-
- ***** NORTON ANTIVIRUS STARTUP FILE ENTRIES *****
- This section lists the entries Norton AntiVirus adds to AUTOEXEC.BAT, CONFIG.SYS, WIN.INI, and SYSTEM.INI by default.
-
- The following is added to AUTOEXEC.BAT:
-
- PATH C:\NAV;%PATH%
-
- The following is added to CONFIG.SYS:
-
- DEVICE=C:\NAV\CLOAKING.EXE
- DEVICE=C:\NAV\NAVTSR.EXE
-
- The following is added to WIN.INI:
-
- [windows]
- load=c:\nav\navtsrw.exe
-
- [NAV16]
- BypassRepairWizard=0
- RepairWizardDefault=1
- AutomaticLiveUpdate=0
-
- The following is added to SYSTEM.INI:
-
- device=symevnt.386
-
- ***** INSTALLING ON COMPUTERS WITH MENUING SYSTEMS OR MULTI-BOOT CONFIGURATIONS *****
- By default, Norton AntiVirus adds the following line to AUTOEXEC.BAT:
-
- PATH C:\NAV;%PATH%
-
- Norton AntiVirus also adds the following lines to CONFIG.SYS:
-
- DEVICE=C:\NAV\CLOAKING.EXE
- DEVICE=C:\NAV\NAVTSR.EXE
-
- If, when you start up your computer, it displays a menuing system or a menu
- from which you can select from more than one operating system, in most
- cases Norton AntiVirus adds the above lines as the last in your startup
- files. If Norton AntiVirus doesn't load, move the location of these lines
- earlier in the AUTOEXEC.BAT and CONFIG.SYS files.
-
- ***** 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.
-
- ***** "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.
-
- ***** EXCLUSIONS *****
- Norton AntiVirus scans for files with .XL?, .DOC, and .DOT extensions.
- However, these extensions are excluded from unknown virus scanning and
- inoculation detection because they are subject to frequent changes.
-
- ***** 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.
-
- NOTE: For more information on these options, see "Customizing Virus
- Checking" in the User's Guide. For information on using command-line
- switches, see the "Using Command-Line Switches" appendix in the User's
- Guide.
-
- ***** TECHNOTE.TXT *****
- This text file contains information about viruses that cause unique
- problems and require special handling.
-
- ***** REMOVING NORTON ANTIVIRUS AS A NETSCAPE HELPER APPLICATION *****
- To remove Norton AntiVirus as a Netscape helper application, run Netscape
- and select Options and then General Preferences from the menu bar. Click
- on the Helpers tab. For each File Type where NAVW is the Action, either
- click the Browse button to select another application to be the helper
- application or select the radial button "Unknown: Prompt User" to be
- prompted for an action when downloading a file of this type.
-
- ***** 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
-
- ***** RESTORING WITH DOS RESCUE *****
- When you restore with the DOS Rescue program, it may warn you that the
- info probably wasn't saved on this computer. This is due to a memory
- manager being present at the time you created the disks. You may
- ignore this warning.
-
- ***** INCREASING PERFORMANCE WITH ADDITONAL SYSTEM RAM *****
- The minimum RAM requirement for Norton AntiVirus version 4.0 is 4
- megabytes. We recommend that you have at least 8 megabytes for faster,
- smoother performance.
-
- ***** INSTALLING NORTON ANTIVIRUS 4.0 TO AN EXISTING 3.0 INSTALLATION *****
- We recommend installing Norton AntiVirus to the same directory as your 3.0
- installation. This will facilitate the reuse of your existing startup file
- directives.
-
- **************************************************************************
- 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. For instructions, see "Using
- Automatic Protection as a TSR" in the User's Guide.
-
- ***** 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. For instructions, see your User's Guide.
-
- ***** ACT! FOR WINDOWS 3.X *****
- If you are using ACT! for Windows 3.x that includes WIN32s, you will need
- to add the following entry to WIN.INI:
- [NAV16]
- ExcludeFirst=1
-
- ***** CLOAKING DRIVERS *****
- Norton AntiVirus does not check for additional cloaking drivers.
-
- ***** 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.
-
- ***** 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.
-
- ***** SYSTEMS WITH DISK MANAGER SOFTWARE *****
- On a system that needs disk manager software to access large hard drives,
- you must use a bootable disk made with the disk manager software before
- running the RESCUE.EXE program. If you need to run the RESCUE.EXE program
- to restore your hard drive, first boot from the disk made with the disk
- manager software, then put in the Norton Rescue Boot disk made from the
- DOS or Windows Rescue program and run RESCUE.EXE. Do not boot directory
- to the Norton Rescue Boot Disk in this case to restore your system or you
- could cause damage to your system files.
-
- ***** 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 network 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.
