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.

Turning off the machine is the first and most urgent step to prevent further damage to the host and other systems. Ransomware can encrypt files, steal data, and spread to other devices on the network if the infected machine remains online. Turning off the machine will stop the ransomware process and isolate the machine from the network12. The other options are either ineffective or risky. Running a full antivirus scan may not detect or remove the ransomware, especially if it is a new or unknown variant. Removing the LAN card may disconnect the machine from the network, but it will not stop the ransomware from encrypting or deleting files on the local drive. Installing a different endpoint solution may not be possible or helpful if the ransomware has already compromised the system or blocked the installation.

Disk Defragment is a tool that can be used to improve the performance of a hard disk drive (HDD). HDDs store data in sectors and clusters on spinning platters. Over time, as data is written, deleted, and moved, the data may become fragmented, meaning that it is spread across different locations on the disk. This causes the HDD to take longer to access and load data, resulting in slower performance. Disk Defragment consolidates the fragmented data and rearranges it in a contiguous manner, which reduces the seek time and increases the speed of the HDD. Disk Management, Disk Cleanup, and Device Manager are not tools that can alleviate the issue of slow HDD performance.
