Making sure I have newest versions for NIS 2011

NIS 2011 v18.7.0.13
Vista OS w/Vista SP2
IE 8 browser

If I understand correctly, the newest versions for NIS2011 v 18.7.0.13
Norton Tool Bar is
2011.7.6.3

Norton Vulnerability Protection
10.1.0.68-2

1. Are those the newest versions for NIS 2011?

2. is Norton Vulnerability protection the same as intrusion protection?

3. Where in the Vista OS can I check to see that I have the updated tool bar and Vulnerability Protecion versions? What are the paths to those files?
