Detailed explanation-1: -Worms. Similar to a virus, a worm can also self-replicate and spread full copies and segments of itself via network connections, email attachments, and instant messages. Unlike viruses, however, a worm does not require a host program in order to run, self-replicate, and propagate.
Detailed explanation-2: -What is a worm? Worms are programs that replicate themselves from system to system without the use of a host file. This is in contrast to viruses, which requires the spreading of an infected host file.
Detailed explanation-3: -A worm is a standalone program that replicates itself to infect other computers without requiring action from anyone. Since they can spread fast, worms are often used to execute a payload-a piece of code created to damage a system.
Detailed explanation-4: -A worm is a standalone piece of malicious software that reproduces itself and spreads from computer to computer. A virus is a piece of computer code that inserts itself within the code of another standalone program, then forces that program to take malicious action and spread itself.
