What is Sys32a.exe process?

Sys32a.exe is a malicious process created by coin miner virus

As I have actually mentioned in the previous paragraph, Sys32a.exe is a coin miner trojan. The names of the executive file may be different, however, the consequences are usually the identical. Because coin miners focus on cryptocurrency mining, they utilize all possible hardware capacity of your personal computer to conduct this procedure. This malware does not take note of the fact that you probably want to make use of your system for other activities – it will continuously consume over 80% of your CPU power.

Sys32a.exe – Very high CPU and GPU use

Besides CPU consumption, some of the coin miners also utilize GPU power for their tasks. In that instance, you will struggle even to see the mouse cursor moving – GPU is usually utilized on 100%. It is not as vital as CPU for system work, so Sys32a.exe coin miner viruses do not waste time on trifles and utilize all of it. It often may result in unhappy consequences.

Shortly about cryptocurrency mining

Crypto mining means the action of calculating the transaction block hash. That is a basic part of anything based on the blockchain technology. Since this operation takes a lot of calculations, a very powerful machine is needed. Exactly, the GPU is better for this task, because they have more cores available. Cryptocurrency mining farms usually consist 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. Fraudsters who make profit 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

  • 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

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

    First of all, Sys32a.exe malware makes your PC overloaded. It is unable to run your applications now, because all processor power is consumed by a malware. That malware does not care for your demands, all it pays attention to is generating income on you. Even if you are patient, and you waited until browser is open, you will likely struggle with exceptionally sluggish efficiency. Pages can open up for years, any kind of logins will likely take about a minute – just a nightmare for a person who does a job online.

    “Visible” harm is not a single bad activity coin miners perform to your system. Sys32a.exe coin miner additionally deals damage to your OS. To conduct all malevolent operations successfully, it ruins the protection features of your system. You will likely see your Microsoft Defender disabled – malware stops it to avoid recognition. If you open the HOSTS file, you will likely see a lot of new notes – they are added by this trojan miner to connect your PC to a malicious mining network. All these adjustments shall be thrown back to the original in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides decreasing your computer’s performance, running at peak level for long times may cause damage to your machine and increase power bills. Hardware components are designed to easily get along with high load, but they are good with it only in case when they are in a good shape.

    Compact and well-protected CPU cooling system is not very easy to crack. Meanwhile, GPUs have big and easy-to-access rotors, which can be easily cracked if affected while working, for example, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the unusually high load caused by Sys32a.exe malware can easily lead to graphic card failure3. Graphic cards are also tend to have fast wearing when used for crypto mining. It is surely an unwanted case when your GPU’s performance plunges 20-30% just after 1-2 weeks of being used in such a way.

    How did I get Sys32a.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 “severe” malware. Adware frequently functions as a carrier for Sys32a.exe malware injection: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” can belong to any kind – an additional adware, spyware, rogue or backdoor. But the statistics say that approximately 30% of all malware spread with the malevolent banners are coin miners – and Sys32a.exe is right one of them.4

    The example of malicious banners you can see in the Internet

    One more way you could get this item on your computer is by downloading it from the unreliable site 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 get paid. Therefore, there is a huge lure to add in malware to the final package of the hacked app and acquire a coin for every 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 much cheaper to pay $20-$30 at once than to pay a much greater sum for antivirus program as well as new parts for your PC.

    How to remove the Sys32a.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 special program. Proper security tool must have high capability at scanning and be lightweight – in order to make no problems with utilization even on weak systems. Additionally, it is recommended to have proactive security in your protection solution – to stop the virus even before it starts. Microsoft Defender does not have these elements 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 an ideal choice that fits all of the specified characteristics.5

    Prior to the virus removal, it is important to reboot your Windows into Safe Mode with Networking. Since Sys32a.exe miner takes 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.

    Press the Start button, then choose Power, and click on Reboot while holding the Shift key on the keyboard.

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