What is Ethminer.exe process?

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

As I have mentioned previously, Ethminer.exe is a coin miner trojan. The names of the executive file may be diverse, however, the impacts are generally the same. Considering that coin miners aim at cryptocurrency mining, they use all available hardware power of your personal computer to perform this procedure. This virus doesn’t care about the fact that you probably want to use your PC for other tasks – it will always use over 80% of your CPU power.

Ethminer.exe – Extremely high CPU/GPU use

Besides CPU utilization, some of the coin miners also make use of GPU power for their operations. In that case, you will likely struggle also to see the mouse arrow moving – GPU is often utilized on 100%. It is not as critical as processor for system work, so Ethminer.exe coin miner viruses don’t waste time on trifles and use it all. It often may cause unhappy consequences.

Shortly about cryptocurrency mining

Cryptocurrency mining is a term that means the operation of calculating the transaction block hash. That is a basic element of anything based on the blockchain technology. Since this operation takes a lot of calculations, a high-end machine is required. Exactly, the video card is better for this purpose, because they have more cores available. Cryptocurrency mining farms usually consist of tens and hundreds of video cards to conduct their activity effectively. Such systems are not usable for “usual” 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

  • Your device overheats (system unit/laptop body is very hot)

    First off, Ethminer.exe malware makes your PC overloaded. It is unable to run your applications now, because all CPU power is used by a malware. That malware does not care for your demands, all it pays attention to is making money on you.

    “Visible” damage is not a single negative activity coin miners do to your PC. Ethminer.exe coin miner additionally deals damage to your OS. To conduct all malevolent functions properly, it wrecks the protection mechanisms of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent detection. If you open the HOSTS file, you will likely see a number of new entries – they are added by this coin miner to connect your computer to a malicious cryptomining network. All these adjustments shall be reverted to the initial state in the process of system recovery.

    Hardware effects of coin miner activity

    Besides decreasing your PC’s performance, performing at peak level for long times may cause damage to your machine and raise power bills. Hardware elements are created to easily get along with high load, but they can do so only when they are in a good shape.

    Little and covered processor cooling system is quite hard to damage. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily cracked if touched while spinning, for example, by the user much before the virus injection. Malfunctioning cooling system, together with the very high load caused by Ethminer.exe can easily lead to graphic card failure3. GPUs are also prone to have increased wearing when used for crypto mining. It is surely an unwanted case when the performance of your video card plunges 20-30% only after 1-2 weeks of being used in such a way.

    How did I get Ethminer.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 through “major” viruses. Adware sometimes serves as a carrier for Ethminer.exe malware infiltration: it shows you the banners, which contain a link to malware downloading. Sure, this abstract “malware” can belong to any kind – yet another adware, spyware, rogue or backdoor. However, the statistics show that approximately 30% of all malware spread with the malevolent banners are coin miners – and Ethminer.exe is right among them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    Another way you could get this thing on your computer is by downloading it from the unreliable site as a part of a program. People who spread hacked variants of favored programs (which do not need the license key) have small chances to make money. Therefore, there is a huge temptation to include 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 okay to avoid buying the program in such a way? It is more affordable to pay $20-$30 one time than to pay a much greater sum for antivirus software and new parts for your computer.

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

    The best way to get rid of this coin miner virus is to use anti-malware software

    Removing such a virus demands making use of specific tool. Proper antivirus must have high capability at scanning and be lightweight – in order to create no problems with utilization also on weak systems. On top of that, it is better to have on-run security in your security tool – to halt the virus even before it launches. Microsoft Defender lacks these functions for different factors. That’s why I’d advise you to use a third-party anti-malware program for that goal. GridinSoft Anti-Malware is a perfect choice that fits all of the mentioned characteristics.5

    Before the virus removal, it is important to reboot your operating system into Safe Mode with Networking. Since Ethminer.exe miner consumes a lot of CPU capacity, it is needed 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.

    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 apps, along with the majority of non-crucial operating system components, are not launched with the system start. That gives you the ability to clean the system without dealing with high CPU usage of the coin miner.
