Hidmonitorsvc.exe Virus (Coin Miner Trojan) Removal

Hidmonitorsvc.exe executable file belongs to a harmful program that can accurately be recognized as a coin miner virus. That malware form uses your hardware to mine cryptocurrencies, primarily – Monero or DarkCoin1. It makes your system pretty much nonfunctional because of high CPU utilization.

What is Hidmonitorsvc.exe process?

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

As I have actually pointed out in the previous paragraph, Hidmonitorsvc.exe is a coin miner trojan. The names of the .exe file may be diverse, however, the impacts are generally the identical. Because coin miners aim at cryptocurrency mining, they use all available hardware power of your desktop to run this procedure. This malware does not pay attention to the fact that you may want to make use of your machine for other tasks – it will consistently consume over 80% of your processor power.

Hidmonitorsvc.exe – Extremely high CPU/GPU usage

Besides CPU usage, some of the coin miners also use 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 important as processor for system work, so Hidmonitorsvc.exe coin miner viruses do not waste time on trifles and use it all. It often may cause bad results.

Shortly about cryptocurrency mining

Cryptocurrency mining is a term that means the action of calculating the transaction block hash. That is a basic element of any project based on the blockchain technology. Since this action takes a lot of calculations, a very powerful machine is needed. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptomining farms usually consist of dozens of graphic cards to complete their task efficiently. Such computer systems are not usable for “normal” purposes, like gaming or browsing the Web. Crooks 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
  • How dangerous is the Hidmonitorsvc.exe miner?

    Coin miners does not deal damage to your files. However, they make a lot of unpleasant things with the whole system

    Firstly, Hidmonitorsvc.exe malware makes your PC overloaded. It is not able to run your applications now, since all CPU power is consumed by a virus. That malware does not care for your wants, all it focuses on is generating income on you. Even if you are patient, and you waited until web browser is open, you will likely suffer from extremely slow performance. Pages can open for years, any kind of logins will likely take about a minute – just a headache for a person who does a job online.

    “Visible” harm is not a single bad thing coin miners perform to your system. Hidmonitorsvc.exe coin miner also deals damage to your operating system. To complete all malevolent functions successfully, it ruins the protection features of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent recognition. 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 PC to a malicious cryptomining network. All these changes are about to be thrown 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 long times can cause damage to your machine as well as increase power bills. Hardware components are created to easily deal with high load, but they can do so only in case when they are in a good shape.

    Small and well-protected CPU cooling system is not very easy to damage. Meanwhile, GPUs have large and easy-to-access fans, which can be easily cracked if affected while spinning, for example, by the user much before the virus injection. Malfunctioning cooling system, together with the very high load caused by Hidmonitorsvc.exe miner can easily lead to GPU failure3. GPUs are also tend to have very fast wearing when utilized for crypto mining. It is surely an undesirable 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 Hidmonitorsvc.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 widespread malicious programs among “severe” viruses. Adware sometimes works as a carrier for Hidmonitorsvc.exe malware infiltration: it demonstrates you the banners, which include a link to malware downloading. Sure, this abstract “malware” may belong to any type – an additional adware, spyware, rogue or backdoor. However, the statistics show that approximately 30% of all viruses spread with the malevolent banners are coin miners – and Hidmonitorsvc.exe is right one of them.

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    One more way you could get this item on your PC is by downloading it from the untrustworthy website as a part of a program. People that spread hacked versions of well-known programs (which do not require the license key) have small chances to make money. For this reason, there is a huge lure to add in malware to the final package of the hacked application and acquire a coin for each setup. Before criticizing these guys for hacking and malware spreading, ask yourself – is it alright to avoid paying for the program in this manner? It is much cheaper to pay $20-$30 at once than to pay a much greater figure for antivirus program and new parts for your computer.

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

    windows safe mode boot option with command prompt

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