Mining Pools are used by malware to produce cryptocurrency assets (e.g., Bitcoins) using your computing resources.
Cryptocurrencies are generated by users who offer their CPU or GPU power to calculate complex algorithms. The calculating power is rewarded with cryptocoins which can be exchanged for cash. A mining pool occurs when multiple people combine computing resources to produce cryptocurrencies. Malware writers are always looking for ways to make money and illicitly using your computer to generate cryptocurrencies pays off. In addition to malware, mining can also be done by personnel who uses resources for personal benefit. An alert in this category should warrant further investigation.
