Besides CPU utilization, some of the coin miners also utilize GPU power for their operations. In that case, you will probably struggle even to see the mouse cursor moving – GPU is often utilized on 100%.

Shortly about cryptocurrency mining
Crypto mining means the operation of calculating the transaction block hash. That is a integral element of anything based on the blockchain technology. Since this operation takes a lot of calculations, a very powerful PC is needed. Exactly, the GPU is better for this task, because they have more cores available. Cryptomining farms are usually constructed of dozens of graphic cards to conduct their activity effectively. Such computer systems are not usable for “classic” purposes, like gaming or browsing the Web. Crooks who make profit via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

All these adjustments shall be reverted to the original in the process of system recovery.
Hardware effects of coin miner activity
Besides making your PC slow, performing at peak level for a long period of time can cause damage to your device and raise electricity costs. Hardware components are created to easily get along with high load, but they are good with it only when they are in a good shape.
Compact and covered processor fan is quite hard to damage. Meanwhile, GPUs have big and easy-to-access fans, which can be easily cracked if affected while running, for instance, by the user much earlier before the virus injection. Malfunctioning cooling system, together with the extremely high load caused by Diihost.exe can easily lead to graphic card failure3. Graphic cards are also tend to have increased wearing when used for cryptocurrency mining. It is surely an unwanted situation when your GPU’s performance plunges 20-30% only after several weeks of being exploited in such a way.
How did I get Diihost.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 the most common malevolent programs through “major” viruses. Adware frequently acts as a carrier for Diihost.exe malware infiltration: it shows you the banners, which have a link to malware downloading. Yes, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. However, the statistics show that approximately 30% of all malware spread with the malicious banners are coin miners – and Diihost.exe is just one of them.4
The example of malicious banners you can see in the Internet
One more way you could get this thing on your PC is by downloading it from the unreliable website as a part of a program. Users that spread hacked versions of well-known programs (which do not require the license key) have small chances to earn money. For this reason, there is a huge lure to include malware to the final package of the hacked app and acquire a coin for each setup. Prior to criticizing these individuals for hacking and also malware distribution, ask yourself – is it okay to avoid purchasing the program in this manner? It is more affordable to pay $20-$30 one time than to pay a much greater figure for antivirus software and new parts for your desktop.
