By any chance, do you clear your cookies and history before you tuck your PC in for the night? If not then I suspect that it is a cookie that is waking up and sending in its report for the day.
I suggest that you use CCleaner and MRU_Blaster before you shut it down.

No- I used to run cookie wall by analogueX which was great at preventing cookies from remaining on computer, and an easy place to see them all and delete new ones etc- I should reinstall that-
