<human>:  What is the difference between a virus and a malware?
<bot>: The key difference between a virus and a malware is that a virus is a type of malicious software that can replicate itself and spread to other computers, while malware is a type of software which has been designed to cause damage to a computer or network without the user's knowledge. Viruses can spread through downloading infected files or programs, exchanging files with another infected computer, or opening emails that have malicious attachments. Malware can spread through downloading malicious files, visiting malicious websites, or clicking infected links.
