What is Dll.exe process?

As I have actually mentioned earlier, Dll.exe is a coin miner trojan. The names of the executive file can be diverse, however, the impacts are generally the same. Considering that coin miners aim at cryptocurrency mining, they use all available hardware power of your personal computer to conduct this process. This malware does not take note of the fact that you may want to use your system for other tasks – it will always consume over 80% of your CPU power.
Dll.exe – Very high CPU/GPU usage
Besides CPU usage, some of the coin miners also use GPU power for their tasks. In that situation, you will likely struggle even to see the mouse arrow moving – GPU is often used on 100%. It is not as critical as CPU for system work, so Dll.exe coin miner viruses don’t waste time on trifles and utilize it all. It often may cause sad consequences.
Shortly about cryptocurrency mining
Crypto mining term means the action of calculating the transaction block hash. That is a integral part of anything based on the blockchain technology. Since this operation takes a lot of calculations, a very strong computer is needed. Exactly, the video card is better for this task, because they have more cores available. Cryptomining farms are usually constructed 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 gain money via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

“Visible” damage is not a single unpleasant thing coin miners perform to your PC. Dll.exe coin miner likewise deals damage to your operating system. To carry out all malevolent operations successfully, it ruins the security components of your system. You will likely see your Microsoft Defender disabled – malware stops it to avoid detection. If you open the HOSTS file, you will likely see a load of new entries – they are added by this coin miner to connect your system to a malicious mining network. All these changes are about to be reverted to the original in the process of PC recovery.
Hardware effects of coin miner activity
Besides slowing down your computer, performing at peak level for a long period of time may trigger damage to your device and increase electricity bills. Hardware elements 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 fan is quite hard to damage. Meanwhile, graphic cards have big and easy-to-access fans, which can be easily broke if touched while spinning, for example, by the user much earlier before the virus injection. Malfunctioning cooling system, together with the extremely high load caused by Dll.exe can easily lead to GPU failure3. Graphic cards are also tend to have fast wearing when utilized for crypto mining. It is surely an undesirable case when the performance of your graphic card decreases on 20-30% just after several weeks of being used in such a way.
How did I get Dll.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 “major” malware. Adware sometimes serves as a carrier for Dll.exe malware infiltration: it demonstrates you the banners, which include a link to malware downloading. Yes, this abstract “malware” can belong to any kind – yet 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 Dll.exe is just one of them.4
The example of malicious banners you can see in the Internet
An additional way you could get this item on your PC is by downloading it from the unreliable site as a part of a program. Users that spread hacked versions of popular programs (which do not demand the license key) have small chances to make money. Therefore, there is a very big temptation to add malware to the final package of the hacked app and get a coin for each setup. Before criticizing these individuals for hacking and also malware spreading, ask yourself – is it okay to avoid purchasing the program in such a way? It is much cheaper to pay $20-$30 one time than to pay a much greater sum for antivirus software and new parts for your PC.
How to remove the Dll.exe miner from my PC?
