Norton Safe Search for Chrome Requires New Permissions?

For the past few days when I launch Chrome on my Windows 7 desktop I get a message saying "The newest version of the extension “Norton Safe Search as default for Chrome” requires more permissions so it has been disabled.

It can now:

and there is a Re-enable button. I haven’t pressed that as this sounds just like something malware would do to get around Safe Search.

The window does have the Norton logo in the upper left but I’m sure that’s easy enough to fake.

Is this a legitimate Norton message? Should I select Re-enable for what sounds like dangerous abilities?

And if not, should I just select the “Remove from Chrome” button or do I need to do more?

Thanks for any light you can shed on this worrisome message.
