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. A botnet is a network of zombie computers that have been taken over by a robot or bot that performs large-scale malicious acts for the creator of the botnet.
Computer Viruses are programs that can replicate their structures or effects by infecting other files or structures on a computer.
The common use of a virus is to take over a computer to steal data. Computer worms are programs that can replicate themselves throughout a computer network, performing malicious tasks throughout.
Ransomware is a type of malware which restricts access to the computer system that it infects, and demands a ransom paid to the creator s of the malware in order for the restriction to be removed.
Scareware is scam software of usually limited or no benefit, containing malicious payloads, that is sold to consumers via certain unethical marketing practices.
