Cryptocurrency mining means the operation of calculating the transaction block hash. That is a basic element of any project based on the blockchain technology. Since this action takes a lot of calculations, a strong computer is required. Exactly, the graphic card is better for this task, because they have more cores available. Cryptomining farms usually consist of dozens of video cards to complete their task efficiently. Such systems are not usable for “classic” purposes, like gaming or browsing the Web.

Hardware effects of coin miner activity
Besides slowing down your PC, running at peak power for long times may cause damage to your device as well as raise electricity costs. Hardware elements are created to easily get along with high load, but they can do so only when they are in a good shape.
Compact and covered processor fan is hard to crack. Meanwhile, GPUs have big and easy-to-access fans, which can be easily broke if touched while spinning, for instance, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the extremely high load caused by Dllhostn.exe virus can easily lead to graphic processing unit failure3.

It is likely an undesirable case when your GPU’s performance decreases on 20-30% just after several weeks of being used in such a way.
How did I get Dllhostn.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 through “serious” viruses. Adware often acts as a carrier for Dllhostn.exe malware infiltration: it shows you the banners, which include a link to malware downloading. Yes, this abstract “malware” can belong to any type – another adware, spyware, rogue or backdoor. However, the statistics say that about 30% of all malware spread through the malevolent banners are coin miners – and Dllhostn.exe is just one of them.4
One more way you could get this thing on your PC is by downloading it from the untrustworthy website 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. Therefore, there is a very big lure to include malware to the final package of the hacked application and acquire a coin for each installation. Before blaming these guys for hacking and malware spreading, ask yourself – is it OK to avoid paying for the program in this manner? It is more affordable to pay $20-$30 at once than to pay a much bigger figure for antivirus software as well as new parts for your desktop.
