Kaspersky and CCleaner

I've been using CCleaner for many years and tried Kaspersky for internet protection and antivirus this year. During the past several months, whenever I use CCleaner, Kaspersky gives me a popup that CCleaner has made a change to my browser and Kaspersky has set it back to where it was.

I don't know what is being changed and changed back.

Also, although I have CCleaner set to the default settings, I never see any logs or temporary files being erased and I wondered why they don't appear in the window which shows what has been erased?

Thanks!
