Immunet
Immunet was a free, cloud-based, community-driven antivirus application, using the ClamAV and its own engine. The software is complementary with existing antivirus software. In January 2011 Immunet was acquired by Sourcefire. The application is free-of-charge, although a commercial version is available. It claims to be lightweight and provides always up-to-date protection against the threats. Virus signature files are stored in the cloud, not on individual computers, so signature downloads are not required. Once a virus is detected and blocked for one user, all other Immunet users receive the same protection almost instantly. The software is noted for its ability to allow individual users to easily author their own signatures. Products Immunet was previously provided by Sourcefire in two editions, Free (for personal use), and Plus (for commercial use). As of June 10, 2014, the commercial version was discontinued, though Cisco (having acquired SourceFire) continued to suppor ...

Comparison Of Antivirus Software
Legend The term "on-demand scan" refers to the possibility of performing a manual scan (by the user) on the entire computer/device, while "on-access scan" refers to the ability of a product to automatically scan every file at its creation or subsequent modification. The term " CloudAV" refers to the ability of a product to automatically perform scans on the cloud. The term " Email security" refers to the protection of email from viruses and malware, while " Antispam" refers to the protection from spam, scam and phishing attacks. The term " Web protection" usually includes protection from: infected and malicious URLs, phishing websites, online identity (privacy) protection and online banking protection. Many antivirus products use "third-party antivirus engine". This means that the antivirus engine is made by another producer; however, the malware signature and/or other parts of the product may (or may not) be done from the owner of the product itself.

Antivirus
Antivirus software (abbreviated to AV software), also known as anti-malware, is a computer program used to prevent, detect, and remove malware. Antivirus software was originally developed to detect and remove computer viruses, hence the name. However, with the proliferation of other malware, antivirus software started to protect against other computer threats. Some products also include protection from malicious URLs, Spam (electronic), spam, and phishing. History 1971–1980 period (pre-antivirus days) The first known computer virus appeared in 1971 and was dubbed the "Creeper (program), Creeper virus". This computer virus infected Digital Equipment Corporation's (Digital Equipment Corporation, DEC) PDP-10 mainframe computers running the TENEX (operating system), TENEX operating system.

Windows 7
Windows 7 is a major release of the Windows NT operating system developed by Microsoft. It was Software release life cycle#Release to manufacturing (RTM), released to manufacturing on July 22, 2009, and became generally available on October 22, 2009. It is the successor to Windows Vista, released nearly three years earlier. Windows 7's Windows Server, server counterpart, Windows Server 2008 R2, was released at the same time.

Freemium
Freemium, a portmanteau of the words "free" and "premium", is a pricing strategy by which a basic product or service is provided free of charge, but money (a premium) is charged for additional features, services, or virtual (online) or physical (offline) goods that expand the functionality of the free version of the software. This business model has been used in the software industry since the 1980s. A subset of this model used by the video game industry is called free-to-play. Origin The business model has been in use for software since the 1980s. The term ''freemium'' to describe this model appears to have been created much later, in response to a 2006 blog post by venture capitalist Fred Wilson summarizing the model:Give your service away for free, possibly ad supported but maybe not, acquire a lot of customers very efficiently through word of mouth, referral networks, organic search marketing, etc., then offer premium-priced value-added services or an enhanced version of y ...

Cloud Computing
Cloud computing is "a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand," according to International Organization for Standardization, ISO. Essential characteristics In 2011, the National Institute of Standards and Technology (NIST) identified five "essential characteristics" for cloud systems. Below are the exact definitions according to NIST: * On-demand self-service: "A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider." * Broad network access: "Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations)." * Pooling (resource management), Resource pooling: " The provider' ...

File Signature
{{short description, Data used to identify or verify the content of a file In computing, a file signature is data used to identify or verify the contents of a file. In particular, it may refer to: * File magic number: bytes within a file used to identify the format of the file; generally a short sequence of bytes (most are 2-4 bytes long) placed at the beginning of the file; see list of file signatures * File checksum or more generally the result of a hash function A hash function is any Function (mathematics), function that can be used to map data (computing), data of arbitrary size to fixed-size values, though there are some hash functions that support variable-length output. The values returned by a ... over the file contents: data used to verify the integrity of the file contents, generally against transmission errors or malicious attacks. The signature can be included at the end of the file or in a separate file. External links List of file signaturesPublic Database ...
