Sophos AutoUpdate

What is Sophos AutoUpdate?

Sophos AutoUpdate is the updater program which runs with Windows (in the background as a service) and automatically starts up when your computer boots. It checks for updates and automatically downloads and installs them if found based on the user's settings. This is the AutoUpdate service, run as 'System User'.When the service first starts up it performs an update check to the CID.ALSvc.exe runs a scheduler that triggers scheduled updates. It provides an interface that allows an update to be started.

ALUpdate.exe is the file responsible for connecting to the network and downloading files. ALUpdate.exe runs during the update as the system user, but impersonates the local SophosSAU account. See the ‘Significant accounts/groups’section for more details on this user. When ALUpdate.exe is called, it runs with the following parameters: Alupdate.exe -ManualUpdate -NoGUI -RootPath"C:\Program Files\Sophos\AutoUpdate"

ALMon.exe is a DCOM server ("dcomcnfg" - "DCOM Config" - "iMonitor"), which allows Sophos Anti-Virus to display virus alerts to the user desktop. It is launched from the ‘All Users’ Start-up menu (C:\documents andSettings\All Users\Start Menu\Programs\Startup\AutoUpdate Monitor.lnk), and it runs as the logged on user name.


The most used version is, with over 98% of all installations currently using this version. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The main program executable is ALUpdate.exe. The software installer includes 33 files and is usually about 9.92 MB (10,401,277 bytes). SophosUpdate.exe is the automatic update component of the software designed to download and apply new updates should new versions be released.
