Hello - If I click on Control Panel / Internet Options / Security, my only options are: "Select a zone to view or change settings", and "Security level for this zone" (This is set at medium-high) I do not have the choice to "warn if changing from secure to non-secure mode". I do not have Zone Alarm, but have AVG and Malwarebytes Anti-virus installed, if these are similar? I am running XP Professional.
