Yeah, 4.3 broke a lot of tethering apps that so far haven't been fixed.

Make sure your phone is protected by updating the security policy to the latest version from Samsung.

I didn't allow it to update or do anything and after another reboot I haven't seen it or any other similar message again. Here's to hoping it stays gone.
This has been an issue that people on the international version have had as well, and it seems to stem from apps not being updated to handle the Knox security suite without coming up as a false positive. Best bet is to figure out which app it is and e-mail the developer so they can work on a fix.
