2 or 3 times in several days my firewall has said SupportSoft Agent Service
wants into my trusted zone (LAN stuff - none of which is even being used on
my system).

Having no clue what SupportSoft Agent Service is I Google it. Everybody's
talking about it but nobody is defining it. (Eventually I discover that
Comcast installed it.) Several sites say it is or is related to related to
an SNMP based agent - which I'm sure everyone here has for breakfast, but
.... Again everybody's talking about it but nobody is defining it.

A found that this thing is in the Comcast "Desktop Doctor" folder and even a
Comcast CHAT technician said I'd be better off deleting Desktop Doctor.
Frankly in the few days I've had Comcast (my only choice) broadband, I've
come to trust them as far as I can throw a Mexican bull by the tail.

Is it possible to tell in simple English what this thing is really doing on
my computer and why it wants access to my trusted zone. And/or why I
shouldn't permanently disable it.
