Why install Avast Internet Security if I have Avast Free and Windows Firewall?
thanks,
Because it offers a lot more protection levels than avast free + windows firewall.

I have Avast Internet Security. Do I have Safezone and DNS? How can I know if they are enabled? Thanks.
Check the installed components.
control panel > software > avast > change > change
Is this the control panel in Windows or Avast? If they are installed but disabled, how can I enable?
