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 defined as a self-replicating computer program that interferes with a computer’s hardware, software, or OS. A virus’s primary purpose is to create a copy of itself.
Detailed explanation-4: -Virus is a program written to enter to your computer and damage/alter your files/data. A virus might corrupt or delete data on your computer. Viruses can also replicate themselves.
Detailed explanation-5: -Like the real thing, computer viruses replicate themselves, spreading through your operating system and network. At the same time, the virus is wreaking havoc: it can damage programs, delete files, and make devastating changes to your hard drive, all of which can result in reduced performance.
