Practical Cyber Hacking Skills for Beginners - Malware Revisited

The video tutorial provides an overview of various types of malware, including viruses, worms, Trojans, rootkits, spyware, adware, keyloggers, and ransomware. It explains the characteristics, limitations, and dangers of each type. Viruses require activation by the host, while worms can spread through networks. Trojans are deceptive but cannot self-replicate. Rootkits are hard to detect and remove, often requiring a complete system wipe. Spyware and adware monitor user activities, and keyloggers record keystrokes. Ransomware is introduced as a topic for the next video.
