Anti-virus program can be dangerous for the following reasons:

Some anti-virus program is only a simple technology that can easily be deceived manufacturers, such as virus, anti-virus program checks only a few bytes of the beginning of the virus, the virus may make another version of the virus early part of the same, but different in other important areas, such as the conventional encryption / decryption the original file header. This will enable the anti-virus program file destroyer, rather than save the file. Some anti-virus can also be cheating to change the virus signature file. Signature file is a file that contains the identity of all known viruses of the antivirus software, antivirus software, if the ID in turn, do not know. A good anti-virus software should be able to check the file signature has been changed.
Anti-virus software can not create a backup file is cleared. Typically, anti-virus program (especially specific) do not provide the means to create a clean backup file, which is very important to the cleaning process failed.
Anti-virus software can not be self-examination. Self-examination is necessary, anti-virus program can modify the others to arrive before the hands of users. Anti-virus program is commonly used self-censorship, commerce, and to ensure that he does not modify any person, but some are not, it is harmful. At the local anti-virus programs, usually including a number of articles on the computer, usually including source code, you should compile your own source code, if you suspect the authenticity of his exe file.
Anti-virus program can turn off the resident’s place of residence should not be the best anti-virus detection and unloading easy. Examples of anti-virus software poor people VSAFE (in the DOS package). VSAFE can be detected and disabled to use interrupt (you try to learn / debug vsafe in the DOS program, so that you understand). Users will get a false sense of security, the use of the virus. No sense of security is better than false sense of security.
Anti-virus software can not be given a warning expired. As time goes by, the virus which appears more and more advanced technologies. A good anti-virus program should be given a warning, if you use Antivirus’m outdated. This is important, so that the virus incidents will not happen again spread of the virus.

Product key card is a license card package, a key office in 2010, allows the user to enable or unlock the office 2010. Microsoft does not have a product key in Office 2010 is the DVD format, so the environment is friendly, small-scale than the DVD package. Office 2010 beta version has been published in November last year, has been downloaded more than 200 million people around the world, according to Microsoft. Microsoft is also setting up a test version will expire in October 2010, while waiting for the final version of Office 2010 in June 2010.

Further information on the activities not mentioned in the above-mentioned preparatory work other than Microsoft operating systems will be updated every two years, which means that Windows 8 will soon be. Microsoft has not yet explained in detail in order to develop Windows 8, including the logo will engage experts to help build the system.

Windows Mobile 6.5 may be just showing off, but Microsoft is preparing to replace. The Windows Mobile 7, a new system will be entered into the phone, supported by social networking sites. Mobile operating system is expected to attend next year, about a year later, the popular Windows Mobile 6.5. According to us.rd.yahoo.com, Microsofy’s 1.000 employees are developing the operating system Windows Mobile 7.

“Social networking and mobile phones, two phenomena, developed rapidly, culture, social culture, where they gave a great influence to the interaction between users. To this end, a group of Windows Mobile 7 communication is under construction telephone system, which can represent a friend, pictures, news and events into one. Our goal is to achieve social integration into its mobile phone network. For example, imagine if all of the news feeds of all the social networks a mobile phone. ”Microsoft’s.

In essence, Microsoft hopes to establish a mobile social platform, which will enable developers to create social applications of the system Windows Mobile 7. ”The version of Windows Mobile 7 is designed for true mobile phone personalization and relevance, or what we call ‘epic phone’, immediately went into the mobile phone market.” Added Microsoft.

Linux has long been know to use server, and get companies such as Dell’s leading computer, Hewlett-Packard, IBM Corporation, Novell, Oracle, Red Hat Inc. and Sun Microsystems. Linux as an operating system, different types of computer hardware, including desktop computers, supercomputers and embedded systems, such as e-book reader, video game systems (the PlayStation 2, PlayStation 3 and Xbox), mobile phones and routers. Analysts believe that the success of information technology, Linux, because Linux is not dependent on suppliers (suppliers of independence), low operating costs and increase the compatibility than the paid versions of UNIX, as well as the safety factor and the high sex ratio of other operating systems , such as Microsoft Windows. These features also can be used as evidence in the interests of the development model, open source software (open source software).

Linux operating system, known as the Linux distribution version of Linux (Linux distribution) typically includes device support software, such as Web servers, programming languages, databases, desktop monitors (desktop environment) (such as Gnome and KDE), office applications package (office suite ) If OpenOffice.org, the KOffice, Abiword, and those gnumeric’s.

Most of the code (71%) is to use C programming language, but are also involved in many other languages such as C + +, assembly language, Perl, Python, and Fortran languages, and various other scripting languages. More than half of all the code under the GPL license. Linux kernel itself consists of 2.4 million lines of code, or about 8% of the total. [37]

Other studies have a similar analysis, the distribution of Debian GNU / Linux 4.0 version.Distribution, including more than 283 million lines of code, and study for the development of estimated cost of 5.4 billion euros, if developed into a closed software.

In the United States, Linux is a trademark (No.: 1.91623 million) is owned by Linus Torvalds.Linux, registered as a “computer operating system, the use of computer programs and actions.”This is a trade mark registration, place a forger named William • De La Cross began to send letters to its small Linux and the Linux distributors are entitled to expect their property, and asked to pay certain royalties 10%, where. Linux distributors began promoting the mark to Linus Torvalds, the original. Linux trademark license under the supervision of, the current Linux Mark Institute.

There are many Linux distributions (often referred to as distribution) by individuals, groups or other agencies. Each program includes systems and other applications, in addition to including a program, the entire system is installed on your computer (install program).

The core of each issue is a Linux kernel, a collection from the GNU project (or other items), Shell (shell), and utility management, such as libraries (library), compiler and editor (editor).Most systems also include non-utilitarian GNU-regulation. However, these tools can be separated and Unix-style systems are still available. Some examples are practical BSD and graphics system – X (Under X – Window system). X provides a graphical user interface (GUI) is a common Linux operating system.
