What is difference between Virus and Anti-Virus? Write the names of some viruses.

A virus in the context of information technology is a type of malicious software (malware) that is designed to replicate itself and spread to other systems, often causing harm to data, software, and system functionality. It typically attaches itself to executable files, boot sectors, or documents, and once activated, it can execute harmful actions. These actions may range from corrupting data, stealing sensitive information, damaging software, or even rendering a system inoperable. A virus often requires human intervention, such as opening an infected email attachment or downloading malicious software, for it to spread.

The key characteristic of a computer virus is its ability to replicate itself and spread without the user’s knowledge or consent. Once a virus is executed, it may carry out its intended malicious activity, often without any immediate noticeable effects. However, over time, it may cause significant harm by consuming system resources, slowing down performance, or leading to data loss. Viruses can spread through infected files, software programs, infected media devices (like USB drives), and online activities such as browsing infected websites or clicking on malicious links.

The lifecycle of a virus typically involves several stages: infection, activation, propagation, and execution. In the infection stage, the virus attaches itself to a host program, file, or system. The activation stage occurs when the virus is executed, often triggered by an event such as _______ ___ _________ ____ _____ _____.
