Which of the following is a sign that spyware may be present on your system?

Frequent pop-up ads are a strong indicator that spyware may be present on your system. Spyware often generates unwanted advertisements, which can manifest as numerous pop-ups while you’re browsing the internet. These ads typically appear unexpectedly and can be intrusive, disrupting your online experience. In many cases, spyware collects data without your consent and can lead to a barrage of advertisements tailored based on your browsing habits, indicating its presence.

On the other hand, increased battery life, smooth internet browsing, and faster download speeds are not signs of spyware. Increased battery life suggests that your system is running efficiently, which is generally not affected by the presence of spyware. Smooth internet browsing and faster download speeds often indicate that your system is optimized and free from malicious software, making these choices unrelated to spyware detection.
