Problem: The Sophos shield has a black "X" in it (Mac) or a red dot with an "X" in it (Windows)

Answer: Sophos' AutoUpdate feature is not working or it tried to auto-update and could not. Verify you're connected to the Internet, then left-click Mac) or right-click (PC) on the Sophos shield and tell the program to try and update itself. If it still does not work, make sure the Sophos username/password were entered correctly into the program's preferences (note that the username/password are CASE-SENSITIVE).

Problem: The Sophos shield is grey, not black or blue

Answer: This means that Sophos' on-access scanner is disabled. Please go into Sophos' preferences and re-enable it. If it will not re-enable, you may need to reinstall Sophos to fix it.

Problem: OSX won't allow me to run the installer.

Answer: Go into the "Security & Privacy" preference pane in OSX, and under the "General" tab, tell OSX to allow applications downloaded from anywhere.

Problem: Sophos seems messed up, and just trying to install it over again doesn't work.

Answer: Uninstall what's there first, then try installing a new copy. For Macs, you can find the official Sophos uninstaller in the "/Library/Sophos Anti-Virus/Remove Sophos Anti-Virus" folder. For PCs, launch the "Programs & Features" control panel and locate the two Sophos applications in the list of installed programs. Right click on "Sophos Autoupdate" and select Uninstall. Once done, right click on "Sophos Antivirus" itself and select Uninstall. You will need to reboot your computer after uninstalling Sophos itself.

Problem: On my Windows computers, I can't make any changes to the program's configuration or clean up anything in quarantine.

Answer: You need to give yourself explicit admin rights for Sophos. Go into Control Panels and click on "Administrative Tools -> Computer Management", then select "Local Users and Groups" from the column on the left. Click on "Users", then select your user account. In the resulting window, Click the "Member of" tab. Then click the "Add" button. In the "Enter the object names..." field, enter "SophosAdministrator". Click the "Check Names" button...the field should change to include your computer name and underline everything. Click OK to close the window, then "Apply" and "OK" in the previous window. Now if you quit and re-run Sophos, you have the rights to make changes to the program and clean up files that are in quarantine.
