VIRUS KIN is a term used to describe two types of malicious software, Worms and Spyware. Worms are self-replicating computer programs that can spread across networks without any user intervention. Spyware is a type of malicious software that is designed to collect information from a user's computer without their knowledge or consent. Both of these types of malicious software can cause serious damage to computers and networks, so it is important to be aware of them and take steps to protect yourself.
