Computer Virus And Its Effect On The Computer

The users are recommended to scan the computer with an anti-malware program in case the user detect any out of the ordinary activities of the

To begin with, computer viruses are types of malicious software programs that replicate themselves by changing other computer programs and inserting their own code. This all happens when they get executed. This takes place when computers become infected with the virus, there are many reasons to why computers can become infected. Accepting without reading is by far the most common way a computer can become infected. This happens when a user just automatically accepts what they see on their screen without reading the prompt before continuing. For example, while on the internet an advertisement or a window may appear that says your computer is infected, without completely understanding what you’re getting, you accept the prompt anyways. Another reason to why your computer may become infected is by downloading any infected software. When downloading software such as programs, utilities, games, updates, demos, etc. always make sure you are downloading this software from reliable sources. Always read all prompts about what the program is installing onto your computer. Opening e-mail attachments can cause your

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

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.

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

Stallings and Brown (2012) provided an excellent categorization of malware. The primary categories are derived on the basis of propagation and payloads, where propagation contains types such as infected content, for example, viruses; vulnerability exploits, for example, worms; and social engineering, for example, spam e-mails and Trojans. On the other hand, the payload contains types such as system corruption; attack agent, for example, zombie and botnets; information theft, for example, key-loggers, phishing, and spyware; and stealthing, for example, backdoors and rootkits (Stallings & Brown, 2012).

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.
