Shortly about cryptocurrency mining
Cryptocurrency mining means the action of calculating the transaction block hash. That is a integral part of any project based on the blockchain technology. Since this operation takes a lot of calculations, a strong computer is required. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptomining farms usually consist of tens and hundreds of graphic cards to complete their task efficiently. Such systems are not usable for “usual” purposes, like gaming or browsing the Web. Crooks who gain money via this coin miner use someones’ hardware instead, even if they are used for the regular activity.2

All these changes shall be thrown back to the original in the process of computer recovery.
Hardware effects of coin miner activity
Besides slowing down your computer, running at peak power for a long period of time may trigger damage to your machine and increase power expenses. Hardware components are designed to easily get along with high load, but they can do so only when they are in a good shape.
Tiny and well-protected CPU fan is not very easy to damage. Meanwhile, GPUs have big and easy-to-access rotors, which can be easily broke if affected while running, for instance, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the extremely high load caused by Esif_uf.exe virus can easily lead to graphic processing unit failure3. Video cards are also tend to have very fast wearing when used for crypto mining. It is surely an undesirable situation when the performance of your GPU plunges 20-30% only after 1-2 weeks of being used in such a way.
How did I get Esif_uf.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 widespread malevolent programs among “serious” malware. Adware sometimes acts as a carrier for Esif_uf.exe malware injection: it shows you the banners, which have a link to malware downloading. Sure, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. However, the statistics say that about 30% of all malware spread through the malicious banners are coin miners – and Esif_uf.exe is right one of 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 untrustworthy site as a part of a program. People that spread hacked versions of favored programs (which do not need the license key) have small chances to get paid. Hence, there is a huge temptation to include malware to the final package of the hacked application and receive a coin for every installation. Prior to blaming these people for hacking and also malware distribution, ask yourself – is it okay to avoid paying for the program in such a way? It is much cheaper to pay $20-$30 at once than to pay a much greater figure for antivirus program and new parts for your desktop.
