"no Identity Rule Added" - What Is It And How Do I "fix" It?

I just installed BitDefender Antivirus 2008. It gives me a screen that shows a yellow button for Identity Rules. I searched through the Help menus, but there is no description of what an identity rule is or what I type in to fix the yellow button problem.

Can someone explain this so I can make a "rule" - whatever "rule" is. A rule for what activity?? It seems this is a pretty basic question - Sorry . . . Thanks for your help.
