Sophos has stopped updating
If you can see the blue shield when you do this then everything is running normally.However because the shield is hidden it does mean that you are more likely to miss problems with your Sophos installation.Right-click on the Oxford Sophos Antivirus Installer screen and select Once complete you should have a file called on the desktop.The Oxford Sophos Antivirus Installer window will display instructions together with an email address.in the Windows system tray (usually bottom-right of the screen, near the clock) then Sophos is running properly. To view the shield on Windows 7 see the answer to the question Why can't I see the Sophos shield in the Windows system tray or OS X system status bar (near the clock)? Sophos for Mac OS X On OS X the shield appears in the system status bar (usually top-right of the screen) and is black rather than blue. The Sophos client updates automatically via the Internet - you don't have to update it yourself.Depending on the version of Sophos the shield may be solid (version 7) or appear as an outline (version 8). The current Sophos client will continue to update automatically until November 2012 at which point you will have to download and install a new version of the software.On the Mac, Sophos for OS X version 8 runs on OS X 10.4 - 10.8.For Linux system requirements see Sophos Anti-Virus for Linux: system requirements.
I have always really liked Sophos as a product, and a company, but I am finding this very frustrating, and more to the point - worrying, as my PC is not protected.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.I also tried navigating to the \Sophos Update\CIDs\S000\SAVSCFXP share and re-installing, which it attempts to do, but also fails.Then I tried uninstalling the AV, Auto Update and Remote Management System from Programs and Features, but either it tells me it's still in the middle of another install (the failed Sophos update) or else, (after a reboot), it tells me I have insufficient privileges to uninstall the software!
If you want to switch to using Sophos instead you should first uninstall the other product using the menu.
