I use Windows XP and Comodo Antivirus 7. I use Windows as administrator only.
When I start a program in the sandbox, fully virtualized, what about its privileges? Do they remain high? Do they drop to limited?
By default they run with the same access rights as the user who executes it, so with admin rights in your case. However, you can configure the auto-sandbox to run fully virtualized and with access restrictions see here Configure Rules for Auto-Sandbox, Sandbox Security Software | internet Security
That is not applicable, at least in Comodo 7.
I realized that when a program is fully virtualized it’s not possible to apply access restrictions, and if we apply access restrictions it’s not possible to use fully virtualization. The user must choose between the two options.
