Netgear Armor unauthorized access to network

Greetings,

Two months ago, I installed the Nighthawk RS300 router, and declined the Netgear Security/Protection Engine service, although it has enabled itself without my consent.

I am unable to disable this entirely.

Now I have noticed that my HP printer is printing 5 pages of garbage at random times of day or night. This is not in response to any command or job I have sent to the printer.

The printer gibberish has been identified as "ONVIF" commands and "rtsp://" requests. These are typically probes for an IP security camera or Internet of Things type devices with streaming video.

However, the requests go to an unassigned tcp port, tcp/9999, and since the HP printer is listening there, triggers the gibberish printout (5 pages long) every time the network is scanned.

It appears that Netgear Armor and/or "Protection Engine" is doing unauthorized and opaque scanning of my LAN and triggering these printouts. These printouts cost money, for paper, toner, wear and tear on the printer hardware. Go to any library, or print shop, and see how much they charge a customer for 5 pages to print out there. These network scans are not benign but they indicate malware on my network, and they need to be blocked and disabled at the source.
