After installing a third-party program, a user notices that the fan on their computer constantly spins. A technician reviews Task Manager and identifies several processes that are utilizing significant CPU load. Which of the following is most likely running on this device?

Stalkerware is software that monitors a user's activities, often without their consent. While it can consume resources, it typically does not engage the CPU to the same extent as cryptominers do. Its primary function is surveillance, not intensive processing, making it less likely to cause the observed symptoms.

Spyware is designed to gather information from a user's device covertly. While it may use some CPU resources, it generally operates in the background without significantly impacting performance. The symptoms of constant fan spinning and high CPU usage are more characteristic of processes that require substantial computational power, such as cryptominers.

Keyloggers record keystrokes to capture sensitive information. Although they run in the background, they typically do not demand high CPU resources, resulting in limited impact on system performance. This makes them an unlikely cause of the observed high CPU load and constant fan activity.
