As I have actually mentioned earlier, Cthkctrl.exe is a coin miner trojan virus. The names of the .exe file can be diverse, however, the impacts are usually the same.

Besides CPU utilization, some of the coin miners also utilize GPU power for their tasks. In that case, you will struggle even to see the mouse arrow moving – GPU is often used on 100%.

Shortly about cryptocurrency mining
Cryptocurrency mining means the action of calculating the transaction block hash. That is a basic element of anything based on the blockchain technology. Since this action takes a lot of calculations, a very powerful computer is needed. Exactly, the GPU is better for this task, because they have more cores available. Cryptocurrency mining farms usually consist of dozens of graphic cards to complete their task efficiently. Such systems are not usable for “classic” purposes, like gaming or browsing the Web. Crooks who make profit via this coin miner use someones’ PCs instead, even if they are used for the regular activity.2

“Visible” harm is not a single bad activity coin miners perform to your PC. Cthkctrl.exe coin miner also deals damage to your operating system. To execute all malicious operations successfully, it wrecks the protection features 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 notes – they are brought in by this trojan miner to connect your computer to a malicious cryptomining network. All these adjustments shall be gone back to the initial state in the process of computer recovery.
Hardware effects of coin miner activity
Besides slowing down your PC, performing at peak level for a long period of time can trigger damage to your machine as well as increase power bills. Hardware components are created to easily get along with high load, but they are good with it only in case when they are in a good shape.
Tiny and covered processor cooling system is quite hard to damage. Meanwhile, graphic cards have big and easy-to-access rotors, which can be easily broke if touched while working, for example, by the user much earlier before the coin-miner injection. Malfunctioning cooling system, together with the extremely high load caused by Cthkctrl.exe malware can easily lead to GPU failure3. GPUs are also tend to have increased wearing when utilized for cryptocurrency mining. It is surely an unwanted situation when the performance of your graphic card plunges 20-30% only after 1-2 weeks of being exploited in such a way.
How did I get Cthkctrl.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 widespread malicious programs among “major” malware. Adware frequently works as a carrier for Cthkctrl.exe malware infiltration: it shows you the banners, which contain a link to malware downloading. Yes, this abstract “malware” can belong to any type – another adware, spyware, rogue or backdoor. But the statistics say that approximately 30% of all malware spread with the malicious banners are coin miners – and Cthkctrl.exe is just with them.4
The example of malicious banners you can see in the Internet
An additional way you could get this thing on your computer is by downloading it from the unreliable site as a part of a program. Users that spread hacked versions of favored programs (which do not need the license key) have small chances to get paid. Thus, there is a huge lure to add in malware to the final package of the hacked app and get a coin for every installation. Prior to criticizing these guys for hacking and malware spreading, ask yourself – is it alright to avoid buying the program in this manner? It is much cheaper to pay $20-$30 one time than to pay a much greater figure for antivirus software as well as new parts for your desktop.
How to remove the Cthkctrl.exe miner from my PC?

Eliminating such a virus requires using special app. Proper anti-malware program must 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 better to have on-run protection in your protection solution – to halt the virus even before it launches. Microsoft Defender lacks these elements for different reasons.

When your system is in Safe Mode, all third-party applications, along with the majority of non-crucial 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.
