Computer Security

  • Computer Security
1. What is a computer virus?

Computer virus is a program designed to spread itself by first infecting executable files or the system areas of hard and floppy disks and then making copies of itself. Viruses usually operate without the knowledge or desire of the computer user.

2. What kind of files can spread viruses?

Viruses have the potential to infect any type of executable code, not just the files that are commonly called 'program files'. For example, some viruses infect executable code in the boot sector of floppy disks or in system areas of hard drives. Another type of virus, known as a 'macro'
virus, can infect word processing and spreadsheet documents that use macros. And it's possible for HTML documents containing JavaScript or other types of executable code to spread viruses or other malicious code.

Since virus code must be executed to have any effect, files that the computer treats as pure data are safe. This includes graphics and sound files such as .gif, .jpg, .mp3, .wav, etc., as well as plain text in .txt files. For example, just viewing picture files won't infect your computer with a virus. The virus code has to be in a form, such as an .exe program file or a Word .doc file, that the computer will actually try to execute.

3. How do viruses spread?


When you execute program code that's infected by a virus, the virus code will also run and try to infect other programs, either on the same computer or on other computers connected to it over a network. And the newly infected programs will try to infect yet more programs.


When you share a copy of an infected file with other computer users, running the file may also infect their computers; and files from those computers may spread the infection to yet more computers.

If your computer is infected with a boot sector virus, the virus tries to write copies of itself to the system areas of floppy disks and hard disks.
Then the infected floppy disks may infect other computers that boot from them, and the virus copy on the hard disk will try to infect still more floppies.
Some viruses, known as 'multipartite' viruses, can spread both by infecting files and by infecting the boot areas of floppy disks.

4. Where is the virus located?

Boot sector viruses alter the program that is in the first sector (boot sector) of every DOS-formatted disk. Generally, a boot sector infector executes its own code (which usually infects the boot sector or partition sector of the hard disk), and then continues the PC bootup (start-up) process. In most cases, all write-enabled floppies used on that PC from then on will become infected.


5. What do viruses do to computers?

Viruses are software programs, and they can do the same things as any other programs running on a computer. The actual effect of any particular virus depends on how it was programmed by the person who wrote the virus.


Some viruses are deliberately designed to damage files or otherwise interfere with your computer's operation, while others don't do anything but try to spread themselves around. But even the ones that just spread themselves are harmful, since they damage files and may cause other problems
in the process of spreading.

Note that viruses can't do any damage to hardware: they won't melt down your CPU, burn out your hard drive, cause your monitor to explode, etc. Warnings bout viruses that will physically destroy your computer are usually hoaxes, not legitimate virus warnings.

6. What is a Trojan horse program?

A type of program that is often confused with viruses is a 'Trojan horse' program. This is not a virus, but simply a program (often harmful) that pretends to be something else.

For example, you might download what you think is a new game; but when you run it, it deletes files on your hard drive. Or the third time you start the game; the program E-mails your saved passwords to another person.


Note: simply downloading a file to your computer won't activate a virus or Trojan horse; you have to execute the code in the file to trigger it. This could mean running a program file, or opening a Word/Excel document in a program (such as Word or Excel) that can execute any macros in the document.

7. How can I avoid infection?

There is no way to guarantee that you will avoid infection. However, the potential damage can be minimized by taking the following precautions:

* Make sure you have a clean boot disk - test with whatever (up-to-date!) antivirus software you can get hold of and make sure it is (and stays) write-protected. Boot from it and make a couple of copies.

* Use reputable, up-to-date and properly-installed anti-virus software regularly. (See below) If you use a shareware package for which payment and/or registration is required, do it. Not only does it encourage the writer and make you feel virtuous, it means you can legitimately ask for technical support in a crisis.

* If you use a shareware/freeware package, make sure you have hard copy of the documentation *before* your system falls apart!
* Always run a memory-resident scanner to monitor disk access and executable files before they're run.
* Scan pre-formatted diskettes before use.

The Great Challenge to Produce

The Great Challenge to Produce
One Chapter Like the Chapters
of the Holy Quran
تحدي رب العزه جل وعلا بان يأتو بسورة من مثله
قال تعالى " وإن كنتم في ريب مما نزلنا علي عبدنا فأتوا بسورة من مثله وادعو شهدآءكم من دون الله إن كنتم صادقين "



God has said in the Quran:

And if you are in doubt about what We have revealed (the Quran) to Our worshiper (Muhammad ), then produce a chapter like it, and call your witnesses (supporters and helpers) besides God if you are truthful. And if you do not do it, and you can never do it, then fear the Fire (Hell) whose fuel is men and stones. It has been prepared for disbelievers. And give good news (O Muhammad) to those who believe and do good deeds, that for them are gardens (Paradise) in which rivers flow.... (Quran, 2:23-25)
Ever since the Quran was revealed, fourteen centuries ago, no one has been able to produce a single chapter like the chapters of the Quran in their beauty, eloquence, splendor, wise legislation, true information, true prophecy, and other perfect attributes. Also, note that the smallest chapter in the Quran (Chapter 108) is only ten words, yet no one has ever been able to meet this challenge, then or today.1 Some of the disbelieving Arabs who were enemies of the Prophet Muhammad tried to meet this challenge to prove that Muhammad was not a true prophet, but they failed to do so.2 This failure was despite the fact that the Quran was revealed in their own ******************************** and dialect and that the Arabs at the time of Muhammad were a very eloquent people who used to compose beautiful and excellent poetry, still read and appreciated today.



The smallest chapter in the Holy Quran (Chapter 108) is only ten words, yet no one has ever been able to meet the challenge to produce one chapter like the chapters of the Holy Quran.

Quran as a miracle

Quran as a miracle
القرآن الكريم المعجزة



The Quran is truly a living miracle. Going deeper into it, one finds amazing characteristics from every perspective.
In ********************************


 



The Arabs of the 6th and 7th centuries CE were masters of the Arabic ********************************. Eloquence and rhetoric were their lifeblood. The liveliness that marked their gatherings, the gaiety of their fairs, and the virtues of which they boasted, all found expression through poetry and literature. They were so proud of their literary accomplishments that they disdainfully dubbed all the other peoples of the world as “’Ajam” or “Dumb.” It was in this atmosphere that there appeared on the scene an unlettered person, Muhammad مواضيع اسلامية باللغة الانجليزية . He presented before them an oration, and declared it to be the Word of Allaah, which claimed (what means):
“If mankind and the jinn were to gather together to produce the like of this Quran, they could never produce the like thereof, even if they backed up one another.” [Quran 17:88]
Such a proclamation was an amazing thing. It came from a person who had never learned anything from the renowned poets and scholars of the time, had never recited even a single piece of poetry in their congregations, and never attended the company of soothsayers. And far from composing any poetry himself, he did not even remember the verses of other poets. This proclamation, repeated several times in the Quran, was therefore the greatest challenge to their literary expertise, and at the same time a fatal stab at their polytheist creed and beliefs. Following this, a hush fell over the whole galaxy of these stirring orators and fiery poets. Not a soul stepped forward to accept the challenge of producing the like of the Quran. They persecuted the Prophet مواضيع اسلامية باللغة الانجليزية called him insane, a sorcerer, poet and soothsayer, but failed utterly in composing even a few sentences like the Quranic verses. To this day, the challenge has remained unmet, although throughout history and even in modern times, many people have made feeble attempts to do so.
In Prophecies
Among other things, the Quran contains prophecies of future events, many of which have come to pass. We reproduce here a discussion of one such prophecy, which was fulfilled within the lifetime of the Prophet Muhammad مواضيع اسلامية باللغة الانجليزية.
While the Prophet مواضيع اسلامية باللغة الانجليزية was still in Makkah, after having been entrusted with prophethood, and was being subjected to all sorts of persecutions by the Makkan idolaters, exactly at the same time the two great powers of Rome and Persia were involved in repeated wars. The Romans were beaten, vanquished and suffered a great loss in men and material. At last, the Romans were so utterly exhausted that, far from being in a position to launch a counter-attack, they could not even take a firm stand anywhere. This situation was a matter of jubilation for the pagans of Arabia, as they identified the Persians, being fire-worshippers, with themselves and the Romans, as “people of the Book,” with the Muslims. In their eyes, the dominance of the Persians, presaged their own victory and the defeat of the Muslims. It was under these circumstances that these initial verses of the chapter called Ar-Room (The Romans) were revealed (which mean):


“…The Romans have been defeated, in the land close by. And after (this) defeat of theirs, they will soon be victorious within a few years. To Allaah belongs the command before and after and on that day the Believers will rejoice in Allaah’s help…” [Quran 30:2-4]
For those who were aware of the military situation concerning the Romans and Persians, this prediction was absolutely incredible. In fact, the Persians kept marching forward until they reached the city walls of the Roman capital, Constantinople. The renowned historian Edward Gibbon has commented on this prediction thus:
“When this prophecy was made, no prediction could be more unbelievable because the initial twelve years of Heraclius were evidently declaring an end to the Roman Empire.” [Fall of the Roman Empire, v.5, p.73-74]
But exactly seven years after his first defeat, the Roman emperor sallied forth from the capital and inflicted crushing defeats on the Persians at several places, and after that the Roman armies were victorious everywhere.
Meanwhile, a large number of Muslims had migrated to Al-Madeenah and their wars with the idolaters of Makkah had already begun. The day on which 313 ill-equipped Muslims were decisively beating their enemy -- 1000 heavily armed Makkan warriors -- at the battlefield of Badr, came the news that the Romans had defeated the Persians. It was then realized that the Quranic verse, (which means): “…on that day the Believers will rejoice in Allaah’s help” [Quran 30: 4-5] was meant to denote the twin happiness of the Romans’ victory as well as their own victory at Badr.
In Science and History
Apart from prophecies, the Quran has pointed out many scientific and historical facts which were not only unknown at that time, but could not even be imagined given the development of civilization. Entire books have been written (by both Muslims and non-Muslims) confirming the correspondence of scientific discoveries to the truths expressed in the Quran. Again, we suffice here with two examples:
The Quran has stated that as Fir’awn (Pharaoh) was drowning in the sea he made a confession of faith orally, just to save his life. In response, Allaah Said (what means):
“What! Now? And indeed before this you did rebel and were of the corrupt. So this day We shall rescue you with your body that you may be a sign to those who come after you.” [Quran 10: 91-92]
At the time of revelation of this verse, and even centuries afterwards, nobody knew that the body of Fir’awn had been preserved, but it has been discovered only recently and is preserved in a museum at Cairo.
The Quran has stated (what means): “And of everything We have created pairs that you may take heed.” [Quran 51: 49]
When this verse was revealed, the general concept was that male and female pairs existed only among human beings and animals or in some vegetation. However, with the advancement of science, the Quranic reality is becoming manifest that male and female pairs exist in everything. In some instances they are termed as male and female, and elsewhere as positive and negative, as electron and proton, or neutron and positron. In another verse, the Quran has also clarified that the occurrence in pairs in many other things is still unknown to people. It says (what means):
“Glorified be He Who created pairs of all things which the earth grows, and of themselves (humans), and of that which they know not.” [Quran 36: 36]
A Miracle For Us!
Looking back through history, it has been observed that the prophets, may Allaah exalt their mention, were sent with miracles that reflected the society and knowledge of the people they were sent to. Thus, Moosaa (Moses) مواضيع اسلامية باللغة الانجليزية was sent with a staff that truly turned into a snake, baffling the trickster magicians of the Pharaoh. ’Eesaa (Jesus) مواضيع اسلامية باللغة الانجليزية was given the power to cure diseases and give life to the dead, astonishing the Jewish doctors who felt proud of their limited knowledge of healing, and who had begun to disregard and deny the supernatural powers of God.
Similarly, the Quran was an immediate miracle for the Arabs so many years ago, since it challenged and far surpassed the limits of their literary expression. Unlike the miracles of previous prophets, which were only applicable for a limited time, to this day the Quran -- the Final Testament given to the Last Prophet مواضيع اسلامية باللغة الانجليزية -- is still a relevant miracle for humanity and will remain so as long as the world exists. We live in an age of science and technology, of knowledge, logic, and reason. Yet, in spite of all the human advancement in every sphere of life, the principles of the Quran have not been proven wrong nor have they become “out-of-date.” This is really the great miracle of the Quran, it has proven itself a timeless, universal message for humankind, relevant to every facet of our life — be it politics, economics, ethics, science, literature, arts or entertainment. In fact, even non-Muslim scholars have admitted that the entire “Western” civilization today, thriving from the “rebirth of humanity” (i.e. the “Renaissance”), would not have been so, had it not been for the message brought by Muhammad مواضيع اسلامية باللغة الانجليزية. As the celebrated English writer, Robert Briffault, says in The Making of Humanity:
“The ideas of freedom for all human beings, of human brotherhood, of the equality of all men before the law of democratic government, by consultation and universal suffrage, the ideas that inspired the French Revolution and the Declaration of Rights, that guided the framing of the American Constitution and inflamed the struggle for independence in the Latin-American countries were not inventions of the West. They find their ultimate inspiration and source in the Holy Quran. They are the quintessence of what the intelligentsia of medieval Europe acquired from Islam over a period of centuries through the various societies that developed in Europe in the wake of the Crusades in imitation of the


brotherhood associations of Islam. It is highly probable that but for the Arabs, modern European civilization would never have arisen at all, it is absolutely certain that but for them, it would never have assumed that character which has enabled it to transcend all previous phases of evolution.”

Signs and theories of aging


Aging Theories                      This report outlines the main theories of how the process of aging works. Since researchers have not discovered a universally-accepted theory of aging, the theories discussed are potential explanations of how we age. The likelihood of each hypothesis is considered roughly equal. The different theories discussed focus on the workings of different parts of the body, from the molecular level of DNA mutations and replication, to the organism level of becoming “worn out.” Aging is a very complex and gradual process, and its ongoing operation is present to some degree in all individuals. It is a journey to the maturity, as well as to the degeneration of the body. Because aging affects every part of the body, many different steps are involved and various types of reactions occur. Changes in DNA take place, which can and often do affect the way the body functions; harmful genes are sometimes activated, and necessary ones deactivated. A decrease in important body proteins like hormones and certain types of body cells is almost inevitable. These, among many, are characteristic changes that take place in our bodies as time moves on and aging continues. At present, a universal explanation for how we age or why we age does not exist, but there are many theories to explain this puzzle, and they are supported by continuous research. In this report, some of the how theories of aging will be examined. Among them are theories concerning spontaneous mutations, damage from free radicals, the clock gene, cellular aging, a weakened immune system, wear and tear, and hormonal and neuroendocrinous changes. Spontaneous Mutations The spontaneous mutations theory, also known as the somatic mutation hypothesis, states that the crucial events that cause aging are mutations. These
are changes in a cell=s DNA, which are passed on to daughter cells during mitosis. Since genes on DNA
 code for specific proteins, mutated genes may produce defective proteins, which do not work properly.
