Detailed explanation-1: -Computer worms are among the most common types of malware. They spread over computer networks by exploiting operating system vulnerabilities. Worms typically cause harm to their host networks by consuming bandwidth and overloading web servers. Computer worms can also contain “payloads” that damage host computers.
Detailed explanation-2: -A computer worm duplicates itself to spread to uninfected computers. It often does this by exploiting parts of an operating system that are automatic and invisible to the user. Typically, a user only notices a worm when its uncontrolled replication consumes system resources and slows or halts other tasks.
Detailed explanation-3: -How do viruses and worms spread? As mentioned above, viruses require human interaction, such as you executing an infected program, to spread. Worms can spread automatically, without you doing anything.
