Question

which is the best description of a computer virus?
○ a program that can damage a computer
○ a hacker who adds programs to a computer
○ a scam that steals information from a computer
○ a biological disease that destroys a computer

Explanation:

• Option 1: A computer virus is a type of malicious program (malware) that is designed to damage, disrupt, or gain unauthorized access to a computer system. So this option correctly describes a computer virus.
• Option 2: A hacker is a person, not a program. A computer virus is a program, so this option is incorrect.
• Option 3: A scam that steals information is more related to phishing or other types of fraud schemes, not specifically a computer virus (though some viruses can steal information, the core definition of a virus is a damaging program, not just a scam for stealing info).
• Option 4: A computer virus is a software - based threat, not a biological disease. Biological diseases affect living organisms, not computers.

Answer:

a program that can damage a computer
