I just really liked the Netgear documentation on how to fix some of the non-obvious default settings to be less vulnerable.

I have done some tech-writing and this was awesome! So, whoever did it, great job!

And how is that related to Avast support ???

I guess the OP means this https://help.avast.com/en/iws_ios_free/1/netgear/howto_unsecured_wifi.html or another related article

In that case, I have to agree with the OP. Those instructions along with many other helpful instructions pertaining to network and router security,
make the help Avast offers very complete if you have a security problem checked by the Wi-Fi Inspector.
