Explanation A cryptominer is a malicious program that uses the CPU resources of a computer to generate cryptocurrency, such as Bitcoin or Ethereum. This can cause the CPU to run at 100% utilization and slow down the system. Spyware, virus and keylogger are other types of malware, but they do not necessarily cause high CPU usage.
