Answer:
The computer must be infected with malicious virus.
Explanation:
Since Kyle did a troubleshooting of the client’s computer by running Disk Defragmenter and Disk Clean-up utilities and found out, that the CPU was running several processes in the Windows task manager.
After restarting the computer, he noticed a long load time for Windows and saw several processes that he did not recognize.
This is obviously a sign of an infected system by a malicious virus.
Kyle should install an antivirus program such as Avast or Kaspersky on the computer and run a deep virus scan to detect any virus.
