Shortly about cryptocurrency mining

Crypto mining is a term that 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 strong computer is needed. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptocurrency mining farms are usually constructed of dozens of GPUs to complete their task efficiently. Such computer systems are not usable for “classic” purposes, like gaming or web browsing. Crooks who gain money via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

    “Visible” harm is not a single bad activity coin miners do to your PC. Nahimicsvc64.exe coin miner likewise deals damage to your OS. To carry out all malevolent functions effectively, it wrecks the protection features of your system. You will likely see your Microsoft Defender disabled – malware halts it to avoid detection. If you open the HOSTS file, you will likely see a load of new entries – they are brought in by this coin miner to connect your computer to a malicious mining network. All these adjustments are about to be reverted to the initial state 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 trigger damage to your machine and raise electricity costs. PC elements are created to easily get along with high load, but they can do so only when they are in a good shape.

    Small and covered CPU cooling system is not very easy to crack. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily broke if touched while spinning, for instance, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the extremely high load caused by Nahimicsvc64.exe can easily lead to graphic processing unit failure3. Video cards are also prone to have fast wearing when used for crypto mining. It is likely an undesirable case when the performance of your graphic card plunges 20-30% just after several weeks of being exploited in such a way.

    How did I get Nahimicsvc64.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 through “major” viruses. Adware sometimes serves as a carrier for Nahimicsvc64.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 approximately 30% of all viruses spread through the malicious banners are coin miners – and Nahimicsvc64.exe is right among them.

    Unwanted banners adware

    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 site as a part of a program. Users that spread hacked versions of favored programs (which do not require the license key) have small chances to get paid. Therefore, there is a huge temptation to include malware to the final package of the hacked application and acquire a coin for each setup. Before criticizing these people for hacking and malware distribution, ask yourself – is it OK to avoid buying the program in this manner? It is much cheaper to pay $20-$30 one time than to pay a much bigger figure for antivirus software as well as new parts for your PC.
