What is Drvcmna.exe process?

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

As I have specified before, Drvcmna.exe is a coin miner trojan virus. The names of the executive file can be different, but the consequences are almost always the identical. Considering that coin miners aim at cryptocurrency mining, they utilize all possible hardware power of your desktop to run this operation. This virus doesn’t take note of the fact that you may need to make use of your device for other tasks – it will always use over 80% of your processor power.

Drvcmna.exe – Extremely high CPU as well as GPU usage

Besides CPU usage, some of the coin miners also utilize GPU power for their operations. In that instance, you will struggle also to see the mouse arrow moving – GPU is often used on 100%. It is not as crucial as processor for system work, so Drvcmna.exe coin miner viruses do not waste time on trifles and utilize all of it. It sometimes may lead to sad results.

Shortly about cryptocurrency mining

Cryptocurrency mining is a term that means the operation of calculating the transaction block hash. That is a integral part of anything based on the blockchain technology. Since this action takes a lot of calculations, a very powerful desktop is required. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptocurrency mining farms usually consist of tens and hundreds of graphic cards to conduct their activity effectively. Such computer systems are not usable for “normal” purposes, like gaming or browsing the Web. Fraudsters who gain money via this coin miner use someones’ computers instead, even if they are used for the regular activity.

List of the typical coin miner symptoms

  • Your device overheats (system unit/laptop body is very hot)
  • You are not able to open your apps or they are opening for ages
  • Unknown process is running in the background and consumes your PC resources
  • Windows Defender does not respond
  • How dangerous is the Drvcmna.exe miner?

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

    Initially, Drvcmna.exe malware makes your system overloaded. It is unable to run your applications now, because all CPU power is used by a virus. That malware does not care for your needs, all it focuses on is generating profits on you. Even if you are patient, and you waited until browser is open, you will likely experience extremely slow performance. Pages can open up for years, any kind of logins will likely take about a minute – just a nightmare for a person that works online.

    “Visible” harm is not a single unpleasant thing coin miners do to your system. Drvcmna.exe coin miner also deals damage to your OS. To perform all malevolent functions effectively, it wrecks the security mechanisms 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 lot of new entries – they are added by this coin miner to connect your system to a malicious mining network. All these changes are about to be reverted to the original in the process of system recovery.

    Hardware effects of coin miner activity

    Besides decreasing your PC’s performance, running at peak power for long times can trigger damage to your machine and raise electricity costs. PC elements are created to easily deal with high load, but they can do so only in case when they are in a good shape.

    Little and covered CPU fan is hard to damage. Meanwhile, graphic cards have large and easy-to-access rotors, which can be easily broke if touched while working, for example, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the really high load caused by Drvcmna.exe miner can easily lead to GPU failure. Video cards are also prone to have very fast wearing when used for cryptocurrency mining. It is likely an undesirable case when your GPU’s performance plunges 20-30% only after several weeks of being used in such a way.

    How did I get Drvcmna.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 through “severe” viruses. Adware often functions as a carrier for Drvcmna.exe malware injection: it shows you the banners, which have a link to malware downloading. Yes, this abstract “malware” may belong to any type – an additional adware, spyware, rogue or backdoor. But the statistics show that about 30% of all viruses spread through the malevolent banners are coin miners – and Drvcmna.exe is right with them.

    An additional way you could get this thing on your computer is by downloading it from the suspicious site as a part of a program. Users who spread hacked versions of favored programs (which do not demand the license key) have small chances to get paid. For this reason, there is a very big lure to add malware to the final package of the hacked app and get a coin for every installation. Prior to criticizing these guys for hacking and also malware spreading, ask yourself – is it alright to avoid purchasing the program in such a way? It is more affordable to pay $20-$30 at once than to pay a much greater figure for antivirus software and new parts for your computer.

    How to remove the Drvcmna.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 demands using specific app. Effective antivirus must have high performance at scanning and also be lightweight – in order to create no problems with usage even on weak PCs. Additionally, it is better to have on-run security in your security tool – to prevent the virus even before it starts. Microsoft Defender does not have these functions for various factors. That’s why I’d recommend you to use a third-party anti-malware program for that objective. GridinSoft Anti-Malware is a great option that fits each of the specified characteristics.2

    Before the virus removal, it is important to reboot your Windows into Safe Mode with Networking. Since Drvcmna.exe miner takes a lot of CPU capacity, it is required to stop 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.

    Boot into Windows Safe Mode

    Windows will reboot into recovery mode. In that mode, choose Troubleshoot→ Startup Settings→ Safe Mode with Networking. Press the corresponding button on your keyboard to choose that option.

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