What is this update to an Application List?

What is this process when during an install or update to CSC V2, an install and update to a certain application list is performed? It seems to be going through all my applications I have installed on my PC.


When CSC updates the application database, it will check your installed applications and download the updates for that applications. An update for an applications means a list of registry keys and files that the application creates and are safe to delete. A new update means basically that we found more entries that can be safely deleted from the application.
For Disk Cleaner and Registry Cleaner, only junk entries are deleted. For Privacy Cleaner we delete user specific files or registry keys.
None of this will affect your application behavior.

or block the program with your firewall! :P0l
