The last time I checked you could just plug in your external address and it would work. Did not know they ever changed it.
I really have no idea, I could be wrong on this one anyways.
Using the 35TVW8JXxnrPviwyZoRbtNfs2RD1vXNRu1 address the OP posted when you google it there is no discussion about it.
You should probably add more keywords such as virus/infected/hack, and you should be able to find posts such as this one
Good evening fellow miners! Just wanted to let you know that I’ve had another S9 hacked today and the controller is ruined and I ran out of the replacement controllers

Firewall is set to medium, if I set it to higher level then the miners don’t connect. Not sure what else I can do to stop this guy from stealing my coins and braking my hardware.
If anyone is interested here is the address that this bastard puts instead of my pool settings and his wallet address.

The controllers can not be hard reset, the address can not be changed. BEWARE AND KEEP YOU NETWORK SAFE¡
Good night and mine on! The block is coming soon!

This quote brings some bad news to OP, some virus's versions lock you out of your control board, and this seems to be one of them, let's hope he gets lucky.
