Viruses, worms, Trojan horses, and hacking are all security issues in our computer network. Each of these malwares or programs attaches and spreads in different ways. Through hacking hackers can infect computers with various types or malware and viruses. This paper will explain what viruses are, how it occurs and the types of cybercrimes that can result from it, and how to better protect your computer.
“Security warning! Application cannot be encrypted or Spyware alert! Your computer is infected by spyware. Do you want to activate your antivirus software now?” These are usually the messages that appear on your computer when it is infected by a virus. These are the types of viruses and message traps that hackers attempt to use to scam users into buying false antivirus software. Each type of these infectious malwares and programs by hackers are different and occur in various ways.
Viruses and hacking have a major impact on two main topics discussed in Computer Information Technology 110 (CIT 110). The topics are data security and operating systems. Through the infection of computer viruses and hacking, the computer’s operating system can malfunction and data’s security becomes vulnerable to loss or theft by hackers. As explained in Catherine LaBerta’s Computers Are Your Future textbook, the operating system (OS) is a “set of programs designed to manage and control the resources of a computer” (Laberta 111). A virus infection can impede operating system from properly function. This usually occurs when the virus is preventing the OS from opening any antivirus software.
People often confuse viruses for another type of malware or program such as worms and Trojan horses. As described by CommonCraft in Computer Viruses and Threats...

Beal, V. (2011, March 29). The difference between a computer virus, worm, and Trojan horse.
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.
I should start by saying that not every system oddity is due to a virus, worm, or bot. Is your system slowing down? Is your hard drive filling up rapidly? Are programs crashing without warning? These symptoms are more likely caused by Windows, or badly written legitimate programs, rather than malware. After all, people who write malware want to hide their program's presence. People who write commercial software put icons all over your desktop. Who's going to work harder to go unnoticed?

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.
Besides making copies of themselves, viruses can have other harmful effects. They can delete or change document contents, change Word settings, set passwords on your documents so that you can’t read them, or delete all of your files the next time you start your computer.
Computers are main technological features that allow criminals to step into unsuspecting victims lives. With a simple piggy-backing program hackers are able to track every keystroke made by the victim. One such program is called spyware, not to be confused with adware, which is often referred to interchangeably with spyware, but is potentially harmless (Louis 15). Spyware, hidden within downloaded software, implants itself deep within a computer’s hard drive, allowing it to track every move made by the user (Louis 16). Once inside a system, spyware can gather e-mail addresses, passwords, and credit card numbers.
“ Prevention is better than cure ”, if computer users are aware of Malware attacks, they may prevent those attacks . So, in this research paper i am going to focus on Malware and Protecting Against Malware.

The computer evolution has been an amazing one. There have been astonishing achievements in the computer industry, which dates back almost 2000 years. The earliest existence of the computer dates back to the first century, but the electronic computer has only been around for over a half-century. Throughout the last 40 years computers have changed drastically. They have greatly impacted the American lifestyle. A computer can be found in nearly every business and one out of every two households (Hall, 156). Our Society relies critically on computers for almost all of their daily operations and processes. Only once in a lifetime will a new invention like the computer come about.
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...
What is the “MALWARE”? A malware refers to software programs designed to damage or do other unwanted actions on a computer system. In Spanish, "mal" is a prefix that means "bad," making the term "bad ware" .Malware includes viruses, worms, Trojan horses, and spyware. Viruses, for example, can cause havoc on a computer's hard drive by deleting files or directory information. Spyware can gather data from a user's system without the user knowing it. This can include anything from the Web pages a user visits to personal information, such as credit card numbers.
The Art of exploring various security breaches is termed as Hacking.Computer Hackers have been around for so many years. Since the Internet became widely used in the World, We have started to hear more and more about hacking. Only a few Hackers, such as Kevin Mitnick, are well known.In a world of Black and White, it’s easy to describe the typical Hacker. A general outline of a typical Hacker is an Antisocial, Pimple-faced Teenage boy. But the Digital world has many types of Hackers.Hackers are human like the rest of us and are, therefore, unique individuals, so an exact profile is hard to outline.The best broad description of Hackers is that all Hackers aren’t equal. Each Hacker has Motives, Methods and Skills. But some general characteristics can help you understand them. Not all Hackers are Antisocial, PimplefacedTeenagers. Regardless, Hackers are curious about Knowing new things, Brave to take steps and they areoften very Sharp Minded..
In today’s days malware is designated as a software which aims to disturb a computer with the consent or permission of the owner. This term “Malware” is used by computer professionals to describe a varied forms of destructive, annoying and intrusive software code. This word “Malware” is used to indicate all types of malware which include a true set of viruses.
