Shortly about cryptocurrency mining
Crypto mining means the action of calculating the transaction block hash. That is a basic part of anything based on the blockchain technology. Since this action takes a lot of calculations, a very powerful computer is required. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptocurrency mining farms usually consist of tens and hundreds of graphic cards to conduct their activity effectively. Such computer systems are not usable for “normal” purposes, like gaming or browsing the Web. Fraudsters who make profit via this coin miner use someones’ hardware instead, even if they are used for the regular activity.2

Besides decreasing your system’s performance, performing at peak power for long times can trigger damage to your machine and increase power expenses. Hardware components are designed to easily get along with high load, but they are good with it only in case when they are in a good shape.
Tiny and covered CPU cooling system is hard to broke.

How did I get \”fish.exe coin miner virus?
Coin miners are spread through different ways, but their main sources are malicious banners and programs from dubious sources
Coin miners are one of the most prevalent malevolent programs through “severe” viruses. Adware frequently acts as a carrier for \”fish.exe malware injection: it demonstrates you the banners, which have a link to malware downloading. Sure, this abstract “malware” may belong to any kind – yet another adware, spyware, rogue or backdoor. But the statistics show that approximately 30% of all malware spread through the malevolent banners are coin miners – and \”fish.exe is right among them.4
The example of malicious banners you can see in the Internet
Another way you could get this item on your PC is by downloading it from the dubious site as a part of a program. Users who spread hacked variants of favored programs (which do not demand the license key) have small chances to earn money. Thus, there is a huge temptation to include malware to the final package of the hacked app and receive a coin for every installation. Before criticizing these people for hacking and also malware spreading, ask yourself – is it OK to avoid paying for the program in such a way? It is more affordable to pay $20-$30 one time than to pay a much greater sum for antivirus program as well as new parts for your PC.
