How do I disable the banner in the upper right of the screen?

Whenever I close a browser, and at random moments, CC Cleaner posts a large banner bragging about how much it has cleaned (frequently "0"). This banner is large and so obtrusive that it blocks my work. I bought the program because I thought it worked silently in the background, not screaming for attention.

I cannot find the option to stop this - short of uninstalling the program and going elsewhere.

Has anyone found a way to disable these notifications?

Thank you!!
