Piriform quickly released a new build (4.18.4844) as a result of the confusion that the Active System Monitoring caused in the last update (4.18.4842).


Active Monitoring can now be disabled by:

1. Open CCleaner, then click Options > Monitoring
2. Disable System Monitoring by unticking the box next to "Enable System Monitoring"
3. Disable Active Monitoring by unticking the box next to "Enable Active Monitoring", and click Yes when the confirmation box appears
