Worms are programs that replicate themselves across multiple computers on a network or over the internet. Ransomware is a type of malware that restricts access to data until a payment is made. Spyware is software that monitors user activity and sends information about it back to the creator. Adware is software that displays unwanted advertisements while Rootkits are malicious programs designed to gain control of an operating system.
