OperaTor TROJAN? or what? it's downloading something in the background

when I open Operator, my idle internet connection starts recieveing data in what appears to be a download in the background. The data keeps downloading until I shut Operator down or disconnect. I have the home page set to a html on my hard drive. and I dont attempt to open any web pages/downloads or ‘surf’ data just automatically without me asking for it starts downloading to my machine whenever operator starts up. I have been using Operator for quite a while and Im 99.9% certian this is a new behavior and no hidden data was being recieved in the background when operator was open. Is this a TROJAN? it's definately downloading something in the background…
