FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Types of malware include the following: 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-2: -File infector viruses: these infect program files, such as applications, games or utilities. They are often memory-resident, meaning that once they have been executed they remain active in the computer’s memory and can infect more programs.

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: -Computer Viruses Computer viruses are a type of malware that earned their name because of how they spread by “infecting” other files on a disk or computer.

Detailed explanation-5: -Viruses are computer programs that connect to other software or programs to harm the system, whereas worms duplicate themselves to slow down the computer system. On the other hand, rather than replicating, a Trojan horse stores critical data about a computer system or a network.
