Not sure if I'm posting this question in the right spot or not, but I did a manual scan of my computer today using McAfee. When completed I looked at the log viewer at "inbound events." It said that my computer was pinged and it listed an IP address. I clicked on the trace feature and it came from San Diego. Why would my computer be pinged? What is the purpose of pinging?? And is there is anyway to find out who is pinging me??
