Runtime Error

Getting this error message on my Windows XP Home system about 30 seconds after starting:

 

Runtime Error!

Norton Internet Security\Engine\18.5.0.125\ccSvcHst.exe

This application has requested the runtime to terminate it in an unusual way. Please contact the application's support team for more information.

 

NIS shuts down and can't be restarted without rebooting, which leads to the above error and shutting down, etc.
