Update: Dec. 29
I do see the Firewall in the control panel now. It looks as though the earlier problem of overblocking is fixed. Webroot also provides a "locked desktop" Windows "notification icon" (at the bottom) whenever you use https or go to sleep. That may prevent others from logging on to your machine, in person or even remotely (a problem recently discussed elsewhere).
Also, McAfee Security Scan Plus now returns a green status and recognizes all Webroot components.
