What is Winsysx64.exe process?

Winsysx64.exe is a malicious process created by coin miner virus

As I have actually mentioned in the introduction, Winsysx64.exe is a coin miner trojan virus. The names of the .exe file can be different, however, the effects are usually the identical. Because coin miners aim at cryptocurrency mining, they utilize all possible hardware capacity of your PC to perform this operation. This malware does not take note of the fact that you probably want to make use of your machine for other activities – it will continuously take over 80% of your processor power.

Winsysx64.exe – Really high CPU and GPU usage

Besides CPU usage, some of the coin miners additionally use GPU power for their operations. In that situation, you will likely struggle even to see the mouse cursor moving – GPU is usually utilized on 100%. It is not as essential as processor for system work, so Winsysx64.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 part of any project based on the blockchain technology. Since this operation takes a lot of calculations, a high-end computer is needed. Exactly, the video card is better for this task, because they have more cores available. Cryptomining farms are usually constructed of tens and hundreds of GPUs to conduct their activity effectively. Such computer systems are not usable for “general” purposes, like gaming or browsing the Web. Crooks who make profit 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 Winsysx64.exe miner?

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

    Initially, Winsysx64.exe virus makes your system overloaded. It is not able to run your applications anymore, since all CPU power is consumed by a virus. That malware does not care for your necessities, all it pays attention to is generating profits on you. Even if you are patient, and you waited until web browser is open, you will likely suffer from extremely slow efficiency. Pages will open up for years, any kind of logins will take about a minute – just a horror story for a person who does a job online.

    “Visible” damage is not a solitary bad thing coin miners perform to your system. Winsysx64.exe coin miner also deals damage to your OS. To complete all malicious functions correctly, it wrecks the security features of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent recognition. If you check the HOSTS file, you will likely see a load of new entries – they are added by this coin miner to connect your system to a malicious cryptomining network. All these adjustments are about to be thrown back to the original in the process of system recovery.

    Hardware effects of coin miner activity

    Besides decreasing your PC’s performance, running at peak level for a long period of time can trigger damage to your machine and increase power costs. Hardware components are created to easily get along with high load, but they are good with it only when they are in a good shape.

    Tiny and well-protected CPU cooling system is hard to crack. Meanwhile, GPUs have large and easy-to-access fans, which can be easily broke if affected while working, for instance, by the user much earlier before the coin-miner injection. Malfunctioning cooling system, together with the really high load caused by Winsysx64.exe can easily lead to graphic card failure3. Video cards are also prone to have increased wearing when used for cryptocurrency mining. It is surely a bad situation when your GPU’s performance decreases on 20-30% just after 1-2 weeks of being used in such a way.

    How did I get Winsysx64.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 malicious programs among “severe” viruses. Adware often serves as a carrier for Winsysx64.exe malware injection: it shows you the banners, which contain a link to malware downloading. Yes, this abstract “malware” can belong to any type – another adware, spyware, rogue or backdoor. However, the statistics say that about 30% of all malware spread with the malicious banners are coin miners – and Winsysx64.exe is right with them.4

    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 site as a part of a program. Users that spread hacked versions of favored programs (which do not demand the license key) have small chances to earn money. Thus, there is a huge lure to add in malware to the final package of the hacked app and receive a coin for each setup. Prior to criticizing these individuals for hacking and malware spreading, ask yourself – is it alright to avoid buying the program in such a way? It is more affordable to pay $20-$30 one time than to pay a much bigger sum for antivirus software and new parts for your desktop.

    How to remove the Winsysx64.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 needs using special software. Appropriate security tool must have high performance at scanning and also be lightweight – in order to make no problems with usage also on weak systems. Additionally, it is better to have on-run protection in your protection tool – to halt the virus even before it starts. Microsoft Defender does not have these elements for different reasons. That’s why I’d suggest you to use a third-party anti-malware program for that objective. GridinSoft Anti-Malware is a great choice that fits all of the mentioned features.5

    Before the malware removal, it is important to boot your operating system into Safe Mode with Networking. Since Winsysx64.exe miner takes a lot of processor capacity, it is needed to stop it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.

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