Accessing Websites in Vault without permission

I have logins saved in my vault and have just noticed that Norton is accessing these websites without me even going to them on a newly installed computer!

- Fresh install

- Installed Norton Internet Security

- Logged into Vault

- Monitor outbound traffic

ncolow.exe is accessing the sites in my Vault and I haven't gone to them on this computer!

 

Questions:

Can I turn this off?

Is Norton Logging in my sites without my authority?

Is Norton just checking to see if these sites still exist?
