Sidesync app is loaded on my Verizon Samsung Galaxy Note 4 and my Windows 10 PC. When i attempt to open Sidesync on my PC, a popup opens telling me that i must close "Verizon Wireless SUA before Sidesync will open." How do I close SUA?
That's the software upgrade assistant. Did you download any of the software update apps to your PC at some point? If so, you should be able to close them in your Windows Task Manager. If not, then it could be a false flag from Sidesync.
