Understanding Malware and Its Types

The video tutorial introduces malware, explaining its types and characteristics. It begins with a discussion on software and its execution, followed by a detailed explanation of malware as malicious software. The tutorial covers different types of malware, including viruses, worms, and Trojan horses, highlighting their unique features and methods of spreading. Viruses replicate by inserting themselves into host programs, while worms can spread independently across networks. Trojan horses disguise themselves as legitimate software but contain harmful code, often providing backdoor access to attackers.
