A computer program is a set of instructions, written in a specific programming language, that a computer follows to perform a particular task or function. These instructions are designed to execute a sequence of operations that allow the computer to carry out desired actions, such as calculations, data processing, or automation of tasks.

Programs are essential for computers to function effectively, and they come in various types, including system software (like operating systems), application software (such as word processors), and utility programs (like antivirus software). However, while computer programs are beneficial, some malicious programs, known as viruses, pose a significant threat to computer systems.

Computer viruses are malicious programs designed to spread and cause harm to computer systems. Below are some common types of viruses and how they attack:

1. Email Viruses (E.M. Viruses)

These viruses spread as attachments to email messages and replicate themselves by automatically sending copies to other contacts in the recipient’s email list. A common example is when a user receives a message with a link claiming they have won a prize, such as an iPhone. Clicking on the link can lead to the installation of malware on the system

2. Trojan Horses

A Trojan horse is a deceptive program that appears to be useful or legitimate but contains hidden malicious functions. Unlike traditional viruses, Trojans do not self-replicate but can cause significant damage by creating backdoors for hackers, stealing sensitive data, or disrupting system functions.

It is important to use reliable antivirus software, be cautious with email attachments. Avoid downloading software from untrusted sources to reduce the risk of Trojan infections. Back up important data to prevent loss due to virus attacks.
