It will look at what a virus is and what they do it will also look at why people create viruses and for what purpose. The report will also look at examples of famous well known viruses and the ways you can defend against viruses. What is a Virus? Firstly this report will look at the definition of a computer virus. This definition taken from Microsoft (n.d.) tells us what a virus is “Computer viruses are small software programs that are designed to spread from one computer to another and to interfere
• A computer virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. They have the ability to replicate themselves to the point of using all the available memory, slowing the machine or bringing down the system. All computer viruses are man-made. An even more dangerous type of virus is one capable of transmitting itself across networks and bypassing security systems. Type of Virus • File infecting virus This type of computer virus
The Evolution of the Computer Virus Introduction In simple terms a virus can be defined as software, which is unwanted and executes arbitrary code on systems. It acts as a small software program, which has the capability of exploiting other software programs in order to piggyback[1]. The terms viruses and malwares are used interchangeably, however, in technical terms, the viruses are a subset of malware and so are trojans, worms and rootkits. The name for the “Computer Virus” has actually derived
Introduction Our problem deals with computer viruses but not just computer viruses, also their affect on hard drives. Computer viruses affects on hard drives can be harmful and possibly irreparable. The computer viruses effects on the hard drive depends on the computer virus and what damage it does to the hard drive. One computer virus might do one thing to your hard drive while another virus could do something completely different. This is why we have designed a website that will help you to look
and Lies About the Computer Virus Walk into any computer store today and there will be at least twenty or thirty computer virus programs. From the looks of it computer viruses have gotten out of hand and so has the business of stopping it. The computer user must cut through the media hype of apocoliptic viruses and shareware programs and discover the real facts. Before we even start the journey of exploring the computer virus we must first eliminate all the "fluff." The computer user needs to understand
In 1998, Chernobyl virus affects computers that are running Windows; it is one of the most viruses destructive, written by Taiwan's "Shan Ling is", the name "Chernobyl" in relation to "an incident Chernobyl" that took place in Ukraine in 1986 because of an explosion at a nuclear reactor. Chernobyl virus scans the boot drive to become the device is unable to load. At the same time it is trying to clear the BIOS," the basic Input/output System instructions that tell the computer to start", which often
theirselves from digital threats. In order for people, to protect themselves, they must be aware of the basic types of malicious software, how they are spread and how to combat them. The generic virus is software which has been designed to do harm to a computer, replicate itself, and spread to other computers. While viruses can be spread via CDs and USB drives, the most common way for them to be distributed is through email attachments.(Brown 20-21) Email viruses have been known to search an infected
What is a computer virus? A computer virus is a piece of malicious code that is capable of copying itself and typically has a detrimental effect such as corrupting a system or destroying data. Computer viruses are written with the sole intention of stealing data or crippling a system. The term computer virus is derived from and is in some sense analogous to a biological virus. The word virus itself is Latin for poison. Simplistically, biological viral infections are spread by the virus (a small shell
Process Essay - How to Recognize and Eliminate Macro Viruses Imagine starting up your computer only to see the image on the screen melt while eerie music plays. The hard drive crunches away. What is it doing in there? Before you turn off the machine, most of your files have been deleted. Your computer is the victim of a computer virus. But where did the virus come from? It may have been that game you borrowed or, more likely, it came from an electronic document. Most viruses infect programs
are deadly to your computer. Still others are humorous and entertaining. There are many dangers on the Internet. This paper will try to cover some of them. The biggest dangers of the Internet are virus. Viruses are small programs that "infect" computers. Most viruses are made to "steal" and or "destroy" data stored on the infected computer. Viruses, that destroy data, write their code into a file and when that file is accessed it rewrites itself in to more files until the virus corrupters or "infects"
Same as any other area in computer science, viruses become a great deal indeed throughout the years. Return to the origin of computer viruses, although there were no viruses or worms developed, Mathematician John Von Neumann had described the theories of self-replicating programs in 1949. In 1971, Bob Thomas has developed “The Creeper Virus”. It was an experimental self-replicating program. It infected DEC PDP-10 Computers to run the TENEX Operating System. The Reaper program was later developed
Multi-platform computer worms are a tool that computer hackers use to infect computers to gain control access. Computer worms are a dangerous virus because they are self-replicating, meaning that they multiply themselves and spread onto other computer networks seeking a lapse in internet security. Computer worms do not need to attach themselves onto an existing computer program to gain access to the victim computer files. The computer worm was created on accident by a Cornell student named Robert
lines. Computer viruses are every bit as harmful and destructive, and come in a vast variety of types and strains. Computer viruses, can tear up your hard drive and bring down your system. However, unlike social diseases, computer viruses are almost always curable, and the cures for new strains are usually a matter of days away, rather than months or years. A computer virus is a program designed to replicate and spread, generally with the victim being oblivious to its existence. Computer viruses

At the Aim Higher College there have been recently discovered malware on the campus systems that are due to many recent attacks. I used an Anti-virus protection software called AVG on the computer systems on campus and ran a whole computer scan. The results came back very quick of numbers of malware being high and medium priorities that these should not be taken lightly. Furthermore, the scan found many viruses, Trojans, and malicious software and applications. The first finding was a medium priority
Trojan Horse and Trojan Virus. Today people know the “Trojan” or “Malware” as a computer virus. Trojan horses falsely show themselves as useful and valuable software to download from the Internet. People are fooled by the Trojan because it can describe itself as an application that can be useful on your computer, then people end up downloading them. But before that happens did you know that the Trojan itself is not dangerous at all it’s just a vessel for the other harmful applications to attach
Computer Virus Description: Storm Worm Impact: An official with the security company Postini claimed that the firm detected more than 200 million e-mails carrying links to the Storm Worm during an attack that spanned several days Example of a Computer Virus: The Storm Worm is a Trojan horse program. Its payload is another program, though not always the same one. Some versions of the Storm Worm turn computers into zombies or bots. As computers become infected, they become vulnerable to remote control
research done at the AV-Test Institute, over 220 thousand malicious programs are recorded on a daily basis as a result of malware. The malicious software or malware, according to the Bull Guard Security Centre, refers to computer programs that are created to interfere or destroy computers functioning, without the users consent. Malware can take the form of worms, viruses, Trojans and spyware threats that can interrupt any data systems safety and even lead to denial of access to information on such system
ask, ‘Why computer viruses are constructed and Its effects on computer users? Therefore, the answers are argumentatively acknowledged by the different authors and explanations of the consequences in causing computer viruses. Because it is a huge problem in today’s world. The paragraphs are mainly focused in four areas, the causes of computer viruses, the economic impacts on government intelligence nuclear, also stealing sensitive information. These are all critically affected by computer viruses
technology affects a society. He introduces us to a world where a computer virus is altering people's minds, and where they have no control over themselves. He vividly describes how Hiro, the protagonist, must fight the virus to save the future of the world. Technology is expanding everyday. Our society has grown and expanded and has become extremely powerful because of new technologies. People are learning how to use computers in place of their tasks. The Internet is a prime example is of expanding
