On systems running Windows 7 the display options for the system tray icons are different and as a result you may rarely if ever see the shield.However if Sophos is running normally you should be able to see the shield by clicking on the double up-arrow near the clock to display any hidden icons.We recommend that you change the settings so that the shield is always visible as follows (this isn't an issue on Windows XP and Vista).To change the settings select We are currently distributing Sophos Anti-Virus for Windows version 10.0, Sophos Anti-Virus for Mac OS X version 8 and Sophos Anti-Virus for Linux version 7.5.Note that problems with a departmental or college computer should generally be referred to your local IT Support staff.If you are looking for information about the Flashback/Flashfake virus infection on Mac computers please see our Flashback page for removal tools and other information about protecting your machine and data.This indicates a problem which needs to be investigated and fixed. Sophos will normally also display a message box to show you what the problem is as shown below. Blue and white shield with red circle and white cross If you see a red cross (some may notice that it's really a white cross on a red background) on the shield it means that the last time that Sophos tried to check for updates, it failed for some reason, perhaps because it does not currently have the required network connection. This is often seen if you are using a USB modem for your broadband connection.
If you have any questions about the software and how to install or operate Sophos that is not in the Windows Instructions, Mac Instructions or Linux Instructions, and that is not answered below, refer to your local IT Support or contact the Help Centre.
On Windows and OS X systems Sophos puts a shield icon in the system tray near the clock (Windows systems) or the system status bar near the clock (OS X systems). Solid black shield with cross in the centre On OS X systems running Sophos version 7 then if updating fails then you'll see a black shield with a cross in the middle of it. IT Services makes this new version available by the beginning of Michaelmas term every year.
The shield can appear in a variety of colours, and can have additional symbols superimposed on top of the shield. Blue and white shield with yellow triangle and exclamation mark You will see this on Windows systems running Sophos for Windows version 10 and above. NB when you download the Sophos client you will automatically be registered on the sophos-users mailing list.
If you want to switch to using Sophos instead you should first uninstall the other product using the menu.
If you have uninstalled any other antivirus software and still have problems installing Sophos then you will need to send us some log files to help us figure out what has gone wrong.
If your computer is not connected to the internet you should expect to see updating fail.
