If you are sure that a device on your network is safe,
you can change the trust level of the device to Full
Trust. These trusted devices can be excluded from
Intrusion Prevention scan.
Intrusion Prevention relies on an extensive list of
attack signatures to detect and block suspicious
network activity. Norton Internet Security runs
LiveUpdate automatically to keep your list of attack
signatures up to date. If you do not use Automatic
LiveUpdate, you should run LiveUpdate once a week.
