Router not set up properly???

My Avast keeps telling me that my router, an Arriss, supplied by my ISP, is not set up properly. What the heck does that mean, and what is to be done about it?MHJXK

What part of avast is saying it ?
Screenshot can help.

Honestly…I would not listen anything any software would tell you about your routers setup, it’s all up to your personal desire and preference and routers manufactures firmware updates and suggestions

Pretty bad advice. :o If I followed your advice, I could let the crooks into my system without ever knowing about it.
