Norton Insight
Norton Insight whitelists files based on reputation. Norton-branded antivirus software then leverages the data to skip known files during virus scans. Symantec claims quicker scans and more accurate detection with the use of the technology. Development Insight was codenamed ''Mr. Clean''. Its initial aim was to help users determine what programs from the Internet are safe to install. Mr. Clean would provide a risk assessment to discern between safe and malicious files. However, its goal was later changed to making virus scans more efficient; instead of scanning every file, known files are skipped, cutting scanning times. Basic introduction & usage Norton Community Watch, a voluntary and anonymous service, allows a user's Norton product to forward information to Symantec servers. Among the data collected are the processes running and their SHA256 values. A reappearing hash value and its corresponding file are whitelisted, and Norton Insight checks the processes on a user's comp ...

NTFS
New Technology File System (NTFS) is a proprietary journaling file system developed by Microsoft. Starting with Windows NT 3.1, it is the default file system of the Windows NT family. It superseded File Allocation Table (FAT) as the preferred filesystem on Windows and is supported in Linux and BSD as well. NTFS reading and writing support is provided using a free and open-source kernel implementation known as NTFS3 in Linux and the NTFS-3G driver in BSD. By using the convert command, Windows can convert FAT32/16/12 into NTFS without the need to rewrite all files. NTFS uses several files typically hidden from the user to store metadata about other files stored on the drive which can help improve speed and performance when reading data. Unlike FAT and High Performance File System (HPFS), NTFS supports access control lists (ACLs), filesystem encryption, transparent compression, sparse files and file system journaling. NTFS also supports shadow copy to allow backups of a system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SONAR 2
SONAR is the abbreviation for Symantec Online Network for Advanced Response. Unlike virus signatures, SONAR examines the behavior of applications to decide whether they are malicious. SONAR is built upon technology Symantec acquired in its late 2005 purchase of WholeSecurity, a developer of behavioral anti-malware and anti-phishing software solutions in the United States. How it works An algorithm is used to evaluate hundreds of attributes relating to software running on a computer. Various factors are considered before determining that a program is malicious, such as if the program adds a shortcut on the desktop or creates a ''Windows Add/Remove programs'' entry. Both of those factors would indicate the program is not malware. The main use of SONAR is to enhance detection of zero day threats. Symantec claims SONAR can also prevent attackers from leveraging unpatched software vulnerabilities. Ed Kim, director of product management at Symantec, expressed confidence in SONAR, "We' ...

Norton Internet Security 2009
Norton Internet Security, developed by Symantec Corporation, is a discontinued computer program that provides malware protection and removal during a subscription period. It uses signatures and heuristics to identify viruses. Other features include a personal firewall, email spam filtering, and phishing protection. With the release of the 2015 line in summer 2014, Symantec officially retired Norton Internet Security after 14 years as the chief Norton product. It was superseded by Norton Security, a rechristened adaptation of the Norton 360 security suite. Symantec distributed the product as a download, a boxed CD, and as OEM software. Some retailers distributed it on a flash drive. Norton Internet Security held a 61% market share in the United States retail security suite category in the first half of 2007. History In August 1990, Symantec acquired Peter Norton Computing from Peter Norton. Norton and his company developed various applications for DOS, including an antivi ...

Digital Signature
A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents. A valid digital signature, where the prerequisites are satisfied, gives a recipient very high confidence that the message was created by a known sender ( authenticity), and that the message was not altered in transit ( integrity). Digital signatures are a standard element of most cryptographic protocol suites, and are commonly used for software distribution, financial transactions, contract management software, and in other cases where it is important to detect forgery or tampering. Digital signatures are often used to implement electronic signatures, which includes any electronic data that carries the intent of a signature, but not all electronic signatures use digital signatures.

PC World (magazine)
''PC World'' (stylized as PCWorld) is a global computer magazine published monthly by IDG. Since 2013, it has been an online only publication.

SHA256
SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. They are built using the Merkle–Damgård construction, from a one-way compression function itself built using the Davies–Meyer structure from a specialized block cipher. SHA-2 includes significant changes from its predecessor, SHA-1. The SHA-2 family consists of six hash functions with digests (hash values) that are 224, 256, 384 or 512 bits: SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256. SHA-256 and SHA-512 are novel hash functions computed with eight 32-bit and 64-bit words, respectively. They use different shift amounts and additive constants, but their structures are otherwise virtually identical, differing only in the number of rounds. SHA-224 and SHA-384 are truncated versions of SHA-256 and SHA-512 respectively, computed with different initial values. SHA-512/224 and SHA-512/256 are also trunca ...

ZDNet
ZDNET is a business technology news website owned and operated by Red Ventures. The brand was founded on April 1, 1991, as a general interest technology portal from Ziff Davis and evolved into an enterprise IT-focused online publication. History Beginnings: 1991 to 1995 ZDNET began as a subscription-based digital service called "ZiffNet" that offered computing information to users of CompuServe.

Internet
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a '' network of networks'' that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s to enable resource shari ...
