Effect of Virus on Performance of Computer System

Let’s say user (A) download an execution file (EXE) on his-her PC and double click on that file, if this file is infected the virus works based on the written code by the hacker/ attacker/ intruder and copy some files into the system. In case, user (A) does not have virus protection, the virus works perfect in destroying that computer or sending information from this computer to the attacker email. Viruses not only designed to destroy PC’s, but also designed to get information from

Computer virus is a program that can copy itself and infect a computer without the permission or knowledge of the user. Viruses perform some type of harmful activity such as accessing private information or corrupting

Computer- A computer the process-recieves in, thinks about, changes, stores, sends out, displays, and prints data in the form of bits.

A. Users at The Department of Social Services are constantly and consistently getting viruses on the organizations computers, also their boss has complained that the specific users are always unable to meet their deadlines. The employees logged onto their computers and downloaded music, works from unauthorized servers, save confidential files to the computer desktop instead of the shared drive, download music and unauthorized personal software on the organization computer system.

Literature Review: Research several types of information. Discuss several Pro and Cons positions by others and include at least 2 references for the Pro and Con arguments. This section should also clearly present both sides of the issue being discussed. Summarize the main issues on both sides by providing information on what the different sources say about the issue. Discuss at least two actual legal cases on your issue and their outcome.

Computer viruses have been around just about as long as the personal computer has existed. With the advent of the Internet, the ability of viruses to rapidly spread has increased substantially. Despite this increase in capability to infect large numbers of computers across international borders, the definition of a computer virus has not substantially changed over

For my research paper, I will be cover the situation of the Zeus virus which was a Trojan horse virus that infected window computers. This virus was used to steal login credentials which then allow them to use money mules to smuggle money overseas. More than 1,000,000 users were affecting by this and large company like Amazon, Oracle, Bank of America, and Cisco were victims. I found this to be interesting because of the way they were able to create value from being

Malware infections to hospital equipment and software systems can create a dangerous environment for patients. The Viruses can cause issues in patients monitoring equipment and can cause devices to become temporarily unusable. As stated in the article,” Computer Viruses Are "Rampant" on Medical Devices in Hospitals”, Many hospital systems are ran using older windows OS, which hackers tend to target often. Infections to the systems are usually originated from infections to the hospitals internal network, or infections from other devices such as laptops that our brought into the hospitals.

Literature searches will be carried out using Boolean operators, truncations and wildcards. This is done in order to avoid missing any important document that may be relevant to this review. Literature searches have been made accessible through the use of various electronic databases. These databases can subject specific or it could include all materials on different disciplines. However, it is safe to remember that not all relevant articles will be published in journals that have been indexed in these databases (Bowling, 2009). As a result of this, grey and unpublished literatures have to be

Viruses and worms are malicious programs that self-replicate on computers or through computer systems without the user being cognizant. Worms are a series programs that repeat themselves from system to system minus the use of a host fie. Worms use methods to infiltrate remote computers and launch replicas of themselves like email messages or coping files to an accessible disk. A computer virus is a

Computer viruses are minute program which is “embedded inside an application or within a data file which can copy itself into another program“(Adams et al, 2008 ) for the sole determination of meddling with normal computer operations. The consequences may range from corruption and deletion of data; propagation of virus on to network and deployment through attachments through emails in order to further creating havoc to all associated computing devices.

Just like a biological virus, a computer virus is able to infect and ruin lives. This malicious software constitutes more than just simple viruses but also includes other types of software including worms, Trojan horses, and ransomware. Malware has been around since the late 1980’s. Originally, people became hackers to gain notoriety online, but today, it has become more of a business. Cyber attacks originate from all around the world, and it is not just individual people that benefit from it. In two decades, numerous cyber crime syndicates have been created, and states all over the world sponsor hacker groups. Over the past twenty-five years, malware has become less about checking the integrity of computer security and gaining notoriety in the underground cyber society, and it has become more of a chaos creating, money making business that many people and institutions take part in.

Network viruses are another favorite method of cyber criminals. As we all know, viruses can bring a network to

Virus infection and inappropriate usage of systems by staff were the cause of most incidents, with viruses causing the greatest number of serious incidents. The average cost of an organization’s most serious incidents was roughly £10,000 ($96,000), and in large companies it was more like £120,000 ($235,200) (DTI, 2006).

A computer virus is Program or a portion of the codes that enter into the computer to target vandalism and characterized by their ability to copy itself to many copies and their ability to move from place to place and from computer to computer, disappearances and contents cover.
