Please make sure that you have at least one network interface that is currently active and has an IP address and start this application again."

Problem: The Auto Protect feature in Norton will not turn on and will display error message windows on boot.
Solution: As of Norton AntiVirus 11.0.3, the Auto Protect feature will work in Snow Leopard. To update to 11.0.3, run Live Update or download Norton AntiVirus 11.0.3 from https://software.wisc.edu. Note: Version O of the Security Starter CD provided by the TechStore and by the DoIT Help Desk does not contain Norton AntiVirus 11. Version O of the Security Starter CD contains Symantec AntiVirus 10 which is incompatible with Snow Leopard. Snow Leopard users will need to download Norton AntiVirus 11 instead of using the Security Starter CDs.
