SeaMonkey

SeaMonkey is a free and open source cross-platform Internet suite. It is the continuation of the former Mozilla Application Suite, based on the same source code. Core Mozilla project source code is licensed under a disjunctive tri-license that gives the choice of one of the three following sets of licensing terms: Mozilla Public License, version 1.1 or later, GNU General Public License, version 2.0 or later, GNU Lesser General Public License, version 2.1 or later.
SeaMonkey consists of a web browser (SeaMonkey Navigator), which is a descendant of the Netscape family, an e-mail and news client program (SeaMonkey Mail & Newsgroups, which shares code with Mozilla Thunderbird), an HTML editor (SeaMonkey Composer) and an IRC client (ChatZilla). The development of SeaMonkey is community-driven, in contrast to the Mozilla Application Suite, which until its last released version was governed by the Mozilla Foundation. The new project-leading group is the SeaMonkey Council.

Norton AntiVirus

Norton AntiVirus, developed and distributed by Symantec Corporation, provides malware prevention and removal during a subscription period. It uses signatures and heuristics to identify viruses. Other features include e-mail spam filtering and phishing protection.
Symantec distributes the product as a download, a box copy, and as OEM software. Norton AntiVirus and Norton Internet Security, a related product, held a 61% antivirus market share as of 2007. Competitors, in terms of market share, include antivirus products from CA, Trend Micro, and Kaspersky Lab.
Norton AntiVirus runs on Microsoft Windows and Mac OS X. Version 17.0.0.136 is the latest Windows build. Windows 7 support is in development for versions 2006 through 2009. Version 2010 will natively support Windows 7, without needing an update. Version 11.0.3 is the latest Mac build.

In August 1990 Symantec acquired Peter Norton Computing from Peter Norton. Norton and his company developed various utilities, or applications for DOS, including an antivirus. Symantec continued the development of acquired technologies. The technologies are marketed under the name of "Norton", with the tagline "from Symantec". Norton's crossed-arm pose, a registered U.S. trademark, was traditionally featured on Norton product packaging. However, his pose was later moved to the spine of the packaging, and eventually dropped altogether.
Product activation was introduced in Norton AntiVirus 2004, addressing the estimated million counterfeit Norton products sold. A alphanumeric code is generated to identify a computer's configuration, which ties in with the product key. Users are allowed to activate their product five times with the same product key. Spyware and adware detection and removal was introduced to the 2005 version, with the tagline "Antispyware Edition". The tagline was dropped in later releases. However, Norton AntiVirus 2009 Classic does not include spyware or adware detection. The Classic edition is marketed alongside Norton AntiVirus 2009, which does include spyware and adware detection.
Existing users of the 2006, 2007,2008 and 2009 versions can upgrade to the latest 2010 version without buying a new subscription. Upgrading will preserve the number of days left on a user's

The Business Edition packages add ESET Remote Administrator allowing for server deployment and management, mirroring of threat signature database updates and the ability to install on Microsoft Windows Server operating systems.

Initially the program gained popularity with IT workers in Eastern European countries, as ESET was based in Slovakia. Though the program's abbreviation was originally pronounced as individual letters, recent worldwide use of the program has led to the more common single-word pronunciation, sounding like the English word nod.The company reached its 4000th update to virus definitions on April 10, 2009.

WinZip

WinZip is a proprietary file archiver and compressor for Microsoft Windows, developed by WinZip Computing (formerly Nico Mak Computing). It natively uses the PKZIP format but also has various levels of support for other archive formats.
WinZip was created in the early 1990s as a shareware GUI front-end for PKZIP. Sometime around 1996 the creators of WinZip incorporated compression code from the Info-ZIP project, thus eliminating the need for the PKZIP executable to be present.
From version 6.0 until version 9.0, registered users could download the newest versions of the software, enter their original registration information or install over the top of their existing registered version, and thereby obtain a free upgrade. As of version 10.0 this upgrade scheme was discontinued. WinZip is available in standard and professional versions. However, the ability of Windows XP and later versions of Microsoft Windows to open and create .zip files (as "compressed folders") has reduced the need for extra compression software.
In May 2006, Corel Corporation, known for its WordPerfect and CorelDRAW product lines, announced that it has completed acquisition of WinZip Computing.
WinZip has a 45-day free evaluation period, after which the program would still work even if the user had not registered, albeit with reduced functionality. However in later versions this feature appears to have been removed, although users are able to bypass this by downloading an earlier version.

Windows Vista

Windows Vista is a line of operating systems developed by Microsoft for use on personal computers, including home and business desktops, laptops, tablet PCs, and media center PCs. Prior to its announcement on July 22, 2005, Windows Vista was known by its codename "Longhorn." Development was completed on November 8, 2006; over the following three months it was released in stages to computer hardware and software manufacturers, business customers, and retail channels. On January 30, 2007, it was released worldwide, and was made available for purchase and download from Microsoft's website. The release of Windows Vista came more than five years after the introduction of its predecessor, Windows XP, the longest time span between successive releases of Microsoft Windows desktop operating systems. It was succeeded by Windows 7 which was released to manufacturing on July 22, 2009, and for the general public on October 22, 2009.
Windows Vista contains many changes and new features, including an updated graphical user interface and visual style dubbed Windows Aero, a redesigned search function, multimedia tools including Windows DVD Maker, and redesigned networking, audio, print, and display sub-systems. Vista aims to increase the level of communication between machines on a home network, using peer-to-peer technology to simplify sharing files and digital media between computers and devices. Windows Vista includes version 3.0 of the .NET Framework, allowing software developers to write applications without traditional Windows APIs.
Microsoft's primary stated objective with Windows Vista has been to improve the state of security in the Windows operating system. One common criticism of Windows XP and its predecessors is their commonly exploited security vulnerabilities and overall susceptibility to malware, viruses and buffer overflows. In light of this, Microsoft chairman Bill Gates announced in early 2002 a company-wide "Trustworthy Computing initiative" which aims to incorporate security work into every aspect of software development at the company. Microsoft stated that it prioritized improving the security of Windows XP and Windows Server 2003 above finishing Windows Vista, thus delaying its completion.
While these new features and security improvements have garnered positive reviews, Vista has also been the target of much criticism and negative press. Criticism of Windows Vista has targeted its high system requirements, its more restrictive licensing terms, the inclusion of a number of new digital rights management technologies aimed at restricting the copying of protected digital media, lack of compatibility with some pre-Vista hardware and software, and the number of authorization prompts for User Account Control. As a result of these and other issues, Windows Vista had seen initial adoption and satisfaction rates lower than Windows XP. However, with an estimated 330 million internet users as of January 2009, it had been announced that Vista usage had surpassed Microsoft’s pre-launch two-year-out expectations of achieving 200 million users. At the release of Windows 7 (October 2009), Windows Vista (with approximately 400 million internet users) was the second most widely used operating system on the internet with an approx. 23.6% market share, the most widely used being Windows XP with an approx. 60% market share.
