What is Zx.exe process?

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

As I have actually specified previously, Zx.exe is a coin miner trojan. The names of the executive file can be different, however, the effects are generally the same. Since coin miners focus on cryptocurrency mining, they use all possible hardware capacity of your personal computer to conduct this operation. This virus doesn’t pay attention to the fact that you may need to use your PC for other activities – it will consistently consume over 80% of your processor power.

Zx.exe Windows Process

Zx.exe – Extremely high CPU as well as GPU use

Besides CPU usage, some of the coin miners additionally use GPU power for their tasks. In that case, you will probably struggle also to see the mouse cursor moving – GPU is usually used on 100%. It is not as essential as CPU for system work, so Zx.exe coin miner viruses do not waste time on trifles and use all of it. It often can cause unhappy effects.

Shortly about cryptocurrency mining

Cryptocurrency mining means the action 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 strong PC is needed. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptocurrency mining farms are usually constructed of tens and hundreds of graphic cards to conduct their activity effectively. Such computer systems are not usable for “usual” purposes, like gaming or web browsing. Fraudsters who make profit via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

List of the typical coin miner symptoms

  • Your device overheats (system unit/laptop body is very hot)
  • You are not able to open your apps or they are opening for ages
  • Unknown process is running in the background and consumes your PC resources
  • Windows Defender does not respond
  • How dangerous is the Zx.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, Zx.exe virus makes your computer overloaded. It is unable to run your applications anymore, because all CPU power is consumed by a malware. That malware does not care for your necessities, all it focuses on is generating income on you. Even if you are patient, and you waited until browser is open, you will likely suffer from incredibly slow performance. Pages can open for years, any type of logins will likely take about a minute – just a headache for a person that works online.

    “Visible” harm is not a solitary bad activity coin miners do to your personal computer. Zx.exe coin miner additionally deals damage to your OS. To complete all malevolent functions properly, it wrecks the protection features of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent detection. 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 system to a malicious cryptomining network. All these adjustments are about to be gone back to the original in the process of system recovery.

    Hardware effects of coin miner activity

    Besides making your PC slow, performing at peak power for long times may trigger damage to your device and increase electricity costs. PC elements are designed to easily deal with high load, but they are good with it only in case when they are in a good shape.

    Tiny and covered CPU cooling system is hard to crack. Meanwhile, graphic cards have big and easy-to-access rotors, which can be easily cracked if affected while spinning, for instance, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the unusually high load caused by Zx.exe can easily lead to graphic card failure3. Video cards are also tend to have increased wearing when used for crypto mining. It is surely a bad case when the performance of your GPU decreases on 20-30% only after several weeks of being exploited in such a way.

    How did I get Zx.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 widespread malevolent programs through “serious” malware. Adware often works as a carrier for Zx.exe malware infiltration: it shows you the banners, which have a link to malware downloading. Yes, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. However, the statistics show that about 30% of all viruses spread through the malevolent banners are coin miners – and Zx.exe is right one of them.4

    The example of malicious banners you can see in the Internet

    An additional way you could get this item on your computer is by downloading it from the dubious website as a part of a program. People that spread hacked versions of favored programs (which do not need the license key) have small chances to earn money. For this reason, there is a very big lure to add malware to the final package of the hacked application and acquire a coin for every installation. Before blaming these guys for hacking and malware distribution, ask yourself – is it alright to avoid purchasing the program in this manner? It is much cheaper to pay $20-$30 at once than to pay a much bigger sum for antivirus program and new parts for your desktop.

    How to remove the Zx.exe miner from my PC?

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

    Removing such a virus needs making use of specific software. Proper security tool should have high capability at scanning and also be lightweight – in order to make no problems with utilization also on weak PCs. In addition, it is recommended to have proactive security in your protection tool – to stop the virus even before it starts. Microsoft Defender lacks these elements for various factors. That’s why I’d suggest you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is a superb choice that fits each of the specified characteristics.5

    Prior to the virus removal, it is important to reboot your Windows into Safe Mode with Networking. Since Zx.exe miner takes a lot of CPU capacity, 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.

    Boot into Windows Safe Mode

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