AVAST Upgrade utility

I jus upgraded my Windows 7 to 10 and I have a 360 Total security anti virus program that I am very pleased with. But now this Avast window keeps popping every 2min and it crashes for a minute or so every time it comes up. It keeps asking me install the latest Avast antivirus but I dont want it. There is an option to postpone it 10min, 1hour, 4,hours and Never but it doesnt work and it just keep popping up. Its pissing me off! How do I turn it off???!!!
