Norton AntiVirus 11.1 for Mac, Live Update Messages ask for 2 Symantec Keys every time

NAV 11.1 for Mac  is working fine so far, but I am getting those 2 messages, after starting LIVE Update:

 

1. Norton Antivirus wants to use the "Symantec" key

 

2. IR Tool wants to use the "Symantec key"

 

What do I have to type In as "Symantec key" ?

 

Please let me know, what to do to get rid of those 2 messages, which appear every time I run LIVE UPDATE, thank you.
