Shortly about cryptocurrency mining
Cryptocurrency mining term means the action of calculating the transaction block hash. That is a basic part of any project based on the blockchain technology. Since this operation takes a lot of calculations, a very strong machine is needed. Exactly, the graphic card is better for this task, because they have more cores available. Cryptocurrency mining farms are usually constructed of tens and hundreds of video cards to complete their task efficiently.

All these adjustments shall be gone back to the original in the process of system recovery.
Hardware effects of coin miner activity
Besides making your computer slow, performing at peak level for a long period of time may cause damage to your device and raise power costs. Hardware elements are designed to easily deal with high load, but they are good with it only when they are in a good shape.
Tiny and covered processor fan is hard to damage. Meanwhile, GPUs have large and easy-to-access rotors, which can be easily cracked if affected while running, for example, by the user much earlier before the coin-miner injection. Malfunctioning cooling system, together with the really high load caused by Fesa.exe malware can easily lead to graphic processing unit failure3. Graphic cards are also prone to have very fast wearing when used for crypto mining. It is surely an unwanted situation when your GPU’s performance plunges 20-30% only after 1-2 weeks of being used in such a way.
How did I get Fesa.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 “serious” viruses. Adware sometimes works as a carrier for Fesa.exe malware injection: it shows you the banners, which include a link to malware downloading. Yes, this abstract “malware” may belong to any type – yet another adware, spyware, rogue or backdoor. However, the statistics show that approximately 30% of all viruses spread through the malicious banners are coin miners – and Fesa.exe is just one of them.
The example of malicious banners you can see in the Internet
Another way you could get this thing on your computer is by downloading it from the untrustworthy web page as a part of a program. People who spread hacked variants of popular programs (which do not demand the license key) have small chances to earn money. Hence, there is a huge temptation to add in malware to the final package of the hacked app and acquire a coin for every installation. Prior to criticizing these people for hacking and also malware distribution, ask yourself – is it OK to avoid purchasing the program in such a way? It is much cheaper to pay $20-$30 one time than to pay a much bigger sum for antivirus software as well as new parts for your desktop.
