Computer virus have been released first time in January 1986. This virus attach to the boot sector of storage media formated with the DOS file allocation table or FAT file system. This virus can make a program that shows other location of boot sector on a floppy disk with a copy of virus. The boot sector then marked as a bad infected disks usually have five kilobytes of a bad sectors.
At that time the virus programmer is want to be famous like music or film stars, they are not conceal their identity. Every time the virus infected to the computer or disk, they will give a message that show their identity even their address or phone number.
For example the message of computer that infected by a virus came complete with the brothers' address and three phone numbers, and a message that told the user that their machine was infected and to call them for inoculation.

Computer Viruses and Computer Worm
There are two kind of microbe for computer, soft microbe and hard microbe. Soft microbe mean microbe made by human this is a software able to make program damage, but hard microbe is a dirt that can make damage of all your computer parts.
Computer Viruses
A virus is a self-replicating program that spreads by inserting copies of itself into programs or documents that already exist on a computer. The name comes from an analogy with biological viruses. These cannot reproduce by themselves but make use of the functions of infected cells to spread. Similarly, a computer virus makes use of the executable code in legitimate programs to carry out its purposes. A virus may be designed to be destructive to a system or to be a prank. In either case, the virus will rapidly reproduce itself until the system may be overwhelmed. Viruses spread to other systems when infected programs are copied to another machine. Documents with executable code like Word macros can also be vectors of infection. A very common method of spreading viruses is by attachments to email . Today a variant of a virus known as a worm is more often used.
Computer Worms
Viruses and worms are often lumped together in the single category of virus but there is technical distinction. A worm differs from a virus in that it contains all the code it needs to carry out its purposes and does not depend on using other programs. Most recent instances of malware have been worms, spread primarily by email. Worms are designed to replicate rapidly and to use the Internet or other networks to spread with great facility. They may contain code to damage or erase files or may carry other malicious payloads. On a number of occasions, large numbers of computer systems have been brought down by worms. In addition to the damage from whatever payload they carry, the sheer number of worm copies can bring systems to a halt.
A very common method of spreading is by use of any email addresses on an infected computer. The worm searches address books, temporary Internet caches and other possible sources of email addresses. The worm then mails out random infected fake messages. It may use the addresses it finds not only as recipients but also may spoof mail to show them as senders. It may also combine random pieces of addresses into new fake addresses. All the messages will contain an attachment that is infected. None of this activity may be known by the owner of the infected machine and may go on for weeks or months. A single infected machine can send out thousands of worm-carrying messages.

The team performed a ported version of the IOS and conduct extensive investigations to Objective-C code base. From IOS version there are 15 thousand lines of code for the physical, animation, and drawing machine.

Software war will begin this year, and they also will work together with other hardware company to produce a product that not need to install software and always upgrade that sometime make bored and unpracticed, all computer producer will release new product that always include software inside but with cheap price, so the company that just sold software will difficult to get customers.
New computer design will design and they are different with the old one and don’t need software to upgrade and they are integrated with telephone and electronic equipment that don’t need software and with competitive price. What this kind product we’ll see on the future.
