Q. Which one of the following would be considered as a way that a computer virus can enter a computer system?
✅ Correct Answer: (C)
Borrowed copies of software
Explanation:
Viruses often spread through infected software, especially borrowed or pirated copies that may carry malicious code.
Other options:
- (A) Viewing a website without causing any additional transactions: Generally safe; simply viewing a website usually doesn't infect a computer unless there are vulnerabilities exploited.
- (B) Running antivirus programs: This helps prevent infections, not cause them.
- (D) Opening an application previously installed: If the application is safe and clean, it won't infect the system; however, if already infected, it could spread the virus — but the question focuses on entry methods.
So, the best answer is: Borrowed copies of software.
