Bouncy Ball

You might get a warning like "Bouncy Ball Installer.zip is not commonly downloaded and may be dangerous".You can select "keep". Again, when you try to install it, you might get an alert saying "Windows protected your PC".

 The reason it does this is because windows does not detect this file as a common one, and since it could contain a virus, trying to prevent you from running it.  However, this is just a game and can't harm your computer.

You can click on "more info" and then "run anyways". After that you can just click Next for everything, and also be sure to select "create desktop shortcut".
