Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
So if you navigate to the folder described, you don't see the AVWiz12s.dotm?
Try going to Office button / Word Options button / Addins command. Look throught the list of apps/addins for something that looks related to "AV Wiz" the "12" could mean Office 2007. I haven't figured out how to use this list to disable an addin (maybe someone else can say). An alternative is you can download this applet: http://www.nirsoft.net/utils/officeins.html
It allows you to control, ie disable office addins.
