Email message headers contain "X-NAV-TimeoutProtection"
-------------------------------------------------------
Norton AntiVirus (NAV) Email Protection options include a feature
called Timeout Protection.
This provides protection for your email client software during email
transfers. If your POP3 email server sends a message with an attachment
to the NAV POP3 email scanner without Timeout Protection enabled, there
is a possibility you could lose the message. Timeout Protection sends
"X-NAV-TimeoutProtection?:X" as a continuous header to the email client
until the incoming message is complete.
If you have multiple "X-NAV-TimeoutProtection?:X" entries in the header,
it indicates how long it took to get the complete message from your POP3
incoming mail server. To turn off Timeout Protection, follow these steps:
1. Start Norton AntiVirus 2001.
2. Click Options.
3. Double-click Email Protection, and then click Advanced.
4. Uncheck "Protect against timeouts when scanning email." This will
remove the "X-NAV-TimeoutProtection?:X" header information.
5. Restart your computer.
Installation requires Administrator rights
-----------------------------------------
When installing on Windows NT 4.0 or Windows 2000 you need to have
administrator rights. Logging in as a user and trying to run setup
as an Administrator will not work.
Access privileges required for installation
-------------------------------------------
As part of Norton AntiVirus installation, shared Symantec files, which
are components of all Symantec products, are always installed to
\Program Files\Symantec -- even if a custom location for the Norton
AntiVirus program files is specified during install. If you do not
have write (and create, if necessary) privileges to this location,
the install will fail.
If you are also running older versions of Norton products
---------------------------------------------------------
If you have both this new Norton product installed and any 2000
version Norton product installed on your computer, the
LiveAdvisor button on the menu bar of your 2000 version Norton
product will be removed. As LiveAdvisor is no longer being used for
information delivery, there is no loss of functionality. As was
explained in the final LiveAdvisor messages, Symantec has replaced
the LiveAdvisor delivery mechanism with information on the Symantec
web site (http://www.symantec.com) and product-specific newsletters
(http://www.symantec.com/techsupp/bulletin/index.html). In this way
we can offer information of specific interest to you as quickly as
possible.
Using Norton AntiVirus Email Scanning with Wingate
-------------------------------------------------
Norton AntiVirus email scanner uses port 110 to check incoming email
for viruses. Wingate also uses this port.
To change the port Norton AntiVirus uses, change the following Windows
registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Norton AntiVirus
\eMail Protection\Default Port
Change the value of this entry to an unused port (port 22000 is usually
available). If you enter a port that is already in use, Poproxy (the
Norton AntiVirus email scanner) will not start.
You must also unconfigure all of your email clients and re-configure
them so they will work with the new port.
Even after doing this some email clients, including Netscape, will not
work because they do not support ports other than 110.
Using Norton AntiVirus with Pegasus Mail
----------------------------------------
When using Norton AntiVirus email Scanning with Pegasus mail using
long email address, you may reach the Pegasus 55
character email address limit. To retrieve email again,
disable Norton AntiVirus email protection from this account.
You will need to update your server name and user name in
Pegasus mail.
Using Norton AntiVirus with directory symbolic links/NTFS junctions
-------------------------------------------------------------------
Using directory symbolic links, also known as NTFS junctions,
on Windows NT4 & Windows 2000 machines may increase hard drive scanning
times due to repeat scanning.
Automatic LiveUpdate requirements
---------------------------------
Automatic LiveUpdate requires Microsoft Internet Explorer 5.0 or later
and Microsoft Task Scheduler.
Using Netscape with Norton AntiVirus
------------------------------------
If Norton AntiVirus is installed as a Netscape helper application,
a downloaded file will be lost if Netscape is closed before the
download is complete.
Using Norton AntiVirus with Netscape 6.0
----------------------------------------
Norton AntiVirus Netscape Plug-in does not support Netscape 6.0 due to
the removal of helper application functionality from Navigator.
Using Norton AntiVirus with Netscape 4.x
----------------------------------------
Netscape 4.x uses a feature called Smart Download. This feature is
launched each time you download a zip file and it handles the download
without running it through the Norton AntiVirus plugin. Virus
protection will be provided by Norton AntiVirus AutoProtect when you
extract files from the compressed file.
Print versions of Norton AntiVirus Guides
-----------------------------------------
Print versions of the Norton AntiVirus Users Guide can be ordered
through Symantec Customer Service.
Uninstall Beta versions of Norton AntiVirus
-------------------------------------------
If you tested a Beta version of Norton AntiVirus, uninstall the Beta
before installing the release version. This removes unneeded files
that would otherwise remain on your disk and prevents problems that
could arise due to changed file formats.
LiveUpdate subscriptions
------------------------
With the purchase and installation of Norton AntiVirus 2001, you
automatically qualify for limited free use of LiveUpdate to receive
virus definition updates. Your installed Norton AntiVirus program will
notify you when your subscription is about to expire and provide
information on how to extend your subscription to ensure continuing,
up-to-date protection.
Uninstalling LiveUpdate or LiveReg
----------------------------------
Because LiveUpdate and LiveReg are shared by several Symantec products,
it is not uninstalled automatically if you select Uninstall Norton
AntiVirus. Do not uninstall these components if there is any other
Symantec software installed on your system.
To uninstall LiveUpdate or LiveReg, choose Add/Remove Programs
from the Windows Control Panel and select LiveUpdate or LiveReg.
Quarantining non-deletable files
--------------------------------
Norton AntiVirus cannot automatically quarantine non-deletable files
(for example, files infected by the DirII virus). To manually add
these types of files to the Quarantine, open the Quarantine and choose
Add Item.
Using Norton AntiVirus with non-administrative rights
-----------------------------------------------------
Because Norton AntiVirus is a system-level application, when running
LiveUpdate under Windows NT, you must log in as the same user with
administrative rights as when you installed Norton AntiVirus. When
logged in without administrative rights, Norton AntiVirus will
always consider your virus definitions out of date.
Restart your machine after repairing boot viruses
-------------------------------------------------
We recommend that you reboot after repairing any boot virus on the
hard drive. Some boot viruses, mostly stealth types, subtly confuse
NT and its handling of floppies. Reboot after the repair to ensure
proper operation.
Short File Name (SFN) alias generation during install
-----------------------------------------------------
If you are installing Norton AntiVirus to a custom location that is
a Long File Name (LFN) folder, SFN alias generation must not be
disabled during the install. To re-enable SFN alias generation, run
REGEDT32 and change the following registry key entry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
NtfsDisable8dot3NameCreation should be set to 0 to enable SFN
alias generation.
You must restart your computer in order for changes in SFN alias
generation to take effect. Set the value back to 1 after installation
to disable SFN alias generation, if desired.
Using the /INTERACTIVE switch with the AT command to schedule scans
-------------------------------------------------------------------
You must use the /INTERACTIVE switch to schedule scans with the AT
command. If NAVWNT is launched from the Scheduling Service (AT)
without the /INTERACTIVE switch, Norton AntiVirus remains in memory
with no way of terminating. The following examples demonstrate
correct usage to schedule automatic scans three times per week.
AT 17:30 /interactive /every:M,W,F "c:\Program Files\NAVNT\navwnt" /L
See your Windows documentation for more information on using the AT
command.
Creating a test text file that looks like a virus
-------------------------------------------------
To create a harmless text file that will be detected as a virus,
which you can use to verify detection of viruses, logging, and
alert functioning, visit this site:
http://www.eicar.org/anti_virus_test_file.htm
Disable Auto-Protect temporarily before you save the file.
Uninstalling Norton NT Tools
----------------------------
If Norton NT Tools is uninstalled after Norton AntiVirus is installed,
the shared file S32STAT.DLL is removed. Reinstall Norton AntiVirus to
correct the problem.
Long Filenames and LiveUpdate
-----------------------------
Long Filenames (LFNs) must be enabled to install LiveUpdate.
"Rename Error" during Norton AntiVirus installation
---------------------------------------------------
If you experience a Comctl32.dll rename error when installing
Norton AntiVirus, an error dialog box on your screen shows
the following information:
RENAME ERROR
An error occurred renaming a file "Cannot create a file when
that file already exists"(error #183).
Current File Name: C:\WINNT\System32\Comctl32.dll
New File Name: C:\WINNT\System32\comctl32.bak
To fix the Comctl32.dll rename error:
1) From Windows Explorer, access the following directory:
\winnt\system32
2) Right-click the following file:
comctl32.bak
Select Rename
3) Type the following as the new name for the file:
comctl32.old
4) Run the Norton AntiVirus install program (setup.exe) again.
Disabling email scanning while a download is in progress
--------------------------------------------------------
Norton AntiVirus does not support disabling email scanning while an
email download is in progress. If you do this and if the email that
you are downloading contains an infected file attachment, portions
of this infected file attachment might be left in your TEMP directory
(usually C:\WINDOWS\TEMP or C:\TEMP). It is recommended that you
delete this file. If you should attempt to extract the infected
contents of this file, Norton AntiVirus Auto-Protect will protect you
from any infections.
Inoculation Change Alerts
-------------------------
When responding to an inoculation change alert, you must determine if
the change is legitimate (choose Inoculate to let Norton AntiVirus
generate new inoculation data) or the change indicates the activity
of a virus (choose Repair to let Norton AntiVirus restore the item).
The following examples demonstrate legitimate changes. In these cases
you should choose Inoculate to let Norton AntiVirus generate new
inoculation data.
* Installing or Upgrading Windows
If you are running Norton AntiVirus and reinstalling or upgrading
Windows, you may receive more than one inoculation change alert.
Choose Inoculate, not Repair, to respond to the alert.
Windows modifies boot records during the install operation and
restarts your system more than once. Each time your system is
restarted, these changes are properly detected by Norton AntiVirus.
If you choose Repair, you are undoing some of the changes that
Windows is making and, therefore, corrupting your boot records. You
may not be able to start your system from its hard disk. If this
occurs, start up from a floppy disk and reinstall Windows.
* Partitioning Software
If you use partitioning software (such as Partition Magic) or
drive overlay software (such as Disk Manager and EZ drive), you
may receive inoculation alerts for legitimate changes. When you
set or modify partitions after Norton AntiVirus is installed,
choose Inoculate, not Repair, to respond to these alerts.
For example, Partition Magic may generate several legitimate
inoculation alerts when setting or modifying partitions. If you
choose Repair, your drive may be rendered inaccessible with little
chance of recovery.
Dynamic Volumes on Windows 2000
-------------------------------
Norton AntiVirus does not fully support Dynamic Volumes. Scanning these
drives might result in the error message "Unable to read boot record on
drive." This is because these drives are not bootable. However Norton
AntiVirus will scan the drive for infected files.
Error starting email protection
-------------------------------
If you see the error "Norton AntiVirus is unable to start email
protection. Please ensure that TCP/IP is installed and port 110 is
available," it might be because you are running a firewall program.
If you are using a firewall, the firewall must be configured to allow
Poproxy.exe permission to access the Internet on port 110.
Using Norton AntiVirus with Netscape Previews
-----------------
Norton AntiVirus does not automatically configure Netscape Previews
for email protection. You can configure it manually for email
protection.
Email protection does not work with Eudora 5 beta
-------------------------------------------------
Norton AntiVirus email protection does not work with the beta release
of Eudora 5. Manual configuration does not work.
