What is Eyg99du.exe process?

Eyg99du.exe is a malicious process created by coin miner virus

As I have pointed out before, Eyg99du.exe is a coin miner virus. The names of the executive file can be different, but the effects are almost always the same. Since coin miners aim at cryptocurrency mining, they utilize all possible hardware power of your PC to conduct this process. This malware does not pay attention to the fact that you may want to make use of your desktop for other activities – it will consistently use over 80% of your CPU power.

Eyg99du.exe – Very high CPU as well as GPU usage

Besides CPU consumption, some of the coin miners also utilize GPU power for their tasks. In that situation, you will probably struggle also to see the mouse arrow moving – GPU is often utilized on 100%. It is not as critical as processor for system work, so Eyg99du.exe coin miner viruses don’t waste time on trifles and use it all. It sometimes can cause bad results.

Shortly about cryptocurrency mining

Crypto mining means the activity 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 required. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptomining farms usually consist of tens and hundreds of graphic cards to complete their task efficiently. Such systems are not usable for “general” purposes, like gaming or web browsing. Crooks 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

  • 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 Eyg99du.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, Eyg99du.exe virus makes your system overloaded. It is unable to run your applications now, because all CPU power is consumed by a malware. That malware does not care for your wants, 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 incredibly slow performance. Pages will 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 unpleasant activity coin miners perform to your system. Eyg99du.exe coin miner also deals damage to your OS. To conduct all malevolent operations effectively, it wrecks the protection mechanisms of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent detection. If you check the HOSTS file, you will likely see a ton of new notes – they are added by this coin miner to connect your PC to a malicious cryptomining network. All these adjustments are about to be reverted to the initial state in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides slowing down your PC, running at peak power for a long period of time may cause damage to your device as well as raise power bills. PC components are created to easily get along with high load, but they are good with it only when they are in a good shape.

    Little and well-protected CPU fan is not very easy to broke. Meanwhile, GPUs have big and easy-to-access fans, which can be easily cracked if affected while running, for example, by the user much earlier before the coin-miner injection. Malfunctioning cooling system, together with the really high load caused by Eyg99du.exe can easily lead to graphic card failure3. Graphic cards are also prone to have increased wearing when utilized for crypto mining. It is likely an undesirable situation when your GPU’s performance plunges 20-30% just after several weeks of being used in such a way.

    How did I get Eyg99du.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 “major” malware. Adware frequently functions as a carrier for Eyg99du.exe malware infiltration: it shows you the banners, which include a link to malware downloading. Sure, this abstract “malware” can belong to any kind – yet another adware, spyware, rogue or backdoor. But the statistics show that approximately 30% of all viruses spread through the malicious banners are coin miners – and Eyg99du.exe is just one of them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    One more way you could get this thing on your PC is by downloading it from the untrustworthy web page as a part of a program. Users that spread hacked versions of well-known programs (which do not need the license key) have small chances to earn money. For this reason, there is a very big temptation to add malware to the final package of the hacked app and get a coin for each setup. Before blaming these guys for hacking and also malware distribution, ask yourself – is it OK to avoid paying for 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 and new parts for your desktop.

    How to remove the Eyg99du.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 demands making use of special tool. Appropriate security tool must have high capability at scanning and also be lightweight – in order to make no problems with usage even on weak PCs. In addition, it is better to have on-run protection in your security tool – to stop the virus even before it starts. Microsoft Defender lacks these elements for different reasons. That’s why I’d advise you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is a great choice that fits all of the specified features.5

    Before the malware removal, it is important to reboot your operating system into Safe Mode with Networking. Since Eyg99du.exe miner consumes a lot of CPU capacity, it is required to halt it before launching the security program.
