Protection Against Viruses for All The word virus can be very disheartening, especially when computers areinvolved. A virus is composed of instructions hidden inside a program. Theseinstructions copy themselves to other programs, a nd the cycle continuesspreading. Fortunately, help is available; antivirus software is available toanyone. "Viruses first appeared in 1985. Then, they were largely created inuniversity laboratories by mostly wayward geniuses keen to pit theirprogramming skills against each other. Since then, errant programmers beganto create newer and more destructive viruses targeted at specific usergroups." (Yang, 1998) A computer virus can be as "evil as it sounds, snakingits way into personal computers, posing an occasional annoyance or a seriousthreat to all data." (Miastkowski, 1998) Symptoms can range from unpleasantto fatal. Computer viruses spread from program to program and computer tocomputer, "much as biological viruses spread within individual...members of asociety." (Chess, 1997) Diskettes were the "primary carriers of viruses inthe 1980s." ("Computer," 1997) Today, they are e-mail attachments, filetransfers and infected software downloads or uploads. Networks can evenspread viruses to large numbers of connected PCs rapidly. (Yang, 1998) Noone working on a [personal computer] is risk free; more viruses are beingspread today than ever before, but more help is being developed as well.Special software is now in stores that will help to prevent any majordisasters that viruses can cause. (Miastkowski, 1998) Antivirus software isa program that protects against viruses. It scans all files on the hard disk,diskettes, CD ROM, and memory to locate viruses. ("Computer," 1997) The life cycle of a virus is rather complicated; it begins when a user runsan infected program. The computer copies the program from the disk into RAM,random access memory, where it can be performed. The viral code begins torun, and the virus copies itself into a part of RAM that is separate from theprogram. This allows the pesky virus to continue to spread while anotherprogram is running, until it is finished and passes back into the infectedprogram. "When the user runs a different program, the dormant virus begins torun again. It inserts a copy...into the...uninfected software so that thecycle...can repeat." (Chess, 1997) There are also other computer pests suchas "worms" that effect networks, but viruses are the most common. (Yang,1998) Years of research have allowed scientists to find ways to detect and destroyviruses. (Chess, 1997) "Building on decades of research by mathematicalepidemiologists, [researchers] have obtained some understanding of the factorsthat govern how quickly viruses spread.
Also, implement patch management and keep up to date with anti-malware and anti-spyware updates. This helps in the summarization of the possible threats the College can face in certain scenarios and explains how to protect against them.
This virus searches for a new vulnerable host in order to survive and carry the disease to the next victim. The critical aspect around the spread of a virus is how drastically the reproduction process occurs. Without being controlled, the contamination throughout any species causes the spread to take place in a toxic way, “On day one, there were two people. And then, four, and then, sixteen. In three months, it’s a billion.
A computer virus is designed to self-replicate, self-install, and attack the root functions and system of different programs without authorization or the user’s knowledge. Virusesmainly affect the root of a computer system.Virus can destroy and damage most important part of our hard drive, the boot sector, where information about all files has been stored. Viruses may alter directory paths and may change
Imagine this; you are sitting at your desk looking at a bunch of pictures. Just a normal scene, what could go wrong? Suddenly, you’re attacked by deadly things that are trying to steal your personal information like your credit card numbers, email address, all your passwords, everything. Could this be the work of ninjas? No (bet that is what you first thought though). What about the FBI? No. Then what was it? It was a virus. If you hadn’t figured it out by now, you were looking at pictures online using Google images (for all you Bing fans, I’m sorry but Google is much better). You were downloading pictures from Google and one of them happened to contain a virus and it was downloaded with one of the pictures. How do I know this is a virus? The answer is that I don’t. I didn’t give enough symptoms to diagnose this. To the pros at hacking and security, you may know that viruses are not the only threat. If you are new to the world of computers, you might not. The three types of malware that will try to harm your PC or your data in any way are Trojans, worms, and the most famous, viruses. These three are very different and all are terrible for you and your PC.
Latency is the property shared by some viruses which allows them to persist indefinitely in
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 Morris; he was seeking a way of managing the internet in 1988. “Morris had no malicious intent, but a bug in his program caused many of the computers the worm landed on to crash. … but worms had come of age and have since evolved into an effective way of attacking systems connected to the internet” (Barwise). Today, hackers use the Morris worm to infect computers. “Five men believed to be responsible for spreading a notorious computer worm on Facebook and other social networks — and pocketing several million dollars from online schemes — are hiding in plain sight in St. Petersburg, Russia …” (Richmond). Since the good intended creation of the worm it has only been used maliciously as a computer virus by money seeking computer hackers such as the Koobface gang in Russia.
The hanta virus is not a new foe to humanity. This mysterious and sometimes fatal disease has plagued humanity for over 1000 years. This virus, most likely originating in China over 1000 years ago, is transmitted by human contact with mice. Only relatively recently has the hanta virus captured the attention of the United States. Although the hanta virus has been known for such a long time, there is little known about the virus. In the United States most cases are found in the southwestern part of the country, although cases have been reported from all four corners of the country. Recently, there have been successful tests done on prospective vaccines for the hanta virus. Despite this, strains of the hanta virus kill many people a year for lack of an effective medicine or vaccine (www.pharminfo.com).
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.
I decided to read the book by David Harley called Viruses Revealed. This book goes into great detail about the different kinds of viruses and virus mechanisms, the solutions to these viruses, studies on different cases of viruses and then the social aspects of viruses. In the first part of the book, Harley talks about the problems with viruses. A virus is a program that infects other programs to modify them. “Infecting means that a virus will insert itself into the chain of command” (Harley). The virus structure was defined into three different parts: Infection, Payload, and Trigger. The infection is defined as the way or ways in which the virus spreads. The payload is defined as what the virus does besides duplicating itself. Trigger is defined as the procedure that decides whether or not the payload is necessary. Harley also talks about the difference between damage versus infection. The major difference between the two is that many users have infected documents or applications on their computer. Whether or not those applications are run is the difference between the two. In part one Harley also converses about Trojan Horses. Trojan horses are normally known as a virus, but he shoots that down. Harley says that Trojan Horses are normally not viruses, but just a worm that goes from computer to computer. After talking about different kinds of viruses and worms, he goes into Anti-Virus softwares. There are two different kinds of anti-viruses. One being virus-specific. Virus-specific means that every time a virus is found on your computer, it is identified but not detected. Generic scanners do the opposite. Generic scanners detect viruses but do not identify them.
The history of cybercrime goes back to 1971 and the first computer virus called the Creeper which was created by Bob H. Thomas, who was a BBN engineer (Dalakov, Meltzer, and Phillips). BBN which stands for Bolt, Beranek and Newman, is now Raytheon BBN Technologies (“About”, Dalakov). A computer virus is a program that is created to cause damage to a computer or perform other malicious acts (204). The Creeper virus was designed to infect the ARPANET network. The ARPANET, which stands for Advance Research Projects Agency was set up by the U.S. Government as an agency in 1969 to provide a network of computers that would connect various academic and research organizations; it was the predecessor of the Internet (“Internet”, Morley, and Parker).
Computers; they are a part of or in millions of homes; they are an intricate part of just about every if not all successful businesses, the government, and the military. Computers have become common place in today’s society and the lives of the people who live in it. They have crossed every national, racial, cultural, educational, and financial barrier, which consequently ushered in the information age. A computer is a programmable electronic device that can store, retrieve and process data, and they come in all shapes, and sizes. They can be used for and in just about anything. As stated before, they are used in just about every aspect of modern society. They are so fundamental to modern society that it would be disastrous to society without them. As stated before, there are many areas in modern society that are run by computers. They play an intricate part of millions of homes in the world. Office workers in business, government and the military may use them to write letters, keep rosters, create budgets, find information, manage projects, communicate with workers, and so on. They are used in education, medicine, music, law enforcement, and unfortunately crime. Because computers have become such a part of the world and how it operates, there is a tremendous responsibility for those who are in control of these computers and the vital information that they carry, to manage and protect them properly. This is management and protection is vital because any loss or damage could be disastrous for the affected entity. For example, a mistake or intentional alteration of a personal credit file could affect ones ability to buy a car or home, or can lead to legal actions against the affected person until the mistake or intentional alteration has been corrected. Therefore, with the advent of computers in the information age, and all of the intentional and unintentional violations against them, comes the need to safeguard them and the information they carry with strong systems and policies of computer security.
Malicious code is a real danger to modern systems. Most systems nowadays do not work in isolation; they are more likely to be connected to other systems and sometimes they can even be dependent on them. Therefore an attack on one of the systems in the network is a potential attacking attempt to any other systems, with which it is interacting. Therefore, it is inevitable for any networked or Internet-connected computers to deal with malicious code attacks at some point. Businesses lose billions of dollars each year because of malicious code attacks. Responding to the attack and restoring all the data on the computers is a time-consuming and expensive task. It is a much better practice to try preventing it through organizing and maintaining effective defenses. However, it is important to keep in mind that there is no one general solution that can help to prevent all the attacks. Attackers are constantly looking for new ways to take advantage of systems’ vulnerabilities and find new ones. That’s why organizations have to not only defend themselves against existing attack methods, but also try to predict and prevent new attacking techniques. It means that computer and network security is a never-ending challenge and expense.
Virus is one of the most common malware. Unlike spyware, virus is largely designed to harm useful programs or wreck down an entire operating system. There are many ways through which virus may enter a computer. The most common way is via email attachments. A...
“A digital world we became”. These days individuals turned to use computer systems in everything in their lives. They even use them in manufacturer instead of employees. I did not say that technological innovation is not essential for us but sometimes the technological innovation disregards our role in life. Technological innovation is very essential to any lifestyle to flourish. Technology contains cell mobile phones, laptops, machines, Ipads and many other factors. Not also they include all the excellent stuff but any great factor comes out with a drawback. Technological innovation has some drawbacks, and the most essential one of them that we will mainly talk about is the malware.
Malware can survive in a number of ways say different sizes, shapes and also the purpose ranging from viruses to spyware and to bots. Malware in general is classified into two types. They are the concealing malware and infectious malware. In case of infectious malware, the malware code is said to spread all over which means that the software code shall replicate from one user to another and this goes on. In infectious malware, we need to consider two cases, which are called the viruses and the worms. Viruses are termed as the software that has executables within itself and causes the executables to spread when it is run. The second case called worms is a software which infects a computer and then spreads to others.
