About Norton Insight

Norton Insight allows the smart scanning of files on

your computer. It improves the performance of Norton

AntiVirus scans by letting you scan fewer files without

compromising the security of your computer.

A Norton AntiVirus scan can identify threats on your

computer in the following ways:

At regular intervals, Norton

AntiVirus obtains definition

updates from Symantec. These

updates contain signatures of

known threats. Each time when

Norton AntiVirus obtains the

definition updates, it performs

a scan of all of the files that are

available on your computer. It

compares the signature of the

files against the known threat

signatures to identify threats on

your computer.
