Mcsvhost.exe executable file is related to a malicious application that can correctly be defined as a coin miner virus. That malware form utilizes your PC components to mine cryptocurrencies, basically – Monero or DarkCoin1. It makes your system roughly unusable due to high CPU use.
What is Mcsvhost.exe process?
Mcsvhost.exe is a malicious process created by coin miner virus
As I have pointed out previously, Mcsvhost.exe is a coin miner trojan virus. The names of the .exe file can be diverse, but the effects are almost always the identical. Because coin miners aim at cryptocurrency mining, they use all possible hardware capacity of your PC to conduct this process. This malware doesn’t take note of the fact that you probably want to use your desktop for other activities – it will always use over 80% of your processor power.
Mcsvhost.exe – Really high CPU and GPU use
Besides CPU consumption, some of the coin miners also use GPU power for their operations. In that situation, you will struggle also to see the mouse cursor moving – GPU is often used on 100%. It is not as vital as processor for system work, so Mcsvhost.exe coin miner viruses do not waste time on trifles and use it all. It often can lead to sad effects.
Shortly about cryptocurrency mining
Crypto mining means the action of calculating the transaction block hash. That is a integral element of any project based on the blockchain technology. Since this action takes a lot of calculations, a high-end desktop is required. Exactly, the graphic card is better for this task, because they have more cores available. Cryptocurrency mining farms are usually constructed of dozens of graphic cards to complete their task efficiently. Such computer systems are not usable for “usual” purposes, like gaming or browsing the Web. Crooks 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 bad activity coin miners do to your computer. Mcsvhost.exe coin miner also deals damage to your OS. To execute all malicious operations effectively, it ruins the protection features of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent detection. If you check the HOSTS file, you will likely see a load of new notes – they are added by this trojan miner to connect your computer to a malicious cryptomining network. All these changes shall be gone back to the original in the process of system recovery.
Hardware effects of coin miner activity
Besides making your computer slow, running at peak power for a long period of time can cause damage to your device as well as raise electricity costs. PC components are created to easily deal with high load, but they are good with it only when they are in a good shape.
Tiny and well-protected CPU cooling system is hard to crack. Meanwhile, graphic cards have large and easy-to-access rotors, which can be easily broke if touched while running, for instance, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the extremely high load caused by Mcsvhost.exe miner can easily lead to graphic processing unit failure3. GPUs are also tend to have increased wearing when used for cryptocurrency mining. It is surely an unwanted situation when your GPU’s performance decreases on 20-30% just after several weeks of being used in such a way.
How did I get Mcsvhost.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 among “serious” viruses. Adware frequently serves as a carrier for Mcsvhost.exe malware infiltration: it demonstrates you the banners, which include a link to malware downloading. Sure, this abstract “malware” may belong to any kind – yet another adware, spyware, rogue or backdoor. But the statistics say that around 30% of all viruses spread with the malevolent banners are coin miners – and Mcsvhost.exe is right with them.4
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 dubious site as a part of a program. Users that spread hacked versions of favored programs (which do not demand the license key) have small chances to earn money. Therefore, there is a huge temptation to include malware to the final package of the hacked application and acquire a coin for every installation. Before blaming these individuals for hacking and malware distribution, ask yourself – is it okay to avoid paying for the program in this manner? It is more affordable to pay $20-$30 at once than to pay a much greater sum for antivirus program as well as new parts for your desktop.
How to remove the Mcsvhost.exe miner from my PC?
The best way to get rid of this coin miner virus is to use anti-malware software
Eliminating such a virus needs using specific program. Appropriate security tool must have high efficiency at scanning and also be lightweight – in order to make no problems with usage also on weak systems. Furthermore, it is recommended to have proactive security in your protection tool – to stop the virus even before it starts. Microsoft Defender lacks these features for different reasons. That’s why I’d recommend you to use a third-party anti-malware program for that objective. GridinSoft Anti-Malware is a superb choice that fits each of the discussed qualities.5
Prior to the virus removal, it is important to boot your Windows into Safe Mode with Networking. Since Mcsvhost.exe miner takes a lot of CPU capacity, it is required to halt it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.
Booting the PC into Safe Mode with Networking
Press the Start button, then choose Power, and click on Reboot while holding the Shift key on the keyboard.

When your computer is in Safe Mode, all third-party applications, just like the majority of non-crucial Windows components, are not launched with the system start. That allows you to clean the system without dealing with high CPU usage of the coin miner.
