Computer viruses
There are hundreds of thousands of viruses in the world and they usually designed for different purpose or objectives. Most of the computer viruses written in the early and mid-1980s were limited to self-reproduction and had no specific damage routine built into the code, but after more and more programmer acquainted with virus programming, they made viruses that can modify the data or even destroy them on infected computer. A co...

...mputers and various features to help extra protections. But most of them use same basic detecting methods such as real-time protection, signature-based on detection, heuristics detection and rootkit detection. In antivirus industries, the most significant job is to classify the known viruses based on their activities, even one single malicious programs have several malicious activities and propagation routine.

  • Book Review Of David Harley's Viruses Revealed?

    802 Words  | 2 Pages

    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.

  • Computer Hackers and Greed

    1873 Words  | 4 Pages

    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.

  • Trojans,Worms, and Viruses: What Are They and What Can You Do to Stop Them

    1690 Words  | 4 Pages

    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.

  • Malicious Code

    1628 Words  | 4 Pages

    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.
