So I recently upgraded to Avast Internet Security and was wondering if I could disable Windows Defender. Although Avast says everything is running, Windows tells me I have no virus protection and should re-enable Defender. In the control panel under security and virus protection, I can view installed antivirus apps, but cannot enable Avast. Does this still mean Avast is working or do I actually need both running?

P.S. I am running Windows 10 1607
