What is Cxproper.exe process?

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

As I have specified in the previous paragraph, Cxproper.exe is a coin miner trojan. The names of the executive file may be different, but the consequences are generally the same. Considering that coin miners focus on cryptocurrency mining, they utilize all available hardware capacity of your desktop to run this operation. This virus does not care about the fact that you may want to use your computer for other tasks – it will always use over 80% of your processor power.

Cxproper.exe – Really high CPU and GPU use

Besides CPU utilization, some of the coin miners additionally make use of GPU power for their tasks. In that case, you will probably struggle also to see the mouse cursor moving – GPU is usually used on 100%. It is not as vital as CPU for system work, so Cxproper.exe coin miner viruses don’t waste time on trifles and use it all. It often may lead to bad results.

Shortly about cryptocurrency mining

Crypto mining term 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 strong computer is needed. Exactly, the video card is better for this task, because they have more cores available. Cryptocurrency mining farms usually consist of tens and hundreds of graphic cards to complete their task efficiently. Such systems are not usable for “usual” 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

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 Cxproper.exe miner?

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

    First off, Cxproper.exe malware makes your system overloaded. It is unable to run your applications anymore, as all processor power is consumed by a virus. That malware does not care for your needs, all it focuses on is generating income on you. Even if you are patient, and you waited until browser is open, you will likely struggle with incredibly sluggish performance. Pages will open for years, any kind of logins will take about a minute – just a nightmare for a person who works online.

    “Visible” harm is not a single bad activity coin miners do to your PC. Cxproper.exe coin miner likewise deals damage to your operating system. To perform all malicious operations correctly, it ruins the security components of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent detection. If you open the HOSTS file, you will likely see a ton of new notes – they are brought in by this coin miner to connect your computer to a malicious cryptomining network. All these changes are about to be thrown back to the initial state in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides making your PC slow, running at peak power for a long period of time can cause damage to your machine and raise electricity costs. Hardware components are designed to easily deal with high load, but they can do so only in case when they are in a good shape.

    Little and well-protected CPU cooling system is not very easy to damage. Meanwhile, GPUs have large and easy-to-access fans, which can be easily cracked if touched while running, for example, by the user much before the virus injection. Malfunctioning cooling system, together with the unusually high load caused by Cxproper.exe miner can easily lead to graphic card failure3. GPUs are also prone to have increased wearing when used for cryptocurrency mining. It is surely an undesirable situation when the performance of your video card decreases on 20-30% just after several weeks of being used in such a way.

    How did I get Cxproper.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 “severe” viruses. Adware sometimes works as a carrier for Cxproper.exe malware injection: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” can belong to any type – another adware, spyware, rogue or backdoor. However, the statistics show that around 30% of all malware spread with the malevolent banners are coin miners – and Cxproper.exe is just with them.

    The example of malicious banners you can see in the Internet

    Another way you could get this item on your computer is by downloading it from the untrustworthy web page as a part of a program. People who spread hacked variants of well-known programs (which do not need the license key) have small chances to get paid. Therefore, there is a huge lure to add malware to the final package of the hacked application and receive a coin for every setup. Prior to blaming these people for hacking and also malware spreading, ask yourself – is it okay to avoid purchasing the program in this manner? It is more affordable to pay $20-$30 at once than to pay a much greater figure for antivirus software as well as new parts for your computer.

    How to remove the Cxproper.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 needs using special app. Appropriate antivirus should have high performance at scanning and also be lightweight – in order to make no problems with usage even on weak computers. In addition, it is recommended to have proactive protection in your protection solution – to stop the virus even before it starts. Microsoft Defender does not have these functions for various reasons. That’s why I’d recommend you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is a superb choice that fits all of the specified qualities.4

    Prior to the malware removal, it is important to boot your Windows into Safe Mode with Networking.
