From Reputation Scan, one can learn how common or rare these files are across Norton users, whether those files are trustworthy, and their age. You can use Reputation Scan to perform a Quick Scan, Full System Scan, or Custom Scan.
Scan Files of Interest in processes and loaded programs.
When you run a Reputation Quick Scan, Norton Internet Security considers the Files of Interest in processes and loaded programs. A Reputation Full System Scan considers all such Files of Interest on the system, whereas a Reputation Custom Scan lets you select the drive, file or folder that you want to scan.
Files of Interest include those that Norton Internet Security considers “known good” files relating to running processes, drivers, services, startup items, as well as browser-helper objects and Windows prefetch. They also include executable files that are listed in the Run registry keys and RunOnce registry keys.
