I turned on my laptop late this afternoon after shutting it down last night and had this pop-up window from my security software. "Network Threat Protection 10-1-2011 5:54:28pm. Here's the message "NT Kernel System has changed since the last time you used it. This could happen if you have updated it recently. Click Detail to see more iformation. Do you want to allow it to access the network?" I don't think I updated anything and not sure what to do. I am running Windows 7 (32-bit). How should I proceed on this? I have never seen this message before.
