Symantec Software (Beijing) Co., Ltd., Norton, started in the United States in 1982, the world's top ten antivirus software, widely used anti-virus programs, including Norton Internet Security SWAT/Norton Anti-Virus/Norton 360/Norton Computer Master and other products

Norton Antivirus is one of Symantec's personal information security products and is a widely used anti-virus program. Since the development of this product, in addition to the original anti-virus, it also has the function of anti-espionage and other network security risks.

Norton Anti-Virus products include: Norton Internet Security, Norton Antivirus, Norton 360 (Norton ALL-IN-ONE Security), Norton Computer Master, SystemWorks, and other products. Symantec also has an enterprise-specific version called Symantec Endpoint Protection.

firewall

The firewall of the NIS is a two-way firewall and hides the computer from the network.

BloodHound heuristics

The easiest and most effective way to identify whether a suspicious program is threatening or not is a heuristic is the easiest and most effective way to induce malicious programs to appear without affecting the actual machine. BloodHound is Symantec's exclusive heuristic detection technology that detects viruses through suspicious behavior. BloodHound creates a virtual security environment where the virus can manifest its bad intentions without affecting the stability of its own computer.

SONAR (Symantec Advanced Online Networking Technology)

Enlightenment only runs on the virtual host, and if the virus Trojan unfortunately enters the physical host, it will have to use the "behavioral defense technology"; Behavioral Defense analyzes the behavior of suspicious programs and blocks them before they occur, and Norton's famous SONAR is undoubtedly the most sophisticated of them all. The general behavioral defense is very passive and only works when the malicious program is connected to the outside world; Norton, on the other hand, takes a "proactive" approach, scanning every file read or write immediately (in real time), greatly reducing the risk of being hacked.

Browser protection

As the name suggests, vulnerability protection is a defense method that prevents and blocks system vulnerabilities and allows threats to invade "without even a door". Managing vulnerabilities directly is obviously much more efficient than a large number of virus patterns. Norton's approach is to keep a close eye on the most frequently hacked browser vulnerabilities, so that whether you're an IE or Firefox user, you'll get the most complete protection. In 2009, even the multimedia plug-in vulnerability was effectively controlled.

Identity Protection

The ultimate purpose of network security software is to protect the computer itself and the files and data stored in the computer. Online account passwords are the most important but also the most easily stolen, and once leaked, they often cause significant financial losses. Norton's exclusive card-based identity protection provides the best way to respond, and users are automatically logged in through the card every time they go online, so that users are not intrusive by malicious programs such as keyboard recording.

Norton Insight智能型扫描

Norton Insight, a new technology added to Norton Antivirus in 2009, is simply a whitelist (but the list rules are not stored in the software, but are updated at any time through Symantec's other platforms), which only scans untrusted files or websites, and skips well-known or safe files and websites, which can greatly speed up the scanning speed and reduce the false positive rate.
