What is Assysctrlservice.exe process?

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

As I have mentioned in the previous paragraph, Assysctrlservice.exe is a coin miner virus. The names of the executive file can be different, but the consequences are almost always the same. Since coin miners aim at cryptocurrency mining, they use all available hardware capacity of your PC to perform this operation. This virus does not take note of the fact that you probably need to use your computer for other activities – it will constantly use over 80% of your CPU power.

Assysctrlservice.exe – Extremely high CPU/GPU usage

Besides CPU usage, 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 used on 100%. It is not as important as CPU for system work, so Assysctrlservice.exe coin miner viruses do not waste time on trifles and utilize it all. It sometimes may cause sad effects.

Shortly about cryptocurrency mining

Crypto mining term means the action of calculating the transaction block hash. That is a integral part of anything based on the blockchain technology. Since this operation takes a lot of calculations, a very powerful PC is needed. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptocurrency mining farms usually consist of dozens of graphic cards to conduct their activity effectively. Such systems are not usable for “usual” purposes, like gaming or browsing the Web. Fraudsters 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 Assysctrlservice.exe miner?

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

    Initially, Assysctrlservice.exe virus makes your computer overloaded. It is not able to run your applications now, since all CPU power is used by a virus. That malware does not care for your wants, all it focuses on is making money on you. Even if you are patient, and you waited until browser is open, you will likely suffer from extremely sluggish performance. Pages will open for years, any kind of logins will likely take about a minute – just a horror story for a person that does a job online.

    “Visible” harm is not a single unpleasant activity coin miners perform to your PC. Assysctrlservice.exe coin miner likewise deals damage to your operating system. To perform all malevolent operations successfully, it ruins the security mechanisms 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 ton of new entries – they are brought in by this coin miner to connect your system to a malicious mining network. All these changes are about to be thrown back to the initial state in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides making your computer slow, running at peak level for long times may trigger damage to your machine as well as increase electricity expenses. PC components are created to easily deal with high load, but they are good with it only when they are in a good shape.

    Compact and well-protected processor fan is quite hard to crack. Meanwhile, graphic cards have big and easy-to-access rotors, which can be easily broke if touched while working, for example, by the user much earlier before the coin-miner injection. Malfunctioning cooling system, together with the unusually high load caused by Assysctrlservice.exe can easily lead to graphic processing unit failure3. Video cards are also tend to have very fast wearing when used for cryptocurrency mining. It is surely a bad case when your GPU’s performance plunges 20-30% just after 1-2 weeks of being exploited in such a way.

    How did I get Assysctrlservice.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 prevalent malicious programs among “severe” viruses. Adware often serves as a carrier for Assysctrlservice.exe malware injection: it shows you the banners, which include a link to malware downloading. Yes, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. But the statistics show that approximately 30% of all viruses spread with the malevolent banners are coin miners – and Assysctrlservice.exe is just among them.4

    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 unreliable site as a part of a program. People that spread hacked versions of popular programs (which do not need the license key) have small chances to earn money. Thus, there is a huge temptation to add malware to the final package of the hacked app and acquire a coin for each setup. Prior to criticizing these guys for hacking and also malware distribution, ask yourself – is it alright to avoid paying for 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 as well as new parts for your PC.

    How to remove the Assysctrlservice.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 specific software. Effective anti-malware program should have high performance at scanning and be lightweight – in order to create no problems with usage even on weak computers. Additionally, it is better to have on-run security in your protection tool – to stop the virus even before it launches. Microsoft Defender lacks these functions for various reasons. That’s why I’d suggest you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is a great choice that fits each of the mentioned qualities.5

    Prior to the malware removal, it is important to reboot your system into Safe Mode with Networking. Since Assysctrlservice.exe miner consumes a lot of CPU capacity, it is required to stop 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.

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