Virus On PC

Some computer virus are ignorant of computer operators or even users, they may often destroy pieces of the computer operating systems that were healthy. Not like when the first independent software’s had no real purpose like they have today. The first virus programs were just done for fun, it’s a battle between the big three dates Bell, Core, and War which were founded in 1970 in the laboratories of ‘the’ company. In this game, all players write a (virus) program and then loaded them into the RAM, (Random Operating System.) The operating system is multitasking, which, in being so, carries an explanation for each program. The goal was to destroy your opponents programs while gaining their own weapons.

The software is able to copy, repair itself, to move in different areas of memory, and the “attacks” on the software occur by introducing a random opponent in other areas of the memory. The game can finish at a certain time or just after a point in time or when a player sees all of their programs have stopped working or killed. The winner is the person who copies the most active programs. This is precisely the principles of the virus program.

Some time during 1984 the popular magazine known as ‘Scientific American’ displayed to their readers a computer game design, which consists of small programs’ auto reproducible in battle and try to harm the opponent, and thus laid down the foundation for future viruses to come into being. In 1986 ARPANET was infected by a virus from the brains of the name of a Disk Operating System (C) Brain. The creators of this virus were quick to leave their name, address and telephone number, because it’s pure advertising for them.

The virus is a classic piece of software, often written in assembler computer language, which is part of the standard program, usually at the end but can also be in the beginning or middle. Every time the user launches the “infected” piece of software, in order to activate the virus, an opportunity arises to integrate into other executable programs on the infected computer. And if it contains a payload, it may take some time (which can be very long) or triggered on a special event, perform predefined, destructive or just silly actions. Often ranging from some simplistic random message being quite harmless to the impairment of vital functions of the operating system or even damage to the files or worse the complete destruction of all data on your computer.

It is spoken in these cases as, “logic bomb” being a boot up type virus, installed in the boot sector of the boot device, i.e. the ‘drive’, (the MBR “master boot record or the ‘partition’”), floppy disk or possibly some other reading system replaces the program start-up or “boot loader” in (by copying from the original locations), but not similar to the program used to modify a common virus, because it replaces an existing boot disk, it acts as a virus “Set” (which is located in the beginning of the start up process), but the fact of contamination of the software starting device differs from traditional viruses.

It is understood by most that any computer virus are what are known as malicious software that have been designed to covertly spread to other computers by inserting itself into many legitimate computer programs named ‘guests.’ The problem is that the virus can now more or less critically damage the functions of any infected computer. These computer viruses are known to spread through any medium where there is an exchange of digital type data in any computer networks or even CD-ROMs, USB keys, and on and on, etc.

The name comes from an analogy with biological viruses, because there are similarities in the way that spreads to the reproductive capacity of the host cell. He writes the “computer virus” by the computer and the molecular biologist Leonard Adleman (Fred Cohen experimented with computer viruses, 1984). Computer viruses should not be mixed up with computer worms, which are programs that can spread and create a copy of their own, without contamination from the host program. In general, frequently used and misused is the word virus to some forms of malware which are yet to be classified.

The total number of known malware reaches up to about 95,000, according to Sophos (all types of malware). Nevertheless, the closest accurate number of viruses at present in circulation does not go beyond a few thousand, depending on the WildList Organization, every antivirus vendor with an interest in the “spirit” of viruses. The greatest impact are on Windows platforms. Although very small, there is a virus such as Unix / Linux systems, but no epidemic similar to the Windows virus was discovered in 2010. The rest is for operating systems that are spread in recent years only 27 virus – not one is dangerous – imposed on Mac OS 9 and its predecessors (written by John Norstad, author of antiviral disinfectant). The systems are the least affected of FreeBSD, which focuses on the development of safety, and NetWare and OS / 2 is too small for a developer known viruses. Viruses are often victims of false alarm that the spread of rumors, bulky loads etc.
