Comcast Free Version

I am trying to help out a friend who uses Comcast Free Version of Norton, I believe they give you the Internet Security. I want to be sure he has the latest version. I have used chat with Comcast and Norton and they could not tell me of a web site that I could check to see what it is. I would like the web site so we could check back on a regular bases to be sure we are current. Also is there a way to find the current definitions on the program and a web site to be sure that is correct. I believe he said it only shows the last time it was updated but no def version or number. I believe the version started with a 3 and see where the paid version does not. Not sure about this will not see his computer till tomorrow. Would like all this information so when I look at  his computer I will know he is up to date. Thanks sly53
