Antivirus An antivirus is a program used to protect a computer from malware such as virus, Trojan horses, computer worms and other malicious programs. Besides from protecting a computer, the anti-virus offers many solutions to prevent new infections into your computer by scanning emails and files when they are being downloaded. An antivirus program is considered a security strategy. A computer virus is similar to a biological virus; it spreads from one computer to another just as the biological virus spreads from human to human. The computer virus infection is small software that can harm your computer; it disrupts computer function, and corrupts and wipes out data. The spread of a virus can occur in numerous ways. Ways that a virus can spread is through the opening of attachments to emails or other kind of messages, through downloading files from the internet, through visiting unknown websites and through installing un-trusted program files. One unique characteristic about a computer virus that differentiates from other malware is that a computer virus can only spread through human action. The computer virus can be on your computer without you knowing and the computer virus is only effective when you click on the infected program. A Trojan horse is a program that may see and legit software or files but once the program is executed, the damage comes into effect. The damage goes from being small, spamming programs into your computer and can go up to stealing computer data or even destroying and eliminating all information from computer. Through Trojans, computer hackers are able to hack into some one’s unit and remote control the computer. It all takes a simple click, from either you or the hacker to infect the computer.

A way to check id a virus is really a virus, you can upload it to VirusTotal and that program will tell one every detail of the program and define if the program is a virus. It’s really hard to choose the best antivirus solution for your computer. Of course we want the best security to protect our computer from malicious programs, but there are lots of programs to choose from. The criterion to find the best antivirus solution for you is reliability, usability, comprehensive protection and quality of protection. Personally I use Norton Antivirus because it contains multi-layered malware-fighting technology which many other antiviruses don’t have. Multi-layer means that it has protection layers that a virus needs to pass in order to reach and infect the computer.
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.
You know they're right. Yet for one reason or another, you're not running antivirus software, or you are but it's not up to date. Maybe you turned off your virus scanner because it conflicted with another program. Maybe you got tired of upgrading after you bought Norton Antivirus 2001, 2002, and 2003. Or maybe your annual subscription of virus definitions recently expired, and you've put off renewing.
What is virus? A computer virus, according to Webster's Collegiate Dictionary, is "a computer program usually hidden within another seemingly innocuous program that produces copies of itself and inserts them into other programs or files, and that usually performs a malicious action (such as destroying data)". Two categories of viruses, macro viruses and worms, are especially common today. Computer viruses are never naturally occurring; they are always man-made. Once created and released, however, their spread is not directly under human control. One example of a virus is the Anna Kournikova virus, which comes in the form of a picture sent through email.
They have the following characteristics: Advance (customized malware for a chosen target), persistent (used over an extended period for chosen target), and organized threat (Stallings & Brown, 2015). Because of the complexity of these threats, they are harder to defend, it requires a higher level of technicalities. “The aim of these attacks varies from theft of intellectual property or security and infrastructure related data to the physical disruption of infrastructure.” (Stallings & Brown 2015, P.
Malwarebytes Anti-Malware Free have some security features such as Anti- Malware/Anti-Spyware, Malwarebytes Anti-Rootkit and Advanced Malware Removal. [9] Anti-Malware/Anti-spyware feature as usual, this is for detects and delete malware such as, viruses, Trojans, worms, rootkits, adware, and spyware in computer system to make sure information security integrity. Malwarebytes Anti-Rootkit is for removes rootkits and repairs the files they damage. This feature is useful for the computer system which is after infected because it can restore the data integrity. Advanced Malware Removal is for employs industry-leading technology to completely remove malware code. This technology will help us to keep our data confidentiality can be maintain.
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 by the person behind the attack. Some hackers use the Storm Worm to create a botnet and use it to send spam mail across the Internet.
Computer Viruses are a form of malware that are small software programs that can spread to different computers. They cause interference to your computer’s operations,
“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.
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.
“ 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.
Is a computer virus similar to a human virus? Below is a chart that will show
In everyday use, the antivirus products help to protect the users who might be ignorant towards the basic “safe” usage of the computer systems, like clicking on unreliable links in mails and visiting unauthorized websites. In addition to this, few business also require basic desktop protection software in order to meet the requirements for regulatory compliance, for an example PCI DSS (Payment Card Industry Data Security Standard).
Malicious software, or simply malware, can be described as software that a computer user never authorized to be loaded. This means that the software can be found on user’s computer without his or her knowledge. Furthermore, a malware can be described as software that collects private information from any computer without user’s knowledge and authorization. As the name suggests, this software is malicious and can do great damage to a computer, mobile device, or other related devices. This damage can range from something as slight as altering the author’s name on a document to massive damage like making an entire device fail to function properly (Töyssy and Marko 109). The good news is that malwares can be controlled or prevented. As a matter of fact, it does not cost a fortune to keep a device safe from malware attacks. It also needs enough knowledge about them. In order to be able to do this, however, it is important to understand the various terminologies used to describe malicious software.
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.
Computer security is needed to protect the computer and the data that is stored or accessed in the computer. Computers are used on jobs, in schools, and for research. They also support critical business processes. Computers protect personal and sensitive information for businesses too. The meaning of computer security has changed over the years. In the past people did not have to worry about someone putting a virus on their computer, the only problem they had then was someone taking it from them. There were viruses, but they were used for the mainframe so they would not work, not for personal computers. Even at this time there were not a lot of personal computers in use. A lot of people could not afford them in the past. Then you had people that did not know what computers were and what they did. Now today you cannot find a person that doesn’t know what a computer is for. Today most people have at least one computer of some type in their homes. In the business world people would lock up the computers in the computer room to keep people from messing up the machine. The machines were too big to carry out. The main frames were massive machines that took up a lot of space. You did not have to worry about someone moving them. Today computer sizes are a lot smaller. These computers are portable so they can be carried off but that is not the main problem. The main problem come in to play when you have people stealing data off of your machine while you are on the internet surfing. All users want to prevent theft of their computer and theft to the data that is in their computer. Users do not want anyone to put viruses on their computer or anything that may damage the computer. Some business will only allow strict acce...
