I deleted Corel Painter from my iMac because I was so annoyed by the ads. I'm still getting the ads after deleting the software!!!! TELL ME HOW TO DELETE THESE ADS!!
iirc it's the corel cuh process plugging them in, there's a guide on locating it here:
you have to delete it and reboot the mac afterwards. it should be gone.
I recall there used to be a more specific guide on removing the adware corel installs alongside with the painter app, but I can't find it anymore.
