I have uninstalled FlashPlayer from my Windows 10/Firefox desktop computer but there is a contining always there large FlashPlayer Logo box on all screens in the lower right corner that obscures everything under it. I can't get rid of it. Can you help?
If the Flash logo you're referring to looks like the one in this screenshot, it's because some software you have installed requires Flash Player. Once you uninstalled Flash Player, it displayed this icon because it can no longer find Flash Player. Once such program is Smilebox. There may be others, but Smilebox is one the Flash Player community has identified and the most widely reported on these forums.
