A computer virus is a program that is installed without the permission or knowledge of the computer user.
It is designed to alter the computer's normal operations and can replicate itself to infect other files, programs, or media it can access. Computer viruses are malicious and often spread through infected files, emails, or downloads.
Once inside a computer system, they can cause various damages, such as corrupting data, stealing personal information, or disrupting the computer's functionality.
As they replicate, they can rapidly spread to other devices and networks, making them a significant threat to the security and integrity of computer systems worldwide.
Protecting against viruses requires robust antivirus software and cautious online behavior.

Answer: black-box testing
The advantage of black-box testing in computer science is its simplicity and the freedom from assumptions about expected input to any function or program. It tests functionality of an application without considering the internal mechanism.
The major advantage of black-box testing is its simplicity and its freedom from assumptions about the expected input to any program, service, or function. In computer science, black-box testing is a method of software testing where the functionality of an application is examined without considering the internal mechanism or architecture. Essentially, the tester does not need to know how the system or component is implemented. They only need to understand the input and the expected output. This methodology holds an advantage in its simplicity and its liberation from assumptions about the expected input to any function, system, or program.
