Avast says ZyXEL AMG1302 router 'Service Password' needs changing

I have just updated Avast Free and run a quick Smart Scan for threats.

This was clear except for my router, where I got a message not seen before that the ‘weak Service Password’ needed upgrading, together with a button to do it.
This has me somewhat foxed as both the WiFi and Administration access passwords were upgraded by me after the firmware update put out by the ISP, in response to the ?Mirai? attack on the type of router a few months ago. I have gone into the administration section of the router software and cannot see a ‘Service Password’ reset anywhere.

I am reluctant to have the job done automatically if I am unable to access a system to revert if it causes problems.

My question is: what is Avast going to change and where am I likely to find the appropriate section in the admin to see what the consequences are?

If your question is how you can change the default sign-in information on your router,
please use the following search term to get help:
“How do I change the admin password on my NETGEAR router”
Substitute your routers make if it’s not Netgear.

Bob,

As I clearly state in the post I have already changed the ADMIN(istration) password.
What I need to know is what Avast regards as the SERVICE password and how to find and change it.
