Sophos Update is a utility that enables the automatic updates
of IDE
for Sophos Anti-Virus. The software was develloped for Windows 2000/XP
and
Windows 98/ME.
March 2005 Sophos came with a new version version of
Sophos
Anti-Virus (v 5.x) that supports automatic updates. This
utility cannot be
used for this new version, because home users can also update
directly
from the Sophos update servers. Sophos Update can only be
used for
the 3.x versions of Sophos Anti-Virus for Windows 98/ME/NT/2000/XP and
2003.

Some company's did not implement an update server to alow home users to
update
there anti-virus software. Sophos offers the RemoteUpdate product, but
this only
works in combination with an Intranet connection and a Installation
point
maintained with Sophos Enterprise Manager.
Most home users only update there anti-virus software once a month.
Updating
new released identities (IDE's) is difficult and time comsuming process
that is
not suitable for must home users. Sophos recomments using a batchfile
and WGET
to update Sophos. This concept is used bij Sophos Update.
Windows XP will report that Sophos is OUT OF DATE when SP2 is installed and you did not update the monthly version. In fact Sophos is UP TO DATE as long as the download for new IDE's is supported.
Yes, Sophos update only updates IDE files. You still need to update the monthly released, but you do not need to update the IDE-files any more. After updating the montly version of Sophos it is recommended to perform a manual update (right-click->Update now!). Sophos supports IDE's for 3 months on older versions.
Sophos Update can automaticly update under
different certain
conditions. All update options are enabled by default, but can be
turned off.
The following table shows the possible options and when they are useful:

On Windows NT4/2000/XP Sophos Update is installed as a service. When
the
service is running, all update tasks are performed by the service. In
that case
the application in the system tray is only used to notify about updates
and to
enable to change the settings. You can disable
the system tray
application by toggeling 'Start program at startup/login'
in the
Settings menu of the settings/status dialog (double click the
notify icon
of use the context menu), disabling this option does not deactivate the
Sophos
Update service. If you installed Sophos Update with an other
useraccount and
you want to enable the system tray application, you need to select the
option
'Everyone ' at installation. When logged on as an other user you need
to start
'Sophos Update' from to start menu and manually select the startup
option from
the menu.
For Windows 98/ME the system application also performs the updates, and
should
be started when the computer starts if you want automatic updates.
Sophos Update uses the downloadable ZIP-files from www.sophos.com. First the version of Sophos is determined, then the corresponding ZIP-file is downloaded and expanded. For each IDE-file the existence is checked. The IDE is installed if it is not installed yet or is updated if the existing IDE-file is older than the new one. After updating the IDE files, Sophos Update will try to restart the Sophos Service (NT/2000/XP/2003) of the Intercheck process (W98/ME). Updates will not be performed if Sophos Update detects that Sophos Anti-Virus is in setup mode. This makes Sophos Update useful for laptop users even when automatic updates on the corparate-network are enabled.
When running Sophos Update on NT4/2000/XP or 2003, Sophos Update is installed as a service. Updates, trigger information from the system tray application is communicated using a registry value under the LOCAL_MACHINE hive. To be able to change settings you must be able to write the registry keys under HKEY_LOCAL_MACINE\Software\JBSoft\SophosUpdate. By default a normal user account will no be enabled to change these registry values.
From version 1.1.7 Sophos Update supports the detection of a new available version. When updating IDE's Sophos Update reads the version of the currently installed Sophos product from the registry. Then the ZIP-file belonging to this version is downloaded to update with the correct set of IDE's. Once a day after about 5 minutes of runtime Sophos Updates tries to download zip-files for higher version of Sophos Antivirus. When this is succeding, the will be a new version available of available soon. Sophos Update will blink it's notify icon and will report to eventlog and with a balloon message (not for Windows 98) at the systray (when notifications are enabled only).
