It is not possible anymore to disable Active Monitoring in CCleaner ,
even if you uncheck it in Advanced options.
I removed CCleaner from Windows startup, killed CCleaner process in Task Manager, but
after Windows restart Active Monitoring is back with icon in system tray.
So, for now I'll use 5.44 version, but I'll check Privacy Eraser.
BTW, I didn't have problem with advertising since I blocked all .exe files from installation folder with Windows Firewall.
