I can't say it is fair to blame Norton. Xfinity has its own suite called Constant Guard. When you install from their site the fist thing they have you download and install is CG. Once that is complete they give you a link to download and install Norton.
I had only installed the CG part when the failure manifested itself again. I just went through installation process again and installed Norton and then uninstalled CG and AutoCAD is rolling just fine.
