I'd like to know why I'm at risk before I tell Norton to fix it.

So with the new update Norton helpfully tells me I have a security risk or performance issue or whatever, and gives me the option to "fix now". But it doesn't say what's wrong or what it is going to do anywhere that I can find. If I need an update or a disk optimized that's fine. But if it was going to repair firewall settings or make some sort of change to how my computer is configured, I would like to know before I tell it to go ahead.
