Recent versions of Norton AntiVirus (v4.0 and later) incorporate Symantec's advanced Bloodhound technology to detect new and unknown viruses; currently the client detects more than 46,000 known viruses as well as many more unknown viruses via the Bloodhound technology.
Bloodhound scrutinizes the overall structure, logic, data, and other attributes of a program and then uses heuristic logic to assess the likelihood of viral infection. This allows NAV to provide some of the best virus protection available, automatically detecting and disinfecting up to 95% of all new and unknown viruses.
