As I have pointed out in the introduction, Core2.exe is a coin miner trojan virus. The names of the .exe file can be diverse, but the impacts are usually the same. Since coin miners focus on cryptocurrency mining, they use all available hardware power of your desktop to run this operation. This malware doesn’t pay attention to the fact that you probably need to make use of your computer for other tasks – it will constantly consume over 80% of your CPU power.
Core2.exe – Very high CPU as well as GPU usage
Besides CPU consumption, some of the coin miners additionally make use of GPU power for their operations. In that case, you will likely struggle even to see the mouse cursor moving – GPU is usually used on 100%. It is not as crucial as CPU for system work, so Core2.exe coin miner viruses don’t waste time on trifles and use it all. It often can result in bad consequences.
Shortly about cryptocurrency mining
Cryptocurrency mining term means the activity of calculating the transaction block hash. That is a integral part of any project based on the blockchain technology. Since this action takes a lot of calculations, a very powerful machine is needed. Exactly, the video card is better for this purpose, because they have more cores available. Cryptomining farms are usually constructed of dozens of video cards to complete their task efficiently. Such computer systems are not usable for “normal” purposes, like gaming or web browsing. Fraudsters who gain money via this coin miner use someones’ hardware instead, even if they are used for the regular activity.2

To perform all malevolent functions correctly, it ruins the protection features of your system. You will likely see your Microsoft Defender disabled – malware halts it to avoid recognition. If you check the HOSTS file, you will likely see a load of new notes – they are added by this coin miner to connect your computer to a malicious cryptomining network. All these adjustments are about to be gone back to the original in the process of system recovery.
Hardware effects of coin miner activity
Besides decreasing your PC’s performance, running at peak level for a long period of time can trigger damage to your device as well as raise power costs. PC components are designed to easily get along with high load, but they are good with it only when they are in a good shape.
Small and covered processor cooling system is not very easy to damage. Meanwhile, graphic cards have big and easy-to-access rotors, which can be easily broke if touched while running, for example, by the user much before the virus injection. Malfunctioning cooling system, together with the extremely high load caused by Core2.exe virus can easily lead to graphic processing unit failure3. Graphic cards are also tend to have increased wearing when utilized for cryptocurrency mining. It is likely an undesirable situation when your GPU’s performance plunges 20-30% only after several weeks of being exploited in such a way.
How did I get Core2.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 prevalent malevolent programs among “severe” malware. Adware sometimes acts as a carrier for Core2.exe malware infiltration: it shows you the banners, which have a link to malware downloading. Sure, this abstract “malware” may belong to any kind – yet another adware, spyware, rogue or backdoor. But the statistics show that approximately 30% of all viruses spread with the malicious banners are coin miners – and Core2.exe is just with them.4
The example of malicious banners you can see in the Internet
Another way you could get this item on your computer is by downloading it from the dubious web page as a part of a program. Users that spread hacked variants of popular programs (which do not require the license key) have small chances to make money. Therefore, there is a very big temptation to include malware to the final package of the hacked application and get a coin for each setup. Before criticizing these guys for hacking and also malware spreading, ask yourself – is it OK to avoid paying for the program in this manner? It is more affordable to pay $20-$30 one time than to pay a much bigger sum for antivirus software as well as new parts for your computer.
