What is Rtkngui64.exe process?

Rtkngui64.exe is a malicious process created by coin miner virus

As I have actually pointed out before, Rtkngui64.exe is a coin miner virus. The names of the .exe file may be different, but the impacts are usually the identical.

Besides CPU consumption, 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 often utilized on 100%. It is not as crucial as CPU for system work, so Rtkngui64.exe coin miner viruses do not waste time on trifles and use it all. It often may cause sad effects.

Shortly about cryptocurrency mining

Cryptocurrency mining means the operation of calculating the transaction block hash. That is a integral element of anything based on the blockchain technology. Since this action takes a lot of calculations, a strong machine 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 conduct their activity effectively. Such systems are not usable for “classic” purposes, like gaming or browsing the Web. 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

    “Visible” damage is not a solitary bad thing coin miners do to your PC. Rtkngui64.exe coin miner also deals damage to your OS. To carry out all malevolent operations properly, it ruins the security 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 brought in by this trojan miner to connect your system to a malicious mining network. All these adjustments shall be thrown back to the original in the process of system recovery.

    Hardware effects of coin miner activity

    Besides decreasing your computer’s performance, running at peak level for a long period of time can trigger damage to your device as well as increase power expenses. 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.

    Compact and covered processor cooling system is quite hard to broke. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily broke if touched while running, for example, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the really high load caused by Rtkngui64.exe miner can easily lead to graphic processing unit failure3. Video cards are also tend to have very fast wearing when utilized for crypto mining. It is surely an unwanted situation 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 Rtkngui64.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 works as a carrier for Rtkngui64.exe malware infiltration: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” can belong to any kind – yet another adware, spyware, rogue or backdoor. However, the statistics show that around 30% of all malware spread through the malevolent banners are coin miners – and Rtkngui64.exe is right 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 item on your PC is by downloading it from the dubious web page as a part of a program. People who spread hacked versions of popular programs (which do not need the license key) have small chances to make money. Therefore, there is a very big temptation to add in malware to the final package of the hacked application and get a coin for each setup. Before blaming these individuals for hacking and also malware distribution, ask yourself – is it okay to avoid buying the program in such a way? It is more affordable to pay $20-$30 at once than to pay a much bigger figure for antivirus software and new parts for your PC.

    How to remove the Rtkngui64.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 demands the use of special tool. Proper antivirus should have high capability at scanning and be lightweight – in order to make no problems with utilization also on weak PCs. Additionally, it is recommended to have on-run security in your security solution – to stop the virus even before it starts. Microsoft Defender lacks these elements for various reasons. That’s why I’d suggest you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is a great choice that fits all of the discussed features.5

    Before the malware removal, it is important to boot your Windows into Safe Mode with Networking. Since Rtkngui64.exe miner consumes a lot of CPU capacity, it is needed to stop 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

    windows safe mode boot option with command prompt

    When your PC is in Safe Mode, all third-party apps, just like the majority of non-crucial operating system components, are not launched with the system start. That allows you to clean the computer without dealing with high processor usage of the coin miner.
