Hello, thank you for a prompt reply.
I recently purchased a refurb Lenovo TinkPad w windows 10 pro.
I added Avast Premium for security.
Avast found port 7547 open..on Xfinity account I See I have an Arris TG1682G. I could port forward etc. But as I plan to use this Computer for business purposes, I need the security .
do not have my own hardware router yet, but want to close this port.

I'm having the same issue. Avast says having port 7547 open creates "needlessly large attack surface," and I'd like to follow their suggestion and close it. I just can't figure out how.

Does that imply the Arris DG1670A software doesn't allow us to modify which ports are open or closed? I'm with Spectrum/Time Warner, btw.
