Understanding Malware

The video tutorial provides an in-depth look at malware, a broad term for software that harms systems. It covers various types of malware, such as viruses, worms, ransomware, and trojan horses, explaining how they operate and propagate. The tutorial emphasizes the importance of data, which is often targeted by attackers due to its value. It also discusses ransomware, a type of malware that encrypts data and demands payment for decryption. The video concludes with prevention strategies, highlighting the need for regular updates, backups, and antivirus software to protect against malware threats.
