It appears you can only uncheck them on the professional edition.
I sense a great disturbance in the force...
This means what we all feared.. The free version is basically a spy tool and you can't uncheck the spying but rather need to block it with host file or firewall. In which case they KNOW 90% of the free users of it will not even know how to do that. So in effect, it's a spy tool.
Here's a trick if you insist on Ccleaner.. You can install an old version of Ccleaner. Before they had their update channels compromised, before Avast bought them. Before the monitoring crap. It runs just fine. Windows will throw off an application compatibility warning to which you just rename the Ccleaner executable to 1234.exe which bypasses the application compatibility checker.
For me, a combo of Privacy Eraser Pro and Wise Cleaner Free (portable) handles everything nicely. Chrome has Auto History Delete extension which handles all of the extra chrome junk nicely - automatically - on browser close.
