ARP Cache Poison

I'm receiving ARP Cache Poisoning Incoming messages on my MAC.  I've read the posts on Community (although I can't figure out how to reply to anything).

I don't believe this threat is blocked, as my Norton anti-virus software says it can't repair the problem.

What's my best course of action?

Re: ARP Cache Poison

You don't need to do anything to block this threat. This threat is blocked by the Vulnerability Protection component of Norton AntiVirus, and as soon as it's detected it's blocked. You don't need to do anything else to protect your Mac.

Re: ARP Cache Poison

Per other threads, this is frequently due to inappropriate but harmless messages from devices on the network. I'm getting lots from the Linksys WET610N on my network. Is there some way to mark this device as "safe" so I can leave the vulnerability protection enabled generally except for trusted devices? Also, it is misleading to display MAC addresses under a label that says IP address.
