How to disable CCleaner automatic scans at startup ?

Hello,

I'm new and I don't know much about CCleaner. It was pre-installed on the computer I bought. My PC runs Windows 7 64-bits.

Every time I turn on my PC, CCleaner does an automatic scan. It takes some ressources, I can see the CPU % up in windows task manager when it's running and as soon as the alert window 'CCleaner can clean X amount of data' pops up, CPU % is back to normal.

Basically I'd like to disable these automatic scans at startup and just perform manual ones whenever I need to. I do not want to stop CCleaner from launching in the background at startup, I just want to disable automatic scans on startup.

I went through the options today but didn't find how to turn it off. Anyone can help ?

Thanks in advance.

In ccleaner's settings turn off all monitoring setting, including keep updated.
