Utopia.net Hijack DNS, Avast Antivirus

[raprap]

Hello,

This is a repeat subject, the last thread I reviewed is two years old.

Utopia.net has hijacked my network, it's now utopia.net as I see with IPconfig and with Avast Network analysis. I am told that the Premium version of Avast will address this but must remove Norton. (I have spent hours on chat with 3-4 norton reps, useless.)

Does anyone have current experience with this?

Also, Avast free version reports

Open port reachable 7547

HNS-WAN-ACCESS

I don't see anyway to pmanage ports in the router execpt for port forwarding. 

Gateway is:

Model:X5001

Vendor:ARRIS Group, Inc.

Hardware Revision:V02

Appreciate any and all help on this. Thank you.
