Answer:
A computer virus is a malicious software program loaded onto a user’s computer without the user’s knowledge and performs malicious actions.
Viruses which are the most commonly-known form of malware and potentially the most destructive. A virus can do anything from erasing the data on a computer to hijacking a computer to attack other systems, send spam, or host and share illegal content.
Explanation:
The term 'computer virus' was first formally defined by Fred Cohen in 1983. Computer viruses never occur naturally because they are always induced by people. Once created and released, however, their diffusion is not directly under human control. After entering a computer, a virus attaches itself to another program in such a way that execution of the host program triggers the action of the virus simultaneously. It can self-replicate, inserting itself onto other programs or files, infecting them in the process. Not all computer viruses are destructive though. However, most of them perform actions that are malicious in nature, such as destroying data. Some viruses wreak havoc as soon as their code is executed, while others lie dormant until a particular event (as programmed) gets initiated, that causes their code to run in the computer. Viruses spread when the software or documents they get attached to are transferred from one computer to another using a network, a disk, file sharing methods, or through infected email attachments. Some viruses use different stealth strategies to avoid their detection from anti-virus software. Some old viruses make sure that the "last modified" date of a host file stays the same when they infect the file.

difference between boot disk and booting in 5 points
In computing, booting is the process of starting a computer. It can be initiated by hardware such as a button press, or by a software command. After it is switched on, a computer's central processing unit (CPU) has no software in its main memory, so some process must load software into memory before it can be executed. This may be done by hardware or firmware in the CPU, or by a separate processor in the computer system.
A boot disk is a removable digital data storage medium from which a computer can load and run an operating system or utility program. The computer must have a built-in program which will load and execute a program from a boot disk meeting certain standards.
The software which manages environment for running programs handling error controlling devices configuring the computer system and managing the resources of a computer.
