Internet Security performs the Insight Network scan,
it uses the virus definitions that are available locally
and in the Cloud. Norton Internet Security provides
additional protection by using the most recent
definitions in the Cloud, apart from the definitions that
are available locally on your computer.
Norton Internet Security performs an Insight Network
scan only when the Insight Protection option is turned
on. To turn on the Insight Protection option, go to the
Norton Internet Security main window, and then click
Settings > General > Other Settings > Insight
Protection > On. By default, the Insight Protection
option is turned on.
When the Insight Protection option is turned on,
Norton Internet Security performs a traditional scan
and an Insight Network scan simultaneously. The
traditional scan uses the definitions from the local
system, and the Insight Network scan uses the
definitions that are hosted in the Cloud.
Threat detection based on the Cloud definitions is
identical to the threat detection that is based on the
local definitions. However, the Cloud definitions are
specified with additional data about the threats that it
detects which indicates that it has been obtained from
the Internet. Definitions in the Cloud provide a generic
name for the risk detected, but the local definitions
provide the specific name for the risk detected. For
example, if a Trojan horse is detected, the scan results
of the Insight Network might display Cloud.Trojan.
However, the scan results of the local definition might
display Trojan.Foo.
If the traditional scan completes while the Insight
Network scan is still running, you can view the Insight
Network Scan progress status.
If the Insight Protection option is turned on, you can
manually run the following types of Insight Network
scans:
