Internet connection?

Why, whenever I click the Run Cleaner button on the GUI, does CCleaner want to make an internet connection?

This should not occur. Did you get ccleaner from piriform's website? What version of ccleaner. What is pointing you toward saying it's making a connection. Maybe you're clicking on run cleaner directly after opening the program and it's checking for updates still.

From both CCleaner website and FileHippo when using the GUI updater.

5.38 and 5.39.

Firewall notification.

When running installer; first TCP PING command runs, then CCleaner Installer attempts connection, then CCleaner Emergecy Updater attempts connection.

After installation; when CCleaner GUI is opened, a UDP connection attempt is made.

I have disabled CCleaner Updater and deleted the Updater executable and it continues to attempt UDP connection.

This is expected behavior with the latest versions. CC gathers some usage statistics and sends it home. Confirmed with CC support. If this is bothering you, you can block it with a firewall rule.
