How do I view the log for my Sophos client?
Right click on the blue Sophos shield that should be in your System Tray and select, Configure Updating, from the pop up menu. In the “Properties for Sophos Autoupdate” box, select the tab labeled, Logging. There is a button on the Logging tab labeled, View Log File. In that log file you will be able to see the status of the auto-update process and the server from which it is successfully receiving updates.
