What is Regtool.exe process?

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

As I have actually specified before, Regtool.exe is a coin miner virus. The names of the .exe file can be diverse, but the effects are almost always the identical. Considering that coin miners aim at cryptocurrency mining, they utilize all possible hardware power of your PC to conduct this operation. This malware does not take note of the fact that you may need to make use of your desktop for other activities – it will constantly use over 80% of your processor power.

Regtool.exe – Extremely high CPU and GPU use

Besides CPU usage, some of the coin miners additionally make use of GPU power for their operations. In that situation, you will probably struggle also to see the mouse cursor moving – GPU is usually utilized on 100%. It is not as important as processor for system work, so Regtool.exe coin miner viruses don’t waste time on trifles and use all of it. It often can lead to sad consequences.

Shortly about cryptocurrency mining

Cryptocurrency mining term means the operation 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 strong desktop is required. Exactly, the video card is better for this purpose, because they have more cores available. Cryptomining farms are usually constructed of tens and hundreds of video cards to complete their task efficiently. Such computer systems are not usable for “general” 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

  • 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 Regtool.exe miner?

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

    First, Regtool.exe malware makes your PC overloaded. It is unable to run your applications now, because all CPU power is consumed by a virus. That malware does not care for your demands, all it focuses on is generating income on you. Even if you are patient, and you waited until web browser is open, you will likely struggle with exceptionally sluggish efficiency. Pages can open for years, any kind of logins will take about a minute – just a nightmare for a person who does a job online.

    “Visible” damage is not a solitary bad thing coin miners do to your system. Regtool.exe coin miner additionally deals damage to your operating system. To carry out all malevolent functions effectively, it wrecks the protection 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 lot of new entries – they are added by this trojan miner to connect your PC to a malicious mining network. All these adjustments are about to be gone back to the original in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides slowing down your computer, performing at peak power for a long period of time may cause damage to your machine as well as increase electricity costs. PC elements are created to easily deal with high load, but they can do so only when they are in a good shape.

    Small and covered CPU fan is not very easy to crack. Meanwhile, GPUs have large and easy-to-access rotors, which can be easily cracked if touched while spinning, for example, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the really high load caused by Regtool.exe can easily lead to graphic card failure3. Graphic cards are also tend to have fast wearing when used for cryptocurrency mining. It is surely an unwanted case when the performance of your video card plunges 20-30% just after several weeks of being used in such a way.

    How did I get Regtool.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 common malicious programs among “major” malware. Adware sometimes acts as a carrier for Regtool.exe malware injection: it shows you the banners, which contain a link to malware downloading. Sure, this abstract “malware” may belong to any type – an additional adware, spyware, rogue or backdoor. But the statistics show that around 30% of all viruses spread through the malevolent banners are coin miners – and Regtool.exe is just 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 website as a part of a program. People that spread hacked versions of popular programs (which do not require the license key) have small chances to make money. Therefore, there is a huge lure to add in malware to the final package of the hacked app and receive a coin for every setup. Before criticizing these individuals for hacking and malware spreading, 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 greater sum for antivirus program as well as new parts for your computer.

    How to remove the Regtool.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 requires making use of specific tool. Appropriate security tool should have high capability at scanning and also be lightweight – in order to create no problems with utilization also on weak PCs. On top of that, it is recommended to have proactive security in your security tool – to stop the virus even before it starts. Microsoft Defender lacks these functions for different factors. That’s why I’d advise you to use a third-party anti-malware program for that goal. GridinSoft Anti-Malware is an ideal choice that fits each of the specified qualities.5

    Before the malware removal, it is important to boot your Windows into Safe Mode with Networking. Since Regtool.exe miner consumes a lot of processor power, it is needed to halt it before launching the security program.

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