SYMANTEC CORPORATION - PETER NORTON GROUP
README10.TXT file for Norton AntiVirus Version 4.0
**********************************************************************
WELCOME TO NORTON ANTIVIRUS!
This file contains information about Norton AntiVirus.
To print this file from the DOS prompt, type: COPY README10.TXT PRN:
This document has two sections:
1) General Program Information
2) Compatibility Information
*******************************
* General Program Information *
*******************************
***** AUTOMATIC PROTECTION ONLINE *****
The Administrator's Guide has an incorrect entry for the [Win32]
section. The correct command is CMD= not CMDLINE=.
***** _DEFAULT.NNS CHANGE FROM PRIOR VERSIONS *****
1) The default options ScanOpen and ScanCreate in the [AutoProtect]
Section have been defaulted to the ON state. This helps facilitate the
detection of macro viruses.
2) ***** FORCING A REBOOT AFTER DISTRIBUTION *****
You may force a reboot of the user's system even if Windows is
actively running on the system by specifying "3" as the reboot option
in the [Install/Update] section:
; 0=Don't Reboot
; 1=Reboot unless in Windows
; 2=Prompt to Reboot
; 3=Reboot upon completion, even if in Windows
ActionAfterInstalling=3
3) ***** AUTOMATIC LIVEUPDATE SETTING *****
A new feature in Norton AntiVirus 4.0 is the program's ability to run
LiveUpdate on the workstation when the virus definitions are out of date.
To enable this feature, put the following entry in the [WIN.INI_NAV16]
section:
AutomaticLiveUpdate=1
4) ***** ADDING A NEW "LOAD=" or "RUN=" LINE INTO THE WIN.INI *****
A new feature in Norton AntiVirus 4.0 is the program's ability to
create a new (additional) load= or run= line when required. Simply add
an extra "+" sign to the directive line in the [WIN.INI_Windows]
section:
Traditional method:
+LOAD=%NAVDIR%NAVTSRW.EXE
New line method:
+LOAD=+%NAVDIR%NAVTSRW.EXE
5) ***** [Put NAVAfter] SECTION NAME CHANGED TO [PutNAVTSRAfter] *****
This takes care of a problem introduced with a previous release. This
allows the user to specify where to put the NAVTSR driver in the
Autoexec.bat file.
6) ***** COMMAND LINE SWITCHES CAN BE ADDED TO CLOAKING DRIVER *****
Switches for the cloaking driver (Cloaking.exe) can now be specified
with a new entry in the [Install/Update] section:
CloakingCmdLine=/presence /u
7) ***** COMMAND LINE ARGUMENTS CAN BE EASILY UPDATED NOW *****
A new entry in the [Install/Update] section allows the command line
argument changes for Navtsr.exe, Cloaking.exe and Nav.exe that are
installed in the Autoexec.bat and Config.sys files to be updated in
one pass. By setting the entry to "1", all three nav executables are
tested for compliance with the strings after AutoProtectCmdLine= or
CloakingCmdLine= or ScannerCmdLine= entries. If necessary, the
Autoexec.bat or Config.sys file(s) are brought up to date.
UpdateAllArguments=1
8) ***** CONTROL OVER BUTTONS IN GENERAL SECTION *****
Several icons on the main NAV display can be surpressed by adjusting entries
in the WIN.INI file.
VirusListActive=1
ScheduleActive=1
ALogActive=1
LiveUpdateActive=1
DefStateActive=1
9) ***** CONTROL OVER PERFORMANCE SECTION *****
This switch will enable the display of the section that sets OpenMode and
ExcludeFirst in the "General" property page of NAV.
EnablePerformanceSection=1
***** UNWANTED OR DUPICATE NAVTSR AND CLOAKING ENTRIES REMOVED *****
Duplicate entries of Navtsr.exe and Cloaking.exe are religiously
removed from the Config.sys file.
***** WIN.INI NOW SAVED CORRECTLY *****
The problem with the Win.ini file not being saved or not being saved
Correctly now works. The Undo.bat file will now restore all the saved
Files.
***** AUTOMATIC PROTECTION ONLINE *****
The Norton AntiVirus Automatic Protection TSR provides real-time
protection to prevent virus-infected files from being downloaded
from the Internet, bulletin boards, or other online sources. For
full protection while downloading, enable the Scan on Open and
Scan on Create options in the Options - Auto-Protect Settings dialog
box.
***** WORD AND EXCEL MACRO VIRUS DETECTION *****
New installations of Norton AntiVirus detect Word and Excel Macro
Viruses automatically. If you are upgrading from a previous version,
you must modify the Program Files Extensions List and add the .DOC and
.DOT extensions.
***** WARM BOOT TRAP *****
TSRs, device drivers, or programs that trap warm boots (Ctrl+Alt+Del)
may override Automatic Protection's ability to check for boot viruses
on floppy disks. Likewise, programs that perform a warm boot without
Ctrl+Alt+Del will bypass the automatic check for boot viruses.
***** INOCULATION FILES *****
The inoculation files are NAVSYS.DAT and NAVINOC.DAT. They are stored
in the NCDTREE directory by default.
***** "AUTOPROTECT SELF-TEST FAILED" ERROR *****
Although this error occurs in Windows, it is almost always caused by
insufficient free conventional memory. You need at least 475K of
conventional memory available before starting Windows. To check the
amount of conventional memory available, type "MEM /C" at a DOS prompt
before starting Windows. The value reported for "largest executable
program size" must be greater than 475K.
***** FILES STATEMENT IN CONFIG.SYS *****
Norton AntiVirus requires that FILES be set to at least 25 in your
CONFIG.SYS file. During install, NAV makes sure the FILES statement
in CONFIG.SYS is adequate for your hard disk boot. If you boot from
a floppy disk without this setting, Norton AntiVirus will fail to run
and display the following message: "The file NAV.EXE has been
altered."
To boot from a floppy disk and be able to run Norton AntiVirus, make
sure the floppy disk contains a CONFIG.SYS file with at least a
"FILES=25" statement.
***** SCANNING ZIP ARCHIVES *****
The following limitations exist when scanning ZIP archives:
* Password protected files in a ZIP archive (stored with the
PKZIP -s option) are not scanned.
* Norton AntiVirus for DOS cannot scan ZIP archives with more than
about 1,000 files; the exact number of files depends on the
amount of available memory.
***** AUTOMATIC PROTECTION AND MEMORY OPTIMIZATION *****
The automatic protection TSR does not require memory optimization to
Use UMBs efficiently. If you are planning to optimize memory, we
Recommend doing so before installing Norton AntiVirus. If Norton
AntiVirus is already installed, remove automatic protection from
CONFIG.SYS or AUTOEXEC.BAT and reboot before running the optimization
program. Once the memory optimization is complete, add the command to
load automatic protection back to the appropriate file and reboot.
***** SCANNING IN BATCH MODE / UNATTENDED SCANNING *****
If you want to run Norton AntiVirus unattended so that it doesn't
pause when alert boxes appear, use the following procedure:
To customize Norton AntiVirus to run in batch mode:
1) Select one of the following options from the "When a Virus is Found"
drop-down list box in the Options - Scanner Settings dialog box:
"Notify Only," "Repair Automatically," or "Delete Automatically."
2) Check the "Immediate Notify" check box in the Scanner Advanced
Settings dialog box.
3) Check the "Remove Alert Dialog After" check box in the Options -
Alerts Settings dialog box, then enter 1 in the "Seconds" text
box.
***** TECHNOTE.TXT *****
This text file contains information about viruses that
cause unique problems and require special handling.
***** RUNNING THE DOS SCANNER WHEN BOOTING WITHOUT STARTUP FILES *****
The DOS scanner on certain 386 and early 486 machines may have problems
running when you boot up without a CONFIG.SYS or AUTOEXEC.BAT file. You
can eliminate these problems by booting up with DEVICE=HIMEM.SYS in the
CONFIG.SYS or by typing in "SET DOS16M=0" (without the quotes) at the DOS
prompt prior to running the DOS scanner.
*****************************
* Compatibility Information *
*****************************
***** MICROSOFT WINDOWS *****
If you are prompted to inoculate a file while windows is loading and
your computer subsequently "hangs," type the following command at
the DOS prompt to inoculate the windows files:
C:\NAV\NAV /REFRESH C:\WINDOWS /S
If Norton AntiVirus is not installed in C:\NAV or Windows is not
installed in C:\WINDOWS, substitute the appropriate path.
After inoculating the windows files you can then load Windows.
***** WINDOWS SCREEN SAVER AND SCHEDULER *****
If your screen saver is not activating with Scheduler loaded,
select "Hide When Iconized" from the Scheduler Options menu. If
you don't want to hide the Scheduler icon, add the following
statement to the [Scheduler] section in the SCHEDULE.INI
file:
ICONTIME=0
The SCHEDULE.INI file is located in your Windows directory.
***** AUTOMATIC PROTECTION AND UPDATING SOFTWARE *****
If you have configured Norton AntiVirus to detect unknown viruses using the
Virus Sensor Technology feature, you may get unknown virus alerts when
installing or updating software. This does not necessarily mean the file is
infected with an unknown virus. The installation process may be overwriting
existing files or expanding compressed files, which may trigger an alert.
***** AUTOMATIC PROTECTION AND COMPRESSED DRIVES *****
If you install Norton AntiVirus on a compressed drive and subsequently get
the error message "NAVOPTS.DAT file not found, default settings loaded,"
install automatic protection as a TSR.
***** BYPASS KEYS WITH MEMORY MANAGERS *****
By default, pressing both ALT keys will bypass the loading of the Auto-Protect
feature of Norton AntiVirus. The memory managers, QEMM and 386MAX, also use
both ALT keys to bypass their loading. If you are using either of these
memory managers, you may wish to modify the bypass keys used by Norton
AntiVirus.
***** NORTON ADMINISTRATOR FOR NETWORKS *****
If you are using the License Metering feature of Norton Administrator for
Networks, turn off the "Use UNC Path Names" option in the License Metering
Configuration screen. This ensures maximum compatibility with Norton
AntiVirus.
***** INSTALLING FROM AN OS/2 DOS BOX *****
Norton AntiVirus will not install properly from within an OS/2 DOS box.
To properly install in an OS/2 DOS box, run "INSTALL /NOMTC" for
"No Multitasking Check". This will bypass the Norton AntiVirus attempt
to check for a multitasking environment.
***** INSTALLING WITH AFTER DARK VERSION 3 *****
If you experience problems with the Windows TSR in conjunction with the
After Dark 3 screen saver, you may turn off the startup memory scanning
in the Windows TSR to avoid any problems. You may scan memory prior to
starting Windows with the DOS TSR and the use of the alternative options
switch (/OPTS). Please see your documentation for more details on the use
of this command line parameter.
***** PERFORMANCE ISSUES UNDER NOVELL CLIENT32 ON A NETWORK *****
If you are experiencing extreme performance degredation while using the
Windows TSR over a network while using Novell's Client32 software make
the following change to your WIN.INI file:
[NAV16]
OpenShared=0
***** NETX LOADING HIGH *****
Under certain circumstances, if the NETX network driver is loaded high
after the TSR is loaded, the network alerting in the DOS TSR may not work
correctly. If you experience this problem, you can type in NAVTSR /NR+
to reinstate the alerting.
***** QUARTERDECK'S QUICKBOOT FEATURE *****
Please note that Quickboot bypasses the system memory scanning and this
causes the warm boot floppy scanning to be skipped.
***** BREAKING OUT OF A NETWORK DISTRIBUTION *****
Please be aware that users can break out of a network distribution while
we are in the process of scanning for viruses on their system prior to
installation. You may turn off the scanning in order to prevent the users
from breaking out of the installation process.
