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.
