Malware Types

Computer Virus: This is a computer program that can copy itself and infect a computer. It is also commonly but erroneously used to refer to other types of malware, adware and spyware programs that do not have the reproductive ability.

Computer Worm: A computer worm uses a computer network to send copies of itself to other computers on the network and may do so without any user intervention.

Trojan Horse: A Trojan horse appears to perform a desirable function for the user but instead facilitates unauthorized access to the user’s computer system.

Adware: Adware automatically plays, displays or downloads advertisements to a computer after the software is installed on it or while the application is being used.

Crimeware: Crimeware accesses a user’s online accounts at financial services for the purpose of stealing funds or making unauthorized transactions.

Rootkit: This is a program designed to gain control over a computer system or network of computing systems without being detected.
