruses, such as
   Stoned.NoInt from hard disks, and would simply report "Original MBR
   not found".

   False "Ultimatum" positives were fixed.

Version 2.09f - minor improvements and changes:

   The /TROJAN and /NOTROJAN switches have been eliminated, as searching
   for Trojans does not require any significant extra processing, as it
   used to.  VirusNet will now always search for the Trojans it recognizes
   and report them if found.

   VirusNet now reports which program have been modified by adding the
   Central Point/Turbo Anti-Virus self-check code.  We do not recommend
   adding external integrity checking code to programs, as many programs
   perform their own interlnal self-intecrity check, and will consider the
   added code a virus infection.

Version 2.09 - Released 20 July 1993

	VirusNet will now always scan the MBR(s) even if no logical
	partitions are found on the hard disk(s).

	The behaviour of the /NOFILE switch has been changed - it now
	implies /NOUSER (in files), /NOPACKED and /NOTROJAN as well.

	A new exit code (7) was added: Insufficient memory.  Previously
	VirusNet would return 1 (general error) in this case.

	VirusNet now normally scans the memory area between 640K and 1M,
	as certain viruses such as Tremor can hide there.  To disable this
	(and only scan 640K) a new command-line switch "/640" is provided.

	A new command-line switch "/MONO" was added.  It gives monochrome
	operation on color displays, which is useful on certain laptops.

VirusNet v2.08a - Released 6 May 1993

Maintenance release.
Corrected problem with VIRSTOP /DISK option when run from network drives.
Enhanced boot sector virus removal.

VirusNet v2.08 - Released 6 April 1993

Added two new utilities:

DO-ONCE allows the scanner to be run during bootup or network login
at set intervals.

VNDEPLOY (included with VirusNet LAN Extended and site licenses) automatically
installs and updates workstation virus protection.

***** DO-ONCE *****

Version 2.3 - Released 28 February 1993

The DO-ONCE utility program has been added which allows the scanner to
be run from the AUTOEXEC.BAT file once per day, week or month. DO-ONCE
creates a DO-ONCE.DAT file in the root directory of the current drive.
This file contains the encoded date of the last time the scanner was run,
and prevents automatic scans from activating prematurely.

Syntax:  DO-ONCE [/q] [@DAY] [d:\path\] FILENAME.EXT [param1 param2 ...]

/q         = Sets quiet mode (less clutter on screen)

@DAY       = Optional parameter.  Executes only on that day.
	     NOTE:  @+ may be used to mean "on or after the specified day."
	     DAY may be MON, TUE, etc. (weekly)  or 12, 31, etc. (monthly)

d:\path\   = Optional parameter.  You can declare the path to
	     the program to be executed

FILENAME   = The program to be executed.  The EXTension is optional

param1...  = Any parameters to be passed to FILENAME (just as if
	     you typed them on the command line yourself)

Redirection:   `]  =  >       `[  =  <     `^  =  |

Examples:  We will assume that VirusNet is installed to C:\VN.  If your
	   install location is different, substitute the drive and
	   directory name where VirusNet is installed.

     To run the scanner once per day when you boot your computer,
     add the following line to your AUTOEXEC.BAT file:

	     C:\VNET\DO-ONCE /q C:\VN\VN /HARD

     To run the scanner every Monday or nearest day thereafter, and
     automatically disinfect any infected programs, add the following
     line to AUTOEXEC.BAT:

	     C:\VNET\DO-ONCE /q @MON+ C:\VN\VN /HARD /AUTO /DISINF

     To run the scanner once per month on the first day or nearest day
     thereafter, add the following line to AUTOEXEC.BAT:

	     C:\VNET\DO-ONCE /q @1+ C:\VN\VN /HARD

     To run the scanner every Monday and Friday, add two lines to your
     AUTOEXEC.BAT file:

	     C:\VNET\DO-ONCE /q @MON+ C:\VN\VN /HARD /AUTO /DISINF
	     C:\VNET\DO-ONCE /q @FRI+ C:\VN\VN /HARD /AUTO /DISINF

SPECIAL NETWORK NOTE - For users of our VirusNet LAN

DO-ONCE writes its data file in the root directory of the current drive.
To scan a workstation's local drives during network login, the current
drive must be set to C: when DO-ONCE is run.  If it is set to a network
drive, for example F:, each workstation's DO-ONCE.DAT file will overwrite
the previous workstation's DO-ONCE.DAT file.  The following example, which
assumes that VirusNet LAN is installed to F:\VN, shows the correct way to
automatically scan each workstation's local drives during network login:

	     <previous login script commands>
	     C:
	     F:\VN\DO-ONCE /q F:\VN\VN /HARD /AUTO /DISINF
	     <additional login script commands>

If your network allows a drive letter to be mapped to the user's HOME
directory, and users only log into their own workstation, then the
DO-ONCE.DAT file can be written to a network drive.  Instead of switching
to the C: drive before running DO-ONCE, map a network drive letter to the
user's HOME directory, switch to this drive, and run DO-ONCE.

Safetynet would like to extend a special thanks to Glen Snow for
developing the DO-ONCE program.

***** VNDEPLOY *****

Version 1.0 - Released 27 April 1993

Managing VirusNet on the workstation just got much easier with VNDEPLOY.
This utility is run from the network login script, and will automatically
install or update VirusNet files on the workstation hard disk.  VNDEPLOY
checks the dates of the files to determine if an update is needed.  It also
sets the workstation files to Read Only after the files are updated.

Automatic VirusNet workstation deployment and updates
-----------------------------------------------------

1. Copy VNDEPLOY.EXE to a directory in your network path.
2. Copy the VirusNet files to a directory on the file server (F:\VN for this
   example.)
3. Add the following line to the network login script:

	    VNDEPLOY F:\VN C:\VN

4. As new workstations log into the network, the C:\VN directory will be
   made on the workstation hard drive.  VirusNet files will then be copied
   to the C:\VN directory from F:\VN.

To update VirusNet workstation files, copy the updated VirusNet files to the
F:\VN directory.  Any new or more recent files will be automatically copied
to the workstation hard disk based on the file dates.  If no update is
necessary, no files will not be copied.

Automatic VirusNet interserver deployment and updates
-----------------------------------------------------

VNDEPLOY can also be used to install/update files from one network to
another, as long as the destination path is located on another file server.
Using this method, workstations connected to all file servers can be
automatically installed/updated by copying the VirusNet files to the main
file server.  The following example is for Netware networks, but other
networks will follow the same basic method.  Add the following lines to the
default file server login script:

	IF "%LOGIN_NAME"="SUPERVISOR" THEN BEGIN
	    #ATTACH SERVER2/SUPERVISOR
	    #MAP G:=SERVER2/SYS:
	    #VNDEPLOY F:\VN G:\VN
	END
	#VNDEPLOY F:\VN C:\VN

The first section is run only when SUPERVISOR logs into the server.  First,
SERVER2 is ATTACHED as SUPERVISOR and drive G: is mapped to the SERVER2 SYS:
volume.  Then VNDEPLOY is run to update the SERVER2 VirusNet directory with
the latest version stored on the current file server.  The next line, which
is run by each workstation, checks the workstation's copy of VirusNet and
updates it if necessary.

On all other servers, for example SERVER2, add the following lines to the
login script:

	#MAP G:=SYS:
	#VNDEPLOY G:\VN C:\VN

This will automatically install/update the workstation files on that file
server.
