1.This is something that I do not know but would also like to know.
Go to Advanced Settings.
Navigate to “Configuration” in the left menu.
Expand the arrow at the bottom of the window or right-click anywhere in the field with the configurations.
Navigate to the place where you installed Comodo Internet Security, for me it’s “C:\Program Files\COMODO\COMODO Internet Security” then choose the configuration you want out of Firewall, Internet and Proactive Security.
Name it to what you want to call it, don’t change the name if you want to overwrite the older configuration.
Either click the configuration then click “Activate” on the bottom options bar or Right-click the configuration and click “Activate”
If it tells you to reboot then do so.
2. If it is secure I do not know but you can add C:\VTRoot (it’s hidden) otherwise you can use the “Reset Sandbox” function in CIS to reset the virtual kiosk, at least I think it resets the virtual kiosk, it should. I would recommend using the reset sandbox feature in CIS.
