Norton Internet Security for Comcast - Live Update or manual install?

Hi - Can someone please clarify?  Will the Norton Security Suite update for Comcast customers be delivered via Live Update, or do we need to install it manually?

 

I did see the pinned topic at the top of the forum.  I asked a  Comcast / Xfinity customer service rep, and he was unsure.  Their support forum also gives conflicting information.  So, I thought I would come to the source to ask.

 

If it matters, my current NSS version is 20.4.0.40, and I'm running Win7 x-64 Home Premium.  I'd appreciate the clarification, as I have several computers (same specs/versions on all) which need updating.  I'd like to set aside some time if I have to update them all manually.

 

Thanks!
