Which warning indicates that a computer might be infected with a virus?

• A. Fast boot time
• B. Slow performance and unusual pop-ups
• C. Reduced screen brightness
• D. Frequent software updates

Answer: (B)

A slow performance combined with unusual pop-ups is a common warning sign that a computer might be infected with a virus. When malware or viruses are present on a computer, they often consume system resources, leading to sluggish performance. Additionally, many types of malware generate pop-up ads or messages as part of their activity or when they attempt to lure users into unwittingly downloading more malicious software. This combination of symptoms is indicative of possible infection and should prompt users to take further action, such as running a virus scan or seeking technical assistance to diagnose and resolve the issue. The other options do not typically indicate a virus infection. For instance, fast boot times are generally seen as a positive performance trait, and reduced screen brightness can relate to hardware settings rather than malware. Frequent software updates can actually be beneficial, as they often include security patches to protect against vulnerabilities, rather than being a sign of infection.
