How it work is by a number of ways first by shielding itself, normally starting off with an anti-virus firewall, so it scans files eliminates threats and informs you if a website is safe or not.

These days, there are thousands of different viruses and malware on Internet. Like the writers of viruses and other malicious code are many and diverse, and their reasons and motives that drive people to create a virus are as wide-ranging as themselves.

A virus is a software program that is designed to replicate between computers and affect the operation of the computer. A computer virus is similar to a human virus. A virus is a software program that is able to corrupt and delete data from the computer. The virus can be transferred from one pc to another through an email as an attachment.

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.

One of the most well-known types of malware among the general public is a virus. A computer virus is malicious software that infects a computer and then makes copies of itself, much like a biological virus. Before, viruses were spread through the use of floppy disks or USB flash drives. Nowadays, they are mainly spread through emails. Many phishing emails lead to webpages that download a virus onto the computer hardware. Viruses can corrupt computer files, making the computer unusable (Department of Homeland Security).

Malware, which includes all kinds of malicious software, was originally created to show the weaknesses of computers. The first type of malware, created in 1986, was a virus called “Brain.A. Brain.A was developed in Pakistan, by two brothers - Basit and Amjad. They wanted to prove that PC is not secure platform, so they created virus that was replicating using floppy disks” (Milošević). Even today malware is still used to check the security of machines.
