CCleaner uses system monitoring and “Intelligent Cookie Management”

Most free software and tools install unwanted settings or other software by default unless you read what is taking place during its installation. The very commonly used CCleaner system-cleaning tool is no exception. The images provided below show what it now does that I, for one, don’t want to take place. Click on the images to see them in full size.
CCleaner might install McAfee security software or Google Chrome as your default browser – the one that the system uses automatically – unless you disable the option(s) before the installations take place. It’s August 2016 and I have not seen the Chrome default installation for a long time, but have seen the McAfee option recently.
CCleaner: Active Monitoring and Intelligent Cookie Scan
There is a setting called “Intelligent Cookie Scan” that only removes cookies that it considers are not wanted, but probably leaves the tracking cookies that its sponsors, such as Google, want left in place. I choose to disable that setting because it can’t be disabled after the installation (I am suspicious of an optional setting that disappears from the settings). It can only be disabled by reinstalling CCleaner.
During the installation CCleaner presents its active monitoring options. Since Google must be sponsoring the tool, I disable system monitoring because the results are probably returned to Google.
If you choose to disable Active Monitoring during the installation, a warning is produced saying that this is not recommended because CCleaner will not update itself automatically and won’t be able to provide active protection – from what? The tool only removes rubbish, it is not an anti-malware scanner. I ignore the warning. The tool wants to be updated every few weeks, which is ridiculous. I update it two or three times a year – manually.
