While the CCleaner Active Monitoring feature offers a great and easy way to clean up junk files, at times, like this, it can really come across as a major irritant. A simple solution to deal with this situation is to turn off Active Monitoring if you do not prefer CCleaner monitoring your system.

Launch CCleaner and select ‘Options’ from the main screen of the program. Next, choose ‘Monitoring’. Then, from the following three options listed- Un-check the box marked against ‘Enable Active Monitoring’. Hereafter, CCleaner will not appear in your system tray after closing. But is will start monitoring on computer restart! You now need to disable Active monitoring via its Settings and then disable the CCleaner startup entry using MSCONFIG. There is another thing you need to know. You cannot now close CCleaner using the ‘x’ button. When you click on ‘x’, the program just minimizes itself to the notification area. You need to kill the program using the Task Manager. In response to this, CCleaner has said: TIP: During installation, CCleaner offered to install Avast antivirus on my PC. I missed that part and it got installed. I had to uninstall it. So do remember to opt-out of such an offer. You spoke, we listened. Here’s what we’re doing: We will separate out Active Monitoring (junk cleaning alerts and browser cleaning alerts) and heartbeat (anonymous usage analytics) features in the UI and we will give you the ability to control these individually. You will have the options of enabling all, some or none of these functions, and this functionality will be uniquely controlled from the UI.We will take this opportunity to rename the Advanced Monitoring features in CCleaner to make their functions clearer.We will deliver these changes to the software in the coming weeks.
