Norton Security (software installed on the computer) supposedly blocked a fake website coming from my internet router.
(See the full alert details window screenshot).
My internet router is a BT Home Hub 5 and the IP address http://192.168.1.254 is the router's IP address and UDP port 53 seems to be the DNS. All other devices (computers, smartphones, tablets etc.) connected to the network are assigned different IP addresses.
Is there something in the router which may be attempting to compromise security?
