Viruses are infectious programs that spread by attaching copies of themselves to other executable programs. They consist of reproduction, trigger, and action mechanisms. Benign viruses are used for maintenance and compression. Trojan horses are programs with hidden functionality, such as secretly capturing passwords. They can be encrypted or scattered in code, making them difficult to detect. Common types include remote access, data sending, and destructive Trojans. Trojan horses harm networks by consuming bandwidth and can erase, encrypt, or corrupt files on infected computers. Computer worms are self-replicating programs that send themselves to other nodes on a network without user intervention, unlike viruses which infect existing programs. Worms always harm networks.

This document provides information about computer viruses including what they are, where they come from, and why they exist. It defines a computer virus as a type of software that copies itself into other programs. Viruses can slow computers down or allow monitoring of user activity. The document discusses the history of viruses dating back to the first "Creeper" virus in the 1970s. It also outlines different types of malware like viruses, worms, and Trojan horses while distinguishing between their characteristics. Finally, it provides tips on how viruses are contracted and recommends installing antivirus software and being cautious of emails and external devices to prevent infections.
Computer Virus
Computer viruses are malicious programs that can copy themselves and infect other computers. Malware includes software installed without consent that can display advertisements or collect user information. Antivirus software detects and removes malware like viruses, worms, and trojans from computers. Computer worms are self-replicating programs that can copy themselves to other networked computers without user interaction.
Malware
Malware comes in various forms and can infect computers through many sources such as malicious websites, pirated software/media, and emails. There are three main types of malware: viruses, trojans, and worms, which operate differently to disrupt computers. Users can protect themselves by only visiting trusted sites, avoiding suspicious ads and emails, and using antivirus and firewall software to block unauthorized access and programs. Malware aims to access personal information and systems without permission.

Computer virus
- 2. Computer Virus • Malware • Spyware • Trojan Horse
- 3. Malware Malware, short for malicious software, is any software used to disrupt computer operation, gather sensitive information, or gain access to private computer systems. Malware is defined by its malicious intent, acting against the requirements of the computer user, and does not include software that causes unintentional harm due to some deficiency. The term badware is sometimes used, and applied to both true (malicious) malware and unintentionally harmful software.
- 5. Spyware Spyware is software that aims to gather information about a person or organization without their knowledge and that may send such information to another entity without the consumer’s consent, or that asserts control over a computer without the consumer’s knowledge.
- 7. Trojan horse A Trojan horse, or Trojan, in computing is any malicious computer program which misrepresents itself as useful, routine, or interesting in order to persuade a victim to install it. The term is derived from the Ancient Greek story of the wooden horse that was used to help Greek troops invade the city of Troy by stealth.
- 9. • Anti Virus • Fire wall
- 10. Anti Virus Antivirus software was originally developed to detect and remove computer viruses, hence the name. However, with the proliferation of other kinds of malware, antivirus software started to provide protection from other computer threats.
- 12. Fire Wall In computing, a firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted, secure internal network and another outside network, such as the Internet, that is assumed to not be secure or trusted.
