How Norton Antivirus Works
Norton has traditional virus detection method like Signature base and Heuristics base detection, with anti-virus, anti-rootkit, anti-malware, anti-spyware etc. Symantec upgrade and releases new and more improved features with its every release. Signature based detection includes searching for knowing structure within executable code, however your computer can be infected with most new virus which signature is not known. In that case heuristics method can be use it can identify new viruses by variation of such code, in files. Malwares are very difficult to detect even for the most new anti-virus software. If you are using Norton Antivirus, you should update its data-base and virus definition every day, so that when you scan your computer, it can detect all possible threats. Some new features like SONAR, it examines the behaviour of applications to decide whether they are malicious. Various things are checked such as if the program create a desktop shortcut or create add/remove programs entry before determining the program is malicious.
Norton insight is a program that comes with the Norton 360. It improves the speed and quality of computer scan. It identifies well known files of client machine and excludes them from constant monitoring and scanning. It only scans unknown and unsecured files. Skipping the already known files helps the scan more impact.
Norton 360 introduced a very effective tool - Norton Power Eraser, it removes threats which standard anti-virus may miss. It cleans up system where malware prevents anti-virus installation. Apart from these, the key technologies of Norton anti-virus software are anti-virus, anti-spyware, anti-rootkit, and pulse-update - provides up-to-the-minute updates that protect against the latest threats without slowing down your computer, firewall software - that can use for mapping and monitoring network.
