JOHN!!!
WHAT!!!
I have no idea what Norton would see as phishing. The Google Ads on the side and the weather report on the bottom are both off-site links and it's possible those are triggering it. But that's new, since I haven't changed the content or layout in weeks.
I'll poke around and try to figure it out. In the meantime, if anyone seeing this can provoke this and provide me with deeper information, it would be helpful. Do not respond to this message; send such information to me as a PM.
