COMPUTER VIRUS

A computer virus is one kind of computer program that replicates itself by modifying other programmes. These viruses are responsible for several data manipulation processes, deleting several files and also responsible for reformatting any hard drives. These computer viruses also created hurdles and barriers in the case of performing any tasks through using the internet. There are several types of viruses that are able to disrupt the performance of a system and are responsible for having programming crashes multiple times. A computer gets viruses through different processes such as sharing images, files and music and visiting websites. 

3.1 Definition of  a computer virus 

Computer viruses are malware that spreads from computer to computer and causes several types of leakage of data, issues in major operations and causes disruption in a process. One should read the licensing and its agreement policy before installing software applications as they contain viruses in them. These viruses pop up several malicious windows and the computer gets slower than before. Nowadays, people share different types of spam mail or other attachments with an email that contains multiple viruses that are harmful to a computer system. However, different kinds of solutions have been created to mitigate those issues. 

3.2 Names of computer viruses 

There are different types of viruses that have been found in the online research process. Brief information about those viruses along with the computer virus names has been provided. There are viruses available – 

• Mydoom – $38 billion

It is one of the worst computer viruses that has been invented since 2004. It caused $38 billion which was spread through the mass emailing process. 

• Sobig – $30 billion

This virus was created in 2003 and affects Asia, Europe and Canada. It caused nearly $30 billion in all of these regions.

• ILOVEYOU – $15 billion

 This virus has been sent as a text file but it infects all the emails of the receiver computer system. This computer virus was invented in 2000 and caused $15 billion in total.

WannaCry – $4 billion

This is a ransomware virus that was invented in 2017. According to the research, it has been found that almost a total number of 150 countries have been affected by this virus. 

• Code Red – $2.4 billion

Code red virus was observed in 2001. This is a worm type virus that affects 975,000 hosts in total.

This section depicts the cost of these viruses that are one of the most renowned viruses worldwide. The first computer virus name is “The Brain Boot Sector Virus”. According to the research process, there is a total cost of $55 billion each year for cleaning up and protecting a computer from this virus attack. 

3.3 Impact of these computer viruses

These computer viruses cause several damages to a system and an individual faces issues and challenges in case of performing their particular task. These viruses slow down the functions of the computer and the system takes much more time to load than usual. People are unable to connect through the internet for performing their tasks as well as it also causes disruptions in the case of performing high-level control. However, several minds of online applications assure that viruses are cleaned up. Nevertheless, they are not that efficient in the case of performing those tasks; the owner is unable to remove those viruses from their systems. Viruses are able to reproduce themselves and spread from programme to programme. As a result, they have unwanted crashes in programmes 

3.4 Process to mitigate these computer viruses

There are several types of features and functionality available in the market that helps one to protect the computer system from virus attacks. One has to go through research in this process and use possible resources and information to have less threat. Those processes are as follows- 

• Usage of antiviruses and firewalls

• Through updating the browser system security

• Downloading software from trustable websites

• Delete several spam messages

• Update the antivirus protection of a computer system

There are processes that have been explained that are responsible for protecting a computer system from various types of computer viruses for a long period. One should look out for this process and act accordingly to have maximum protection. 

Conclusion 

In this article, there is a brief definition of computer viruses along with some names of those viruses. This depicts the invented years of those most affected by computer viruses and their effects. In this assessment, some of the impacts of those viruses have been explained and provided an overview of these viruses. Three are images of computer viruses available on the internet, with more information about them. However, in this context, some possible strategies and functions have been explained to get protection from attacks or such types of viruses. This article provides all information on the topic of computer viruses and is able to gain their attention to research more on this topic.
