FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A virus is a type of malware that, when executed, self-replicates by modifying other computer programs and inserting their own code. When this replication succeeds, the affected areas are then said to be infected. Virus writers use social engineering and exploit vulnerabilities to infect systems and spread the virus.

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 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-4: -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-5: -Worms. One of the most common types of malware, worms, spread over computer networks by exploiting operating system vulnerabilities. A worm is a standalone program that replicates itself to infect other computers without requiring action from anyone.
