Complete Guide for Download, Install & Activation

Norton by Symantec is one of the most popular brands in PC security. The Norton's AntiVirus is the core security software that offers necessary protection against viruses and spyware for home and business users. It updates on its own every 5 to 15 minutes and involves an inventive scanner that efficiently checks a PC for threats in very little time.

Norton Security is created essentially to protect home and business users from malware and other threats. Norton’s Protection System stars various levels of malware defense, along with web browser protection for Mozilla Firefox and Internet Explorer, an Intrusion Prevention Tool, Antibot protection to block the malicious conquest, and a system recovery feature for invalidating any harm from infections that do slide through Norton’s protection.

What is Norton AntiVirus?

We are all aware of cyber threats such as viruses and malware, Norton antivirus is a software which is created to fight it off. Norton AntiVirus is a type of program which the user knowingly downloads on their system with the aim to protect their device from virus infiltration and infection. Norton AntiVirus achieves this object in three ways. Firstly, it detects viruses on the PC. Secondly, it removes it from the device safely. Thirdly and lastly, it clears up any damage to the system that the virus may have caused.

Apart from that, Norton security programs block dangerous websites and offer real-time protection. In layman terms, it means that Norton AntiVirus blocks sites and pages which were made with the intention of delivering viruses and the websites which may have been infected with a virus. Norton antivirus keeps running in the backdrop of the system so that even if a piece of virus attempts to infect the computer, Norton Antivirus steps in and protects the computer.

How does Norton AntiVirus do its work?


Several applications look for virus using a database of recognized virus definitions (also known as signatures). These signatures reveal what the virus does and how to identify it. If Norton security software discovers a file that matches the virus signature, it will flag it as a possible virus. This is an excellent way to eliminate known menaces, but it does need periodic updates to make sure the Norton security software does not miss out on recently created viruses.


Another method with which Norton antivirus detects malicious files is a kind of analysis named as heuristics. An option to database scan, heuristic analysis lets Norton antivirus program to identify perils that were not previously known. Heuristics recognizes viruses by behaviors and characteristics, rather than matching against a list of known malware.

For instance, if an app is coded to eliminate essential system data, the Norton antivirus program may flag it as a virus (because apps should not be doing this behavior). However, the heuristic analysis may at times result in “false positives,” or applications flagged as malicious that is valid in reality.


Another method which Norton Antivirus software can detect viruses is by running an application it speculates to be harmful in a sandbox, which is a safe space on the PC. The app thinks it has complete access to the PC when, in reality, it is running in a confined space while the Norton AntiVirus observes its behavior.
