What are the different types of malware?

• Worms: A worm is basically a type of malicious malware that spreads rapidly from one computer to another via email and file sharing. Worms do not require host software or code to execute.
  
  
• Spyware: Spyware is basically a type of malicious malware that runs in the background of your computer, steals all your sensitive data, and reports this data to remote attackers.
  
  
• Ransomware: Ransomware is used as malware to extort money from users for ransom by gaining unauthorized access to sensitive user information and demanding payment to delete or return that information from the user.
  
  
• Virus: A virus is a type of malicious malware that comes as an attachment with a file or program. Viruses usually spread from one program to another program, and they will run only when the host file gets executed. The virus can only cause damage to the computer until the host file runs.
  
  
• Trojan: Trojans are malicious, non-replicating malware that often degrades computer performance and efficiency. Trojans have the ability to leak sensitive user information and modify and delete this data.
  
  
• Adware: Adware is another type of malware that tracks the usage of various types of programs and files on your computer and displays personalized ad recommendations based on your usage history.
