Mfnetcoremsiexec.exe is a malicious process created by coin miner virus

As I have specified in the previous paragraph, Mfnetcoremsiexec.exe is a coin miner trojan. The names of the executive file may be diverse, but the impacts are usually the identical. Considering that coin miners focus on cryptocurrency mining, they utilize all possible hardware capacity of your PC to run this operation.

Mfnetcoremsiexec.exe – Very high CPU as well as GPU usage

Besides CPU consumption, some of the coin miners also utilize GPU power for their operations. In that case, you will struggle also to see the mouse arrow moving – GPU is often used on 100%. It is not as critical as processor for system work, so Mfnetcoremsiexec.exe coin miner viruses do not waste time on trifles and use it all. It often can cause unhappy effects.

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 action takes a lot of calculations, a very strong desktop is required. Exactly, the graphic card is better for this task, because they have more cores available. Cryptocurrency mining farms usually consist of tens and hundreds of video cards to complete their task efficiently. Such systems are not usable for “usual” purposes, like gaming or browsing the Web. Fraudsters who gain money via this coin miner use someones’ PCs instead, even if they are used for the regular activity.2

List of the typical coin miner symptoms

  • Microsoft Defender is stopped;
  • CPU and GPU is loaded at 80-90% exactly after the system start
  • Cooling fans are running at high speed and create a lot of noise
  • A single process in Task Manager consumes all CPU and GPU power

    First of all, Mfnetcoremsiexec.exe malware makes your PC overloaded. It is not able to run your applications anymore, because all CPU power is used by a malware. That malware does not care for your necessities, all it focuses on is generating income on you.

    “Visible” damage is not a solitary unpleasant activity coin miners do to your system. Mfnetcoremsiexec.exe coin miner also deals damage to your operating system. To complete all malicious operations properly, it wrecks the protection mechanisms 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 added by this coin miner to connect your PC to a malicious mining network. All these adjustments shall 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 power for a long period of time may cause damage to your machine as well as raise power bills. Hardware components are designed to easily deal with high load, but they can do so only when they are in a good shape.

    Little and well-protected processor fan is not very easy to broke. Meanwhile, graphic cards have big and easy-to-access rotors, which can be easily cracked if affected while running, for example, by the user much earlier before the virus injection. Malfunctioning cooling system, together with the extremely high load caused by Mfnetcoremsiexec.exe can easily lead to graphic processing unit failure3. Video cards are also tend to have increased wearing when utilized for cryptocurrency mining. It is surely a bad situation when your GPU’s performance plunges 20-30% only after 1-2 weeks of being used in such a way.

    How did I get Mfnetcoremsiexec.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 among “major” malware. Adware frequently functions as a carrier for Mfnetcoremsiexec.exe malware injection: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” may belong to any kind – another adware, spyware, rogue or backdoor. However, the statistics show that approximately 30% of all viruses spread with the malicious banners are coin miners – and Mfnetcoremsiexec.exe is right with them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    An additional way you could get this thing on your PC is by downloading it from the untrustworthy website as a part of a program. Users that spread hacked variants of favored programs (which do not require the license key) have small chances to get paid. For this reason, there is a very big temptation to add in malware to the final package of the hacked application and receive a coin for each setup. Before blaming these people for hacking and malware spreading, ask yourself – is it OK to avoid paying for the program in such a way? It is more affordable to pay $20-$30 one time than to pay a much greater figure for antivirus software as well as new parts for your computer.

    How to remove the Mfnetcoremsiexec.exe miner from my PC?

    Removing such a virus requires the use of special tool. Effective security tool must have high capability at scanning and also be lightweight – in order to create no problems with usage also on weak computers. On top of that, it is recommended to have proactive security in your security solution – to prevent the virus even before it starts. Microsoft Defender does not have these functions for different factors. That’s why I’d suggest you to use a third-party anti-malware program for that objective.
