I'm getting dozens of notifications of sites being blocked when no one is using our computer. They are always from these IP addresses: http://50.18.186.167/arm.asp and http://46.137.164.186/arm.asp. I got oaver 30 last night when everyone was asleep and I get then throughout the day, but mostly at night. The computer was on, but the browser (neither Firefox for IE) were open. Anyone know about these IP addresses or why NOF is blocking things when the computer and browser aren't being used?
