About Intrusion Prevention exclusion list
The Intrusion Prevention System in Norton Internet
Security scans all the network traffic that enters and
exits your computer. When a device on your network
requests access to your computer, Intrusion Prevention
scans this request to ensure that it is not a virus attack.
If the information matches an attack signature,
Intrusion Prevention blocks the traffic from the
suspicious device and protects your computer.

down the network speed of your computer.
If you are sure that a device on your network is safe,
you can change the trust level of the device to Full
Trust. You can configure the trust level of a device
