Hi Python

I take it Comcast is your Internet Services Provider and MaAfee is the security software as part of your package. McAfee is a perfectly adequate security suite that will give you the necessary protection from "nasties" on the net. It is not free however as it is part of the Comcast subscription you have to pay.
Previous posts were asking about free products that were not tied to any other deals and Avast & AVG have been the best around for several years.
