What is Multiminer.win.exe process?

Multiminer.win.exe is a malicious process created by coin miner virus

As I have mentioned previously, Multiminer.win.exe is a coin miner trojan virus. The names of the executive file can be diverse, but the effects are generally the identical. Because coin miners aim at cryptocurrency mining, they use all available hardware capacity of your desktop to run this process. This virus doesn’t care about the fact that you may want to make use of your computer for other tasks – it will continuously use over 80% of your CPU power.

Multiminer.win.exe Windows Process

Multiminer.win.exe – Very high CPU as well as GPU use

Besides CPU consumption, some of the coin miners additionally make use of GPU power for their operations. In that instance, you will struggle also to see the mouse cursor moving – GPU is often utilized on 100%. It is not as critical as CPU for system work, so Multiminer.win.exe coin miner viruses don’t waste time on trifles and use all of it. It often can lead to bad effects.

Shortly about cryptocurrency mining

Crypto mining is a term that means the activity of calculating the transaction block hash. That is a basic part of any project based on the blockchain technology. Since this action takes a lot of calculations, a very strong machine is needed. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptocurrency mining farms are usually constructed of dozens of GPUs 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

  • Extremely bad performance
  • CPU/GPU cooler fan creates a lot of noise
  • High temperature of the device (for laptops)
  • 80-90% consumption of CPU/GPU resources by an unknown process
  • Microsoft Defender is not working
  • How dangerous is the Multiminer.win.exe miner?

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

    First of all, Multiminer.win.exe virus makes your PC overloaded. It is unable to run your applications now, since all processor power is consumed by a virus. That malware does not care for your necessities, all it pays attention to is making money on you. Even if you are patient, and you waited until browser is open, you will likely suffer from incredibly slow efficiency. Pages will open up for years, any kind of logins will take about a minute – just a nightmare for a person that works online.

    “Visible” damage is not a single unpleasant thing coin miners perform to your PC. Multiminer.win.exe coin miner additionally deals damage to your operating system. To conduct all malicious functions properly, it ruins the security features of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent recognition. If you open the HOSTS file, you will likely see a number of new notes – 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 computer recovery.

    Hardware effects of coin miner activity

    Besides slowing down your computer, performing at peak power for a long period of time may trigger damage to your machine and increase electricity expenses. PC elements are designed to easily deal with high load, but they can do so only when they are in a good shape.

    Compact and well-protected processor fan is not very easy to broke. Meanwhile, GPUs have large and easy-to-access rotors, which can be easily broke if touched while spinning, for example, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the very high load caused by Multiminer.win.exe miner can easily lead to GPU failure3. Video cards are also prone to have fast wearing when used for crypto mining. It is likely an unwanted situation when the performance of your video card plunges 20-30% only after 1-2 weeks of being exploited in such a way.

    How did I get Multiminer.win.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 common malevolent programs among “serious” viruses. Adware frequently serves as a carrier for Multiminer.win.exe malware infiltration: it demonstrates you the banners, which contain a link to malware downloading. Yes, this abstract “malware” may belong to any kind – yet another adware, spyware, rogue or backdoor. However, the statistics show that approximately 30% of all viruses spread through the malicious banners are coin miners – and Multiminer.win.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 PC is by downloading it from the dubious website as a part of a program. People that spread hacked versions of popular programs (which do not demand the license key) have small chances to earn money. Thus, there is a huge lure to include malware to the final package of the hacked app and receive a coin for every installation. Before blaming these people for hacking and malware spreading, ask yourself – is it okay to avoid buying the program in this manner? It is much cheaper to pay $20-$30 one time than to pay a much bigger figure for antivirus software and new parts for your PC.

    How to remove the Multiminer.win.exe miner from my PC?

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

    Getting rid of such a virus involves the use of special app. Proper anti-malware program should have high capability at scanning and be lightweight – in order to create no problems with usage even on weak PCs. Additionally, it is better to have on-run protection in your protection tool – to prevent the virus even before it starts. Microsoft Defender lacks these elements for different factors. That’s why I’d advise you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is a perfect option that fits all of the mentioned features.5

    Prior to the virus removal, it is important to boot your Windows into Safe Mode with Networking. Since Multiminer.win.exe miner consumes a lot of processor power, it is required to halt it before launching the security program.

    When your PC 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 processor usage of the coin miner.
