Which of the following is a sign of a potential malware infection?

• A. Increased internet speed
• B. Unusual pop-ups and slow system performance
• C. Frequent software updates
• D. All applications running smoothly

Answer: (B)

Unusual pop-ups and slow system performance are clear indicators of potential malware infection. Malware often affects system resources, leading to slower performance and causing unwanted advertisements or notifications, which manifest as unusual pop-ups. These symptoms suggest that malicious software may have compromised the system, affecting not only its performance but also the user experience by introducing unwanted and potentially harmful content.

In contrast, increased internet speed is not typically associated with malware infections; rather, it could indicate a normal or improved network performance. Frequent software updates generally reflect good system maintenance and security practices meant to close vulnerabilities but do not indicate malware. Lastly, all applications running smoothly suggests that the system is functioning properly, which would not align with the disruptions caused by malware activity. Therefore, the presence of unusual pop-ups and sluggish performance is the most telling sign of a possible infection.
