How can I stop the pop up screen that Abode or some entity wants to write files on my computer?

Since installing the Adobe Flash Player ActiveX 11, I keep getting these annoying pop-up screens that wants to write files to my computer. How can I stop these pop-ups? when I uninstalled Adobe Flash Player, then I could not get my videos or PCH games to work correctly. Everything was just fine begore getting the installation notice from Adobe to download this file.
