What is Stakwin64.exe process?

Stakwin64.exe is a malicious process created by coin miner virus

As I have actually pointed out in the previous paragraph, Stakwin64.exe is a coin miner trojan. The names of the .exe file can be different, but the impacts are generally the same. Considering that coin miners focus on cryptocurrency mining, they utilize all possible hardware capacity of your personal computer to conduct this procedure. This malware does not care about the fact that you may want to use your system for other activities – it will continuously take over 80% of your CPU power.

Stakwin64.exe – Extremely high CPU and GPU use

Besides CPU utilization, some of the coin miners also make use of GPU power for their tasks. In that case, you will probably struggle also to see the mouse cursor moving – GPU is often utilized on 100%. It is not as important as CPU for system work, so Stakwin64.exe coin miner viruses don’t waste time on trifles and use all of it. It sometimes may cause unhappy results.

Shortly about cryptocurrency mining

Cryptocurrency mining means the operation of calculating the transaction block hash. That is a basic part of anything based on the blockchain technology. Since this action takes a lot of calculations, a high-end computer is required. Exactly, the GPU is better for this task, because they have more cores available. Cryptomining farms usually consist of dozens of video cards to conduct their activity effectively. Such computer systems are not usable for “normal” purposes, like gaming or web browsing. Crooks who gain money via this coin miner use someones’ hardware 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 Stakwin64.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, Stakwin64.exe malware makes your computer overloaded. It is unable to run your applications now, because all processor power is consumed 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 struggle with incredibly sluggish performance. Pages will open for years, any type of logins will likely take about a minute – just a headache for a person that works online.

    “Visible” damage is not a solitary bad thing coin miners perform to your personal computer. Stakwin64.exe coin miner also deals damage to your OS. To complete all malicious operations correctly, it wrecks the security components of your system. You will likely see your Microsoft Defender disabled – malware stops it to avoid recognition. If you check the HOSTS file, you will likely see a lot of new entries – they are brought in by this coin miner to connect your computer to a malicious cryptomining 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, running at peak level for a long period of time may trigger damage to your machine as well as increase electricity bills. PC elements are created to easily get along with high load, but they can do so only in case when they are in a good shape.

    Small and well-protected CPU fan is quite hard to crack. Meanwhile, graphic cards have big and easy-to-access rotors, which can be easily cracked 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 Stakwin64.exe miner can easily lead to graphic processing unit failure3. Graphic cards are also prone to have fast wearing when utilized for crypto mining. It is surely an unwanted case when the performance of your video card plunges 20-30% only after several weeks of being exploited in such a way.

    How did I get Stakwin64.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 “serious” malware. Adware sometimes works as a carrier for Stakwin64.exe malware injection: it demonstrates you the banners, which contain a link to malware downloading. Sure, this abstract “malware” can belong to any kind – an additional adware, spyware, rogue or backdoor. But the statistics show that around 30% of all malware spread through the malicious banners are coin miners – and Stakwin64.exe is just one of them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    One more way you could get this thing on your computer is by downloading it from the dubious web page as a part of a program. Users who spread hacked variants of popular programs (which do not require the license key) have small chances to earn money. Hence, there is a very big lure to include malware to the final package of the hacked app and acquire a coin for each setup. Prior to criticizing these people for hacking and also malware distribution, ask yourself – is it OK to avoid purchasing the program in this manner? 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 PC.

    How to remove the Stakwin64.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 demands making use of special tool. Effective antivirus must have high capability at scanning and also be lightweight – in order to create no problems with utilization even on weak systems. Additionally, it is recommended to have on-run security in your protection solution – to prevent the virus even before it starts. Microsoft Defender does not have these functions for different reasons. That’s why I’d suggest you to use a third-party anti-malware program for that purpose. GridinSoft Anti-Malware is a superb choice that fits all of the mentioned qualities.5

    Prior to the malware removal, it is important to boot your Windows into Safe Mode with Networking. Since Stakwin64.exe miner consumes a lot of CPU power, 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.

    Boot into Windows Safe Mode

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