Malware is a programme that is made to access computer systems without the user's consent. 

Key Points

  • Examples of malware are Ransomware, spyware, Trojan horses, and worms. 
  • Trojan typically appears as a harmless email attachment or free download. 
  • A Trojan is a programme that has been downloaded and installed on a computer that pretends to be harmless but is actually harmful.
  • The email attachment's concealed virus gets downloaded to the user's computer when they click on it or download the free programme. 
  • Trojans cannot propagate or replicate themselves.

Thus, a destructive computer program that masquerades as a useful application is called a Trojan. 

Additional Information

  • Firmware: It is software that offers fundamental machine instructions so that hardware can run and interact with other programmes that are installed on a device.
  • Virus: It is a little piece of software that travels from computer to computer and obstructs normal operation.
  • Worm: A computer worm is a subset of Trojan horse malware that, once infiltrating a system, can spread or self-replicate from one computer to another
