Malware Viruses are: Worms, Trojan horse, most rootkits, spyware, dishonest adware, crime ware and other malicious and unwanted software.
Worms is a self-replicating program that sends copies of itself to other nodes through network without user intervention. Worm causes some harm to the system by consuming the bandwidth of the network.
Trojan horse is a non-self-replicating malware that appears to perform its function for the user but it gains unauthorized access to the user’s system and obtains the internal information of the system.
