...the basic concept of virus and provides an insight of the history of virus. The report also analyses the spread of viruses and defines certain measures that computer users may take into account to avoid viruses. Overall ,it was learnt from the report that it is important to keep us updated about computer viruses to be able to successfully safeguard us from computer virus attacks Introduction to Computer Virus: Viruses are mischievous programs, the purpose of which is to disrupt the sensible use of computers. It is a type of a mal-ware and do little more than display a message( Usually insulting!!!) on the screen , but some are designed to act after a certain period of time and do such things as make the letters start to drop off the screen or even erase the entire contents of your hard disk. As their name suggests, viruses are able to spread by infecting other disks and they do this by copying themselves onto other disks which are being used by the computer. Viruses are little programs or scripts that can create files, move files, erase files, consume your computer's memory, and cause your computer not to function correctly or to crash completely. Some viruses can duplicate themselves, attach themselves to programs, and travel across networks. They can self-modify or change over time as they copy themselves. Viruses only spread across multiple computers if an uninfected computer is connected to a network, or if the computer gets connected to infected...

...2012 Computer Virus: Do you own a laptop or a desktop computer? Have you ever experienced different weird action from it? Have you ever started writing a document, and it looks different, some chapters might be missing or something else abnormal has happened. For instance getting slow or when you turn the computer on, it says that all the data has been erased. NOOOO!! The first thing you do in situations like this is panic. You might think all that hard work you’ve done is all down the drain. That could be true, but in most cases viruses have not done any harm jet, but when some people try to get rid of viruses they delete files or they might even format the whole hard disk. Doing such isn’t the best thing to do when you think you have a virus infection. A good analogy to best explain what viruses are like is when people gets sick and you don’t know what’s wrong what do they do? They go to see a doctor to find out what’s wrong with them. It’s the same way with viruses, if you don’t know what to do you call someone who knows about viruses and get professional help. It is concluded that computer viruses is an important research area with potential applications to other fields, that current systems offer little or no protection from viral attack. (Fred). A computer virus is a computer program that can copy itself and infect a computer. The term "virus" is also used to refer to other types of malicious software, including: adware and spyware programs. A virus can spread...

...Computer Virus Good afternoon, ladies and gentlemen, I’m glad to bring my presentation for everyone. Before the start, I want to ask a question, I think most people like searching internet, someone like play computer games, someone like shopping, someone do other things. Whether you have the experience of account theft, information loss, and other internet security problems. So, today my topic relate these problems, computer virus. What is computer virus? CV is a computer program that can replicate itself and spread from one computer to another, and it cause the damage of computer function or destruction of data. Does anybody who knows the first computer virus in the world? Generally believed that as early as 1981, Apple gave birth to the first computer virus. In 1986 a personal computer virus, comes from a pair of Pakistan's brothers, Buster and Amjad for the purpose of preventing piracy written in C-the BRAIN virus. It is estimated that there are about 2 million mature hackers in the world, and over ten thousand new virus every day, the virus caused the loss of $ 100 billion annually. (1) Computer virus is a new derived in the form of computer crime A computer virus is a high-tech crime, transient, dynamic and random. Difficult to evidence, the risk of small damage, so stimulating crime awareness and crime activities. The virus does not come from the unexpected reason, most virus can be found in the author and origin information, from the statistical analysis of a large...

...How the virus and the hackers effecting today’s business world In the past decade, computer and networking technology has seen enormous growth. This growth however, has not come without a price. With the advent of the Information Highway, as it's coined, a new methodology in crime has been created. Electronic crime has been responsible for some of the most financially devastating victimizations in society. In the recent past, society has seen malicious editing of the Justice Department web page (1), unauthorized access into classified government computer files, phone card and credit card fraud, and electronic embezzlement. All these crimes are committed in the name of free speech. These new breed of criminals claim that information should not be suppressed or protected and that the crimes they commit are really not crimes at all. What they choose to deny is that the nature of their actions are slowly consuming the fabric of our country's moral and ethical trust in the information age. Federal law enforcement agencies, as well as commercial computer companies, have been scrambling around in an attempt to educate the public on how to prevent computer crime from happening to them. They inform us whenever there is an attack, provide us with mostly ineffective anti-virus software, and we are left feeling isolated and vulnerable. I do not feel that this defensive posture is effective because it is not pro-active. Society is still being attacked by highly skilled computer criminals...

...Skip to main content Open Problems in Computer Virus Research Steve R. White IBM Thomas J. Watson Research Center Yorktown Heights, NY USA Presented at Virus Bulletin Conference, Munich, Germany, October 1998 Abstract Over a decade of work on the computer virus problem has resulted in a number of useful scientific and technological achievements. The study of biological epidemiology has been extended to help us understand when and why computer viruses spread. Techniques have been developed to help us estimate the safety and effectiveness of anti-virus technology before it is deployed. Technology for dealing with known viruses has been very successful, and is being extended to deal with previously unknown viruses automatically. Yet there are still important research problems, the solution to any of which significantly improve our ability to deal with the virus problems of the near future. The goal of this paper is to encourage clever people to work on these problems. To this end, we examine several open research problems in the area of protection from computer viruses. For each problem, we review the work that has been done to date, and suggest possible approaches. There is clearly enough work, even in the near term, to keep researchers busy for quite a while. There is every reason to believe that, as software technology evolves over the next century or so, there will plenty of important and interesting new problems that must be solved in this field.

...is a computer virus? Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation. What do computer viruses do? Through the course of using the Internet and your computer, you may have come in to contact with computer viruses. Many computer viruses are stopped before they can start, but there is still an ever growing concern as to what do computer viruses do and the list of common computer virus symptoms. A computer virus might corrupt or delete data on your computer, use your email program to spread itself to other computers, or even erase everything on your hard disk. Computer viruses are often spread by attachments in email messages or instant messaging messages. That is why it is essential that you never open email attachments unless you know who it's from and you are expecting it. Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files. Computer viruses also spread through downloads on the Internet. They can be hidden in illicit software or other files or programs you might download. To help avoid computer viruses it's essential that you keep your computer current with the latest updates and antivirus tools, stay informed about recent threats, run your computer as a standard user (not as administrator), and that you follow a few basic rules when you surf the Internet, download files, and open attachments. Once a virus is on your computer, its...

...A computer virus is a computer program that can replicate itself[1] and spread from one computer to another. The term "virus" is also commonly, but erroneously, used to refer to other types of malware, including but not limited to adware and spyware programs that do not have a reproductive ability. Malware includes computer viruses, computer worms, Trojan horses, most rootkits, spyware, dishonest adware and other malicious or unwanted software, including true viruses. Viruses are sometimes confused with worms and Trojan horses, which are technically different. A worm can exploit security vulnerabilities to spread itself automatically to other computers through networks, while a Trojan horse is a program that appears harmless but hides malicious functions. Worms and Trojan horses, like viruses, may harm a computer system's data or performance. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious or simply do nothing to call attention to themselves. Some viruses do nothing beyond reproducing themselves. An example of a virus which is not a malware, but is putatively benevolent, is Fred Cohen's theoretical compression virus.[2] However, antivirus professionals do not accept the concept of benevolent viruses, as any desired function can be implemented without involving a virus (automatic compression, for instance, is available under the Windows operating system at the choice of the user). Any virus will by definition make...

...Computer Virus A computer virus is a malicious piece of executable code that propagates typically by attaching itself to a host document that will generally be an executable file. ✓ Typical hosts for computer viruses are: – Executable files (such as the ‘.exe’ files in Windows machines) that may be sent around as email attachments – Boot sectors of disk partitions – Script files for system administration (such as the batch files in Windows machines, shell script files in Unix, etc.) – Documents that are allowed to contain macros (such as Microsoft Word documents, Excel spreadsheets, Access database files, etc.) ✓ Any operating system that allows third-party programs to run can support viruses. ✓ Because of the way permissions work in Unix/Linux systems, it is more difficult for a virus to wreak havoc in such machines. Let’s say that a virus embedded itself into one of your script files. The virus code will execute only with the permissions that are assigned to you. For example, if you do not have the permission to read or modify a certain system file, the virus code will, in general, be constrained by the same restriction. ✓ At the least, a virus will duplicate itself when it attaches itself to another host document, that is, to another executable file. But the important thing to note is that this copy does not have to be an exact replica of itself. In order to make more difficult the detection by pattern matching, the virus may alter itself...

...A computer virus is a program that is designed to damage your computer, programs, and files. Like a virus in a living thing, a computer virus can spread if it is not removed. Some viruses are more dangerous than others. One of the most common places for a computer virus to appear is on a file found on the Internet or attached to an E-mail. Computer viruses didn’t really exist until the mid 1980s. The first computer viruses were created in university labs to demonstrate how much of a threat the vicious code could be. There are many kind of viruses that exist today. Some of the most common of Computer Viruses are: File Viruses, Boot Sector/Partition Viruses, Multi-Partite Viruses, Trojan Horses, File Overwriters, Polymorphic viruses, and Stealth Viruses. A File Virus is the most common kind of virus. These kinds of viruses usually infect .EXE and COM files, which are the main component of a program or application. A file virus can insert its own code into part of the file, so that when the infected program file is run, the virus is executed first. Most file viruses are memory resident. Because of this, they can easily attach themselves to other programs that are being run and start to infect that file. A simple virus will overwrite and destroy a host file, immediately letting the user know that there is a problem because the software will not run. Because these viruses are immediately sensed by the computer, they have a less chance to spread. More complex written viruses will cause...

...THE FUTURE OF TECHNOLOGY BY DEBRA JAMES WIU IT-330 Abstract Once before there was a business profit speed breaker called Macro Virus, and today it is still prevalent to a lesser extent, even though; Microsoft did do something about it, to where it is under control, but; still very much around. (Brightub articles 2011) .explains the well knows macro virus was a stark reminder of its disastrous power. In today’s world of technology computer viruses attack the software of a computer- the operating system usually attacks the software. (Microsoft /TechNet 2011), states the macro virus is known as a written virus in the internal macro language of applications. In some cases macro virus can cause no damage to the data, however; in other cases, macros viruses have been written that can cause damage to your work. This paper explains. What macro viruses are? How they spread. What affect they have? How to avoid a macro virus How to protect your computer What are Macro viruses…..? A macro virus is a computer infraction written in macro language, which is commonly built into word processing applications. (Goggle 2011, pg., 1) In general, Marcos viruses are a series of commands and executions that help automate specific tasks. Regardless of how many they create, they must be executed by a system that is able to interpret stored commands. There are some macro systems that are actually self-contained utilities while others are built into more advanced applications for users...

Nothing happens, your computer has just crashed due to a virus. And no it's not West Nile, Small Poxs or Polio. Computer viruses have been aroud for many years, since about 1986. Who invented computer viruses? Where were they created? Can you create them? All of these questions will be answered, as well as a short timeline of virus history and highlight of some recent major viruses. First, What is a computer virus? And how do you protect yourself from them? Then, A short timeline of virus' history. And, finally a few recent major viruses. What is a computer virus? A computer virus is a program or piece of software that copies itself to your PC, or attaches itself to a document. For example, when you open an infected document it replicates and attaches to other files on your hard drive. The process goes unnoticed until it is too late and your computer crashes. There are 3 types of computer viruses; E-Mail Viruses, Worms, and Trojan Horses. E-Mail Viruses- Many Hackers use E-Mail Viruses to reek havock on the E-World. (According to WWW.HACKERS.COM-Hackers are evil people who have nothing better to do with their vast knowledge of computers than destroy them.)

...According to the article”What is a Computer Virus” computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation. Computer virus can attack computers in many ways and are often damaging to the computer. These viruses often spread without a persons knowledge about the virus and can be specially damaging to computers and expensive to those who own the computers to repair. Viruses can also affect program and the performance of the computer and cause severe harm. The main component in describing a virus is the viruses’ ability to replicate itself through computers or the internet. The first computer virus was created by Dr. Cohen, 26 yrs ago at the University of Southern California. Dr. Cohen realized that if a Trojan horse copied itself into other programs, then all those programs would be infected, and then everybody that ran any of those programs would get infected and so forth (Lee). From here, Dr. Cohen has since developed many ways to remove viruses and is one of the leading experts in that field. One of the most difficult things with viruses are they come in all different forms and are often disguised to the user. One type of virus is a direct action virus. According to the article “Different Types of Computer Viruses” on buzzle.com, the purpose of a direct action virus is to replicate and take action when it is executed. When a specific condition is met, the virus will go into action and infect...

...English 101 5 May 2008 Antivirus Programs Today, people rely on computers to create, store, and manage critical information, many times via a home computer network. Information transmitted over networks has a higher degree of security risk than information kept in a user’s home or company premises. Thus, it is crucial that they take measures to protect their computers and data from loss, damage, and misuse resulting from computer security risks. Antivirus programs are an effective way to protect a computer against viruses. An antivirus program protects a computer against viruses by identifying and removing any computer viruses found in memory, on storage media, or on incoming files.1 when you purchase a new computer, it often includes antivirus software. Antivirus programs work by scanning for programs that attempt to modify the boot program, the operating system, and other programs that normally are read from but not modified. In addition, many antivirus programs automatically scan files downloaded from the web, e-mail attachments, opened files, and all types of removable media inserted in the computer [ (Karanos 201-205) ] One technique that antivirus programs use to identify a virus is to look for virus signatures, or virus definitions, which are known specific patterns of virus code. According to Shelly and Cashman (Antivirus Programs), many vendors of antivirus programs allow registered users to update virus signature files automatically from the web at no cost for a specific...
