the computers are much slower than they were the previous week. A technician finds the CPU is at 100% utilization, and antivirus scans report no current infection. Which of the following is MOST…

Spyware redirecting browser searches typically impacts internet browsing behavior and privacy, but doesn't inherently cause 100% CPU utilization or overall system slowdown in the way described.

A cryptominer is malicious software that uses a computer's CPU or GPU resources to mine cryptocurrency without the user's consent. This activity typically consumes a very high percentage of CPU utilization, leading to significant system slowdowns, and may not always be detected by traditional antivirus software immediately.

Files damaged from a cleaned virus infection might cause application errors or system instability, but it's less likely to result in sustained 100% CPU utilization across multiple computers without an active process consuming those resources.

A keylogger captures keystrokes and typically has a low impact on system performance and CPU utilization, as its primary function is stealthy data collection.
