2. General notes
----------------
a) Archive types
Archives are not scanned by default. To enable archive scanning, select it
within Sophos Anti-Virus. Depending on the number of archives present,
scanning time may be increased.
Selecting archive scanning enables the scanning of ARJ, CMZ, GZIP, RAR,
TAR, UUE, ZIP, LHA, LZH archives, self-extracting archives of these types,
zipmail files, and files compressed with MS Compress.
Self-extracting archives are only scanned as archives if archive handling
has been switched on for that archive type. Otherwise they will be scanned
only as executables.
If both archive scanning and Macintosh virus scanning are selected BinHex
and MacBinary files will also be scanned.
Unix ELF files are scanned either when their file extension is in the
executables list, or if 'All files' is selected.
The scanning of Microsoft Cabinet files is not enabled when archive file
handling is enabled. It can be enabled individually.
b) Extension list
The following file extensions are scanned for by default in immediate and
scheduled scans.
..., 386, 3GR, ADD, ASP, BAT, CHM, CMD, COM, CPL, DBX, DLL, DMD, DOC, DOT,
DRV, EML, EXE, FLT, FON, FOT, HLP, HT?, HTA, HTML, I13, IFS, INI, JS, JSE,
LNK, MOD, MPD, MPP, MPT, MSO, NWS, OCX, OV?, PDF, PDR, PIF, PL, POT, PPS,
PPT, PRC, RTF, SCR, SH, SHB, SHS, SRC, SWF, SYS, VB?, VXD, WBK, XL?,
3. Additional information
-------------------------
The following suggestions may require the use of the Registry Editor
(REGEDT32.EXE). Microsoft have issued the following warning with respect to
the Registry Editor:
"Using Registry Editor incorrectly can cause serious, system-wide
problems that may require you to re-install Windows NT to correct
them. Microsoft cannot guarantee that any problems resulting from
the use of Registry Editor can be solved. Use this tool at your own
risk."
a) System requirements
This version of Sophos Anti-Virus for Windows NT/2000/XP requires Windows
NT 4.0 or later. It will not run on Windows NT 3.51.
b) Restarting after an InterCheck upgrade
If the InterCheck driver has been upgraded, after upgrading from a previous
version of Sophos Anti-Virus for Windows NT/2000/XP, the system must be
restarted before the new InterCheck driver is activated. Restarting your
system immediately after the upgrade is not necessary. InterCheck will
continue to operate correctly, and the new features will be activated next
time the system is restarted.
c) Setup
'SETUP /UPDATE' has priority over workstation installations,
i.e. 'SETUP /UPDATE' will not fail because a workstation is in the process
of establishing the need to upgrade or is in the process of upgrading.
Several command line qualifiers have been added to the setup program:
-a non-interactive install
-updaccount=domain\username\password update account info
-ni non-interactive setup
-in invisible setup program
-inl invisible loader
d) Compatible with 'Terminal Server' and 'MetaFrame'
This version of Sophos Anti-Virus for Windows NT/2000/XP will run on
versions of the Windows NT operating system which support multi-user
emulation. To provide this functionality, the graphical elements (Sophos
Anti-Virus Graphical User Interface and InterCheck monitor) should only be
run on the main console. This behaviour is automatically enforced when NT 4
service pack 4, or later, has been installed on the server.
e) Messaging sub-system
It is possible to inhibit the display of a desktop message issued by the
InterCheck Client as it shuts down. To do this add the following value to
the registry:
Key: HLM\SOFTWARE\Sophos\SweepNT\SMMs\Desktop.smm
Value Name: Shutdown Message Action
Type: REG_DWORD
Data: 0x0000000F
It is possible to force the SMTP SMM to send its reports as MIME-encoded
attachments. To do this add the following value to the registry:
Key: HLM\SOFTWARE\Sophos\SweepNT\SMMs\SMTP.smm
Value Name: Mime Encode
Type: REG_DWORD
Data: 0x00000001
Files in off-line storage are reported. To suppress these messages add the
following value to the registry:
Key: HLM\SOFTWARE\Sophos\ADVANCED
Value Name: REPORT_OFF_LINE_FILES
Type: REG_DWORD
Data: 0x00000000
Encrypted files are reported. To suppress these messages add the following
value to the registry:
Key: HLM\SOFTWARE\Sophos\ADVANCED
Value Name: REPORT_PASSWORD_ENCRYPTED
Type: REG_DWORD
Data: 0x00000000
f) Interaction with files held in off-line storage
By default, during immediate and scheduled scans, Sophos Anti-Virus will
not retrieve files marked as being held in off-line storage for scanning.
This default behaviour can be over-ridden by setting the following value in
the registry:
Key: HLM\Software\Sophos\ADVANCED\
Value Name: SCAN_FILES_IN_HSM
Type: REG_DWORD
Data: 0x00000001
By default, during immediate and scheduled scans, Sophos Anti-Virus will
reset a file's last accessed time. This default behaviour can be over-
ridden by setting the following value in the registry:
Key: HLM\Software\Sophos\ADVANCED\
Value Name: RESET_LAST_ACCESSED_TIME
Type: REG_DWORD
Data: 0x00000000
g) Log file handling
The log file may become very large. It is not possible to delete SWEEP.LOG
while the service is running. However, if the location of SWEEP.LOG file is
changed the original can then be deleted.
h) SNMP Notification
There is a messaging module for SNMP trap generation. Four types of traps
are possible. They are assigned OIDs (object identifiers) as follows:
1.3.6.1.4.1.2604.2.1.1.1.1 Virus warning
1.3.6.1.4.1.2604.2.1.1.1.2 Error message
1.3.6.1.4.1.2604.2.1.1.1.3 Informational message
1.3.6.1.4.1.2604.2.1.1.1.4 Test trap
Each trap carries a SAV version string and an informational string giving
the nature of the alert.
Data are assigned OIDs as follows:
1.3.6.1.4.1.2604.2.1.1.2.1.1 Virus warning text
1.3.6.1.4.1.2604.2.1.1.2.1.2 Error message text
1.3.6.1.4.1.2604.2.1.1.2.1.3 Informational message text
1.3.6.1.4.1.2604.2.1.1.2.1.4 Test trap string
1.3.6.1.4.1.2604.2.1.1.2.2 Version string
Note: it is impossible to remotely query the MIB. The data are only
available from the contents of the trap.
i) Virus information
When requesting information on viruses, users are directed towards the
Sophos web site for the most accurate up to date information.
4. Information from previous versions
-------------------------------------
December 2002 (3.64)
* An installation and updating problem on Windows 2000 with Novell
IntraNetWare Client version 4.8x has been resolved
* InterCheck has improved support for roaming profiles on Windows 2000.
The change to version 2.19 of InterCheck will prompt for a reboot of the
computer, but a reboot is only necessary if you are affected by the roaming
profile issue
* MailMonitor for Exchange 2000 will install correctly with this version
* SAV Interface has some minor compatibility fixes
October 2002 (3.62)
* InterCheck monitor icon colour change indicates InterCheck inactivity
The InterCheck Monitor arrow will now change from its usual red to grey to
indicate that InterCheck is disabled.
* Alternative data stream scanning
Alternative data stream scanning is now featured in on-demand immediate and
scheduled scanning. It is already provided by InterCheck on-access scanning.
* SAVI DLL now runs on both Windows NT/2000/XP and Windows 95/98/Me
SAV Interface (SAVI) developers will now be able to write products that can
be used on Windows 95/98/Me to complement those already available on Windows
NT/2000/XP.
* Running SAV Interface third-party applications
SAV Interface (SAVI) has been modified to allow third-party SAV Interface
applications to be run as non-administrators.
* Ability for Setup to remove unwanted shortcuts from the Start menu
Sophos items that no longer exist on the computer but appear in the Start
menu will now be removed.
* Purging checksums on restart
Due to the frequency of virus updates InterCheck's checksums are now
automatically purged after each computer restart.
* Autoupdate frequency settings
Information on autoupdating and its frequency is now transferred to local
installations during updating as well as during installation.
* New information pages
There are new information pages available on this CD. You can view these
pages from any computer with an internet browser installed. They include
installing and updating advice, product information, documentation, and
contact information.
Windows (Intel) users
To view these pages, let the CD autorun or run 'LAUNCHCD.EXE' from the
root of the CD. If Internet Explorer 4.0 or above is installed on your
computer, the information pages are displayed in a special Sophos
application that enables you to install or update directly from the
information pages.
Windows (Alpha) users
LAUNCHCD.EXE will run Internet Explorer as a browser only if autorun is
enabled. You will not be able to install or update directly from the
information pages.
Other browsers
With other browsers open 'index.htm' from the root of the CD. You will not
be able to install or update directly from the information pages.
If you have any difficulties viewing the CD's information pages, email
sophoscd@sophos.com.
September 2002 (3.61)
The checksum file is now purged on restart.
Auto-updating has been improved for non-English workstations.
5. Known problems
-----------------
a) SAV Interface (SAVI)
Developers may set the maximum recursion depth configuration option.
Re-configuring SAV Interface client applications while they are active
fails.
b) NetWare server and Windows 2000 workstation
This problem affects only the running of the setup /update program on
Windows 2000 computers when the Central Installation Directory is based on
a NetWare server.
When it is necessary to place a new IDE file in a Central Installation
Directory (CID) based on a NetWare Server and to run setup /update on a
Windows 2000 workstation, the following command line should be used instead
of the documented command:
setup /update /srcpath=\\netwareserver\cidpath
where \\netwareserver\cidpath is the full UNC path to the CID.
c) InterCheck server and Windows 2000
InterCheck server is selected by default on Windows 2000 installations. It
should be deselected during installation when not required.
6. Troubleshooting
------------------
a) Errors accessing network shares from remote computers
After installing Sophos Anti-Virus for Windows NT/2000/XP, you may
encounter difficulties accessing network shares from remote computers. You
may also receive one of the following error messages:
"Not enough server storage is available to process this command."
"Not enough memory to complete transaction. Close some applications
and retry."
Additionally, the Windows NT server may log one or both of the following
event messages in the system log:
Event ID : 2011
Source : Srv
Description : The server's configuration parameter "IRPStackSize"
is too small for the server to use a local device. Please increase
the value of this parameter.
Event ID : 0
Source : Srv
Description : Description for Event ID 0 could not be found. It
contains the insertion string \device\LanManServer.
This is a restriction imposed by the default Windows NT server
configuration. The following registry entry is required to solve the
problem.
Key: HLM\SYSTEM\CurrentControlSet\Services\LanmanServer\
Parameters\
Value Name: IrpStackSize
Type: REG_DWORD
Data: 0x6
You can use REGEDT32 to modify or create this entry in the registry. You
will need to restart the system before the change will take effect. If you
still experience problems, a larger value can be selected. The valid range
for this parameter is 0x1 to 0xC (1 to 12). Please see the Microsoft
knowledge base article ID Q198386 for further information.
b) SWEEP for Windows NT Update service
To function correctly, the auto-update service must be installed as the
'LocalSystem' account and have 'Allow Service to Interact with Desktop'
selected.
c) InterCheck logging
For InterCheck logging to work correctly, the SWEEP for Windows NT Network
Service must use an account that is able to see the InterCheck Server
share. This may not be the case if the auto-update option was not selected
during installation.
If InterCheck logging fails to work correctly, a suitable account may be
selected as follows:
* Go to Control Panel|Services.
* Select the SWEEP for Windows NT Network Service.
* Click the 'Startup...' button.
* Under 'Log on As:', select the field 'This Account'.
* Enter an account in the form DOMAIN\User with access to the relevant
InterCheck Server share.
* Fill in the password field as appropriate.
* Click 'OK' to confirm the change.
* Stop and then restart the service.
7. Compatibility issues
-----------------------
a) Banyan VINES support
Please note that InterCheck will not check files on remote Banyan VINES
drives unless the Banyan VINES network support was started at start up.
b) PATHWORKS Version 4 server
Windows NT clients which use a PATHWORKS 4 server for the central
installation directory may repeatedly auto-update. This problem only occurs
on PATHWORKS 4 not on later PATHWORKS versions.
c) Bay Networks (Performance Technologies) Instant Internet
A conflict between the version of the WinSock client installed by the
Instant Internet application and the Sophos SMTP.SMM module can lead to the
Sophos Anti-Virus service not starting or stopping correctly.
As a work-around, add the following value to the registry.
Key: HLM\Software\Sophos\SweepNT\SMMS\SMTP\
Value Name: No Startup Check
Type: REG_DWORD
Data: 0x1
This work-around will prevent the SMTP module checking for the appropriate
network transport protocols during startup.
