When you run the updated version, you’ll notice some worrying changes -- active monitoring refuses to stay turned off, and the privacy settings have been removed in the free version. Avast has also stopped users from being able to quit the software -- yes, really.
If you go into Options and select Monitoring, you can toggle off 'Enable system monitoring' and then turn off Active Monitoring (you can’t turn off the latter without first disabling the former). The problem is, for many people it simply re-enables itself when you restart the program, or after a reboot.
If you click on the corner X to close CCleaner, it now simply minimizes to the system tray. Right-click the icon down there and the only things you can do are open CCleaner, run it, or open Options. There’s no entry to allow you to exit the software.
That means, for most users, CCleaner will run continually in the background, reporting back to Avast. Given that CCleaner is a tool that most people only usually occasionally -- when a system clean is long overdue usually -- switching the behavior so it runs permanently makes little sense.
