Active Monitoring allows CCleaner Free to monitor your computer in the background so you don't have to have to worry about your PC maintenance. CCleaner's Active Monitor checks for program updates and System Monitoring will check your system and notify you when your computer would benefit from a clean.
We recommend you keep this enabled, but if you'd prefer CCleaner didn't monitor your system, you can turn off Monitoring by following these steps:
- Open CCleaner, then click Options > Monitoring
- Disable System Monitoring by unchecking Enable System Monitoring
- Disable Active Monitoring by unchecking Enable Active Monitoring. Click Yes when the confirmation box appears
CCleaner will no longer appear in your system tray after closing.
