Is Norton blocking itself?

I've only recently installed Norton Internet Security for Mac.  I'm regularly getting a blocked message, in the form of:

 

/private/tmp/symtmp.NbAPU5/action.sh

where the NbAPU5 part of the string is always a different set of characters.

 

This is listed in history as an outgoing communication.

 

Looking this up in other unanswered or off-topic threads, there's speciulation that this is SYMtmp for Symantec.

 

Two questions:

 

- Is there something wrong with the install that this keeps blocking outgoing communication

- Can these be made to go away?  Because the "NbAPU5" ish part of the string always changes it seems this can never be permanently added to be ignored.

 

Thanks,

-Ric
