smbus file opens when computer starts

Everytime I turn on my computer now a window opens on the screen showing C:\program files\intel. There are two files folders listed: smbus and infinst. I'm just a home user with Windows XP, but I gather this has something to do with the Intel chipset driver. Why is this happening and what does it mean? Is this some mysterious way to tell me that I need to update my chipset driver? If not, why is this opening? If so, what do I do? I've looked up updating drivers on the Intel site and it looks complicated and risky.
