7 Types of Malware Explained in 4 Minutes

Summary

The video introduces malware as a broad term for malicious software, then explains seven common types:

• Virus: Malicious code that attaches to legitimate files and can corrupt them. It is compared to a biological virus attacking healthy cells.
• Worm: Malware that copies itself and spreads through network weaknesses. It can consume system resources, slow devices, or disrupt an entire network.
• Ransomware: Malware that encrypts files or data and demands payment—often in cryptocurrency—in exchange for restoring access.
• Trojan horse: Malware disguised as something harmless or useful. Once installed, it may open a backdoor, steal information, or perform other hidden actions. The video compares this deception to the story of the Trojan Horse.
• Spyware: Software that secretly monitors someone. It may take pictures or make recordings and send them to whoever controls it.
• Keylogger: Software that records keystrokes, potentially exposing what a person types.
• Adware: Software that displays unwanted advertisements, such as persistent pop-ups, sometimes when no other application is open.

Main takeaway: Malware is the umbrella category. Its different types are distinguished by how they spread, conceal themselves, or affect a user’s files, system, or privacy.
