Comcast has been providing a free version of the MacAfee security suite to its customers for about a year now. The product actually worked well and it truly was free (granted, you are a paying Comcast customer) and never got pesky about an up sell of any sorts. In fact, there were no ads at all, which was quite refreshing.
I noticed today that Comcast has swapped out the Norton Security Suite product for the former MacAfee suite. I do not know why they did this, but as a paying Norton subscriber on my work laptop, I jumped at the chance to test the free Comcast offering out.
After a quick run through of all of the parts and pieces this product appears to be the real deal. If you are currently a Comcast customer you should check it out. After all, you are paying for it whether you use it or not.
