Norton WiFi Privacy General Questions

I am thinking of ordering the Norton WiFi Privacy. 1)Will this be effective if I generally use a 3G connection? I do not have WiFi in my home (yet). 2)If the apps come up before the VPN loads, is all of my data still secure? If not, what would I do in a situation like this? Thank you.

Thank you for your response. You gave detail, and I appreciate it.

1.  Yes, it will cover Wifi, Ethernet, or any other internet connection. 

2.  What apps are you concerned about? Most apps that access the internet will not start until you manually start them. The main differences might be the OS, and your Security product that might look for updates. But they should be secure enough on their own. The VPN should get loaded before you start up your email or browser.
