CCleaner automatically cleans too often

I love the CCleaner and have for years. I have the pro version v4.19.4867. My computer is running Windows 7 Pro 32 bit.

My problem is that the cleaner starts on its own way too often, several times a day. I went through the settings to no avail. I must be missing something? I want to use the cleaner when I want because there is no reason to have it running all the time.

Please help me stop an overactive CCleaner.
