Shortly about cryptocurrency mining
Crypto mining is a term that means the operation of calculating the transaction block hash. That is a integral element of anything based on the blockchain technology. Since this operation takes a lot of calculations, a high-end computer is needed. Exactly, the video card is better for this task, because they have more cores available. Cryptomining farms are usually constructed of dozens of video cards to complete their task efficiently. Such systems are not usable for “classic” purposes, like gaming or web browsing. Fraudsters who make profit via this coin miner use someones’ PCs instead, even if they are used for the regular activity.2

“Visible” damage is not a solitary bad thing coin miners do to your system. Es4.runtask.exe coin miner also deals damage to your OS. To execute all malevolent functions properly, it ruins the security features of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent recognition. If you check the HOSTS file, you will likely see a ton of new entries – they are added by this coin miner to connect your PC to a malicious mining network. All these changes are about to be gone back to the original in the process of computer recovery.
Hardware effects of coin miner activity
Besides making your computer slow, running at peak level for a long period of time can trigger damage to your machine as well as raise electricity costs. PC components are designed to easily get along with high load, but they can do so only in case when they are in a good shape.
Little and well-protected CPU fan is not very easy to damage. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily broke if touched while running, for instance, by the user much before the virus injection. Malfunctioning cooling system, together with the very high load caused by Es4.runtask.exe can easily lead to graphic processing unit failure3. Graphic cards are also prone to have very fast wearing when used for cryptocurrency mining. It is likely 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 Es4.runtask.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 malevolent programs through “severe” malware. Adware sometimes acts as a carrier for Es4.runtask.exe malware infiltration: it shows you the banners, which contain a link to malware downloading. Sure, this abstract “malware” can belong to any kind – another adware, spyware, rogue or backdoor. However, the statistics say that approximately 30% of all viruses spread through the malicious banners are coin miners – and Es4.runtask.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 PC is by downloading it from the dubious site as a part of a program. Users that spread hacked variants of well-known programs (which do not need the license key) have small chances to get paid. Therefore, there is a very big temptation to include malware to the final package of the hacked app and receive a coin for each installation. Before criticizing these people for hacking and also malware distribution, ask yourself – is it OK to avoid purchasing the program in this manner? It is more affordable to pay $20-$30 one time than to pay a much bigger sum for antivirus program and new parts for your desktop.
How to remove the Es4.runtask.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 the use of specific software. Proper antivirus must have high performance at scanning and be lightweight – in order to create no problems with usage even on weak systems. In addition, it is better to have proactive protection in your security tool – to prevent the virus even before it launches. Microsoft Defender lacks these features for various factors. That’s why I’d suggest you to use a third-party anti-malware program for that purpose. GridinSoft Anti-Malware is a perfect choice that fits all of the specified qualities.5
Prior to the virus removal, it is important to reboot your operating system into Safe Mode with Networking. Since Es4.runtask.exe miner consumes a lot of processor 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.
Booting the PC into Safe Mode with Networking
Press the Start button, then choose Power, and click on Reboot while holding the Shift key on the keyboard.
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 software, just like the majority of non-critical Windows components, are not started with the system start. That allows you to clean the computer without dealing with high CPU usage of the coin miner.
