Monitoring your networks
If you have McAfee Total Protection installed, Network Manager also monitors your networks for intruders. Each time an unknown computer or device connects to your network, you'll be notified about it so you can decide whether that computer or device is a Friend or an Intruder. A Friend is a computer or device that you recognize and trust, and an Intruder is a computer or device that you don't recognize or trust. If you mark a computer or device as a Friend, you can decide whether you want to be notified each time that Friend connects to the network. If you mark a computer or device as an Intruder, we'll automatically alert you each time it connects.
The first time you connect to a network after installing or upgrading to this version of Total Protection, we'll automatically mark each computer or device as a Friend and we won't notify you when they connect to the network in the future. After three days, we'll start notifying you about each unknown computer or device that connects so that you can mark them yourself.
