WinPatrol declared a Trojan

I have had NIS 2009 installed since they finally fixed the bug that prevented Windows file sharing.  I have had WinPatrol V8 installed even longer.  They never seemed to interact.  Suddenly last week NIS is constantly calling WinPatrol a Trojan program.  Even if I tell it to ignore, it comes back with the message on next scan.  Anyone have any idea why this action is suddenly happening - and how to resolve it?

 

Thanks
