Norton AntiVirus (NAV) has the ability to detect unknown viruses of various types using heuristic algorithms known as Bloodhound. This technology was developed by Symantec Security Response.
If NAV detects a Bloodhound virus, Symantec Security Response recommends the file be submitted for further analysis. For instructions on how to do this, see the document How to submit a file to Symantec Security Response using Scan and Deliver.
