Security History 16 "unauthorized access blocked" messages in the past 24 hours, including 12 in the past two hours. I am not complaining that the attempts were blocked. but is this normal for someone in a private single-family home? Also, I see numerous messages like "Protecting your connection to a newly detected network on adapter 'Bluetooth device ..." I am not aware of a Bluetooth device in use in this house. What does this mean?
