Detailed explanation-1: -A computer worm is a type of malware whose primary function is to self-replicate and infect other computers while remaining active on infected systems. A computer worm duplicates itself to spread to uninfected computers.
Detailed explanation-2: -A Worm is a self-replicating program. It is self-contained and does not require a host program. The program creates the copy and causes it to execute; no user intervention is required. Worms commonly utilize network services to propagate to other computer systems [19].
Detailed explanation-3: -A virus is a computer program that replicates itself by modifying system or application software and then traveling from computer to computer, via disks or a network.
Detailed explanation-4: -A virus is the most common type of malware that can execute itself and spread by infecting other programs or files. A worm can self-replicate without a host program and typically spreads without any interaction from the malware authors.
Detailed explanation-5: -Worms are a self-replicating type of malware (and a type of virus) that enter networks by exploiting vulnerabilities, moving quickly from one computer to another. Because of this, worms can propagate themselves and spread very quickly – not only locally, but have the potential to disrupt systems worldwide.
