Do you mean Norton Internet Security? The latest version (5.3) is not compatible, but an earlier version (4.1) is included on the CD (or dmg download) for 10.4 through 10.6 users.

Sorry, I need to clarify. The version of NIS included in Norton 360 Everywhere is NIS 5, which does not support Snow Leopard. At least I don't believe the older version, NIS 4, is included (as when NIS is purchased separately). If someone else knows differently, please feel free to correct me.
