Detailed explanation-1: -A computer virus is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code into those programs. If this replication succeeds, the affected areas are then said to be “infected” with a computer virus, a metaphor derived from biological viruses.
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 computer virus is a type of malware that attaches to another program (like a document), which can replicate and spread after a person first runs it on their system. For instance, you could receive an email with a malicious attachment, open the file unknowingly, and then the computer virus runs on your computer.
Detailed explanation-4: -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. Most viruses are harmless, but some viruses can erase files on your hard drive, slow down your computer, or do other kinds of damage.
Detailed explanation-5: -A worm is a self-replicating program that is harmful to networks. A worm uses the network to duplicate its code to the hosts on a network, often without any user intervention.
