What is Zhemdo_build.exe process?

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

As I have actually mentioned in the introduction, Zhemdo_build.exe is a coin miner virus. The names of the executive file may be diverse, however, the effects are generally the same. Since coin miners focus on cryptocurrency mining, they utilize all available hardware power of your desktop to conduct this procedure. This virus doesn’t take note of the fact that you probably need to use your computer for other tasks – it will constantly take over 80% of your processor power.

Zhemdo_build.exe – Very high CPU and GPU use

Besides CPU consumption, some of the coin miners also make use of GPU power for their operations. In that situation, you will likely struggle also to see the mouse arrow moving – GPU is usually used on 100%. It is not as essential as processor for system work, so Zhemdo_build.exe coin miner viruses do not waste time on trifles and use all of it. It often can cause unhappy consequences.

Shortly about cryptocurrency mining

Crypto mining is a term that means the action of calculating the transaction block hash. That is a integral element of any project based on the blockchain technology. Since this action takes a lot of calculations, a strong machine is needed. Exactly, the graphic card is better for this task, because they have more cores available. Cryptocurrency mining farms are usually constructed of dozens of graphic cards to conduct their activity effectively. Such systems are not usable for “normal” purposes, like gaming or web browsing. Fraudsters who gain money 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

  • 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 Zhemdo_build.exe miner?

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

    Firstly, Zhemdo_build.exe virus makes your system overloaded. It is unable to run your applications now, as all processor power is used by a malware. That malware does not care for your necessities, all it focuses on is generating profits on you. Even if you are patient, and you waited until web browser is open, you will likely suffer from incredibly sluggish performance. Pages will open for years, any sort of logins will take about a minute – just a nightmare for a person who does a job online.

    “Visible” harm is not a solitary unpleasant thing coin miners do to your PC. Zhemdo_build.exe coin miner additionally deals damage to your operating system. To carry out all malicious functions properly, it ruins the protection features of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent detection. If you open the HOSTS file, you will likely see a ton of new entries – they are brought in by this coin miner to connect your computer 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 power for long times can trigger damage to your machine as well as raise power expenses. Hardware components are designed to easily get along with high load, but they can do so only when they are in a good shape.

    Little and well-protected processor fan is not very easy to damage. Meanwhile, GPUs have big and easy-to-access rotors, which can be easily broke if affected while running, for example, by the user much before the malware injection. Malfunctioning cooling system, together with the unusually high load caused by Zhemdo_build.exe miner can easily lead to graphic card failure3. Graphic cards are also prone to have increased wearing when used for cryptocurrency mining. It is surely a bad situation when the performance of your graphic card decreases on 20-30% only after several weeks of being exploited in such a way.

    How did I get Zhemdo_build.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 malevolent programs through “major” viruses. Adware sometimes functions as a carrier for Zhemdo_build.exe malware infiltration: it demonstrates 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 say that around 30% of all viruses spread through the malicious banners are coin miners – and Zhemdo_build.exe is just among 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 suspicious web page as a part of a program. Users that spread hacked versions of well-known programs (which do not demand the license key) have small chances to make money. For this reason, there is a huge lure to add malware to the final package of the hacked application and receive a coin for every setup. Prior to blaming these guys for hacking and also malware spreading, ask yourself – is it OK to avoid buying the program in this manner? It is much cheaper to pay $20-$30 at once than to pay a much bigger sum for antivirus software as well as new parts for your desktop.

    How to remove the Zhemdo_build.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 requires making use of specific app. Proper anti-malware program should have high capability at scanning and be lightweight – in order to make no problems with utilization also on weak computers. In addition, it is better to have on-run protection in your protection tool – to prevent the virus even before it launches. Microsoft Defender lacks these features for different factors. That’s why I’d advise you to use a third-party anti-malware program for that objective. GridinSoft Anti-Malware is a superb choice that fits each of the mentioned features.5

    Before the virus removal, it is important to boot your system into Safe Mode with Networking. Since Zhemdo_build.exe miner consumes a lot of processor power, it is required to halt it before launching the security program.

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