NHS / Norton HotSpot Security - how does it get version updates?

 

I have NHS running fine on a Win7 laptop, seems to be working fine from what I can tell.

 

The installed version is:  1.0.0.13   but I don't see any mechanism to allow me to check for an updated version.

Does that happen automatically or ????

 

Not quite sure if I should be posting here or on the Mobile Security forum, so if I'm in the wrong place please advise!
