I am new here, and hope everything properly to make.
I use CIS. How can I block doubleclick? With the old Comodo version this has functioned.
Can you explain your issue more specifically
CG
Double click as in cookies with that name?
One easy way is to go to Blocking Unwanted Connections with a Hosts File and download and install the latest HOSTS file. It will block most doubleclick access, and leave blank spaces on your browser where the ads used to be. 
DoubleClick (doubleClick.net) is a cookie and collects information for others. Example, www.bluewin.ch uses doubleclick.
I have (very simply installed the Hostfiel.
The Hostfile blocks more. It is a pity that I cannot see blocked cookies.
Many thanks sded for help
