ARP Cache Poision alerts
Brought home a new laptop today, and as soon as I connected it to my wifi I immediately began getting inundated with Norton alerts saying, "Vulnerability blocked." These alerts were coming at the rate of two or three every five seconds or so (the alerts were defined as ARP Cache Poison alerts). After reading about this alert in a closed thread on this forum, and searching the Internet, I finally realized the problem. I have the Disney Circle device set up in my home, and I had forgotten to register the new computer to it. Generally I only realize the circle is blocking a device when someone is having trouble connecting to the Internet, so this behavior was new. But it was the same problem. Hopefully I am saving someone out there a big headache if you are encountering the same thing.
