Malicious wares Worms A computer worm is a program that self-propagates across a network

A Virus is a piece of malicious code that has the intent to damage your system.

Malware consists of viruses which are programs that attach themselves to legitimate programs on a victim’s machine. Worms are standalone programs that do not attach themselves to other programs. Direct propagation words take advantage of vulnerabilities in software. Blended threats propagate both as viruses and worms however; they post themselves on websites for people to download unwillingly. The payrolls are being nine they merely pop up Ace message on the victims computer screen or do something unknowing but nonlethal damage. Trojan horses, hides itself by deleting a system file and taking on the system file name. Remote access Trojan gives the attacker remote control of your computer. These items mentioned above do not rename themselves they can cause great damage or be just a nuisance.

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

a type of virus that spreads itself, not only from file to file, but also from computer to computer. the primary difference between a virus and a worm is that a virus must attach to something. such as an executable file, in order to spread. worms do not need to attach to anything to spread and can tunnel themselves into computers.

Each year there are many attempts to illegal gain entry into networks by attackers to steal information. Some attacks are designed to steal information while other may be to attack a system to cause damage or disrupt services. Attack can happen from anywhere in the world due to the internet and networks. A person from China can hack into an American network or such Stuxnet virus attack on Iran nuclear power plan which thought to be from Israel or United States but it is unsure where the virus originated from. According to Merkow & Breithaupt (2006), viruses caused the greatest financial loss over other computer crimes, (p 142). Worm is a type of virus which replicates and can easily infect a machine and then spread out across the network by using transport features of the computer or network.

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

Virus is a program that infect the computer system which is made by hackers to spy or steal users personal data, which is my cause a significant damage to the computer system.

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

Two of the common known attacks on computing systems are the deployment of computer viruses and malware.

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.

There are an enormous amount of malicious software programs. The most common types are known as viruses and spyware. Spyware has

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

There are special viruses that creates different types of malicious problems on a network or computer, for instance it will create or open programs to perform tasks. Viruses is also used for denial of service attacks, password cracking and many more. This can be fought against by having a reliable protection service; it is safer if this is taken from the provider itself.

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.
