What is 12.exe process?

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

As I have pointed out in the introduction, 12.exe is a coin miner trojan virus. The names of the executive file can be diverse, but the consequences are generally the identical. Considering that coin miners focus on cryptocurrency mining, they use all possible hardware power of your personal computer to conduct this operation. This malware does not pay attention to the fact that you probably want to make use of your computer for other activities – it will consistently consume over 80% of your CPU power.

12.exe – Extremely high CPU and GPU use

Besides CPU consumption, some of the coin miners additionally make use of GPU power for their operations. In that situation, you will struggle even to see the mouse cursor moving – GPU is usually used on 100%. It is not as essential as processor for system work, so 12.exe coin miner viruses don’t waste time on trifles and use it all. It sometimes can lead to bad consequences.

Shortly about cryptocurrency mining

Crypto mining means the action of calculating the transaction block hash. That is a basic part of any project based on the blockchain technology. Since this action takes a lot of calculations, a very powerful machine is required. Exactly, the video card is better for this purpose, because they have more cores available. Cryptocurrency mining farms usually consist of dozens of graphic cards to conduct their activity effectively. Such computer systems are not usable for “general” purposes, like gaming or browsing the Web. Fraudsters who gain money 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

  • Your device overheats (system unit/laptop body is very hot)

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

    First of all, 12.exe virus makes your system overloaded. It is not able to run your applications now, as all processor power is used by a malware. That malware does not care for your wants, 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 performance. Pages can open up for years, any kind of logins will likely take about a minute – just a headache for a person who does a job online.

    “Visible” harm is not a single bad activity coin miners perform to your personal computer. 12.exe coin miner likewise deals damage to your OS. To carry out all malevolent functions correctly, it ruins the security components of your system. You will likely see your Microsoft Defender disabled – malware halts it to avoid recognition. If you check the HOSTS file, you will likely see a load of new entries – they are brought in by this trojan miner to connect your system to a malicious cryptomining network. All these adjustments are about to be reverted to the original in the process of system recovery.

    Hardware effects of coin miner activity

    Besides decreasing your computer’s performance, performing at peak power for long times can trigger damage to your machine and raise electricity costs. PC elements are created to easily get along with high load, but they are good with it only when they are in a good shape.

    Little and well-protected processor fan is hard to damage. Meanwhile, GPUs have big and easy-to-access fans, which can be easily broke if touched while spinning, for instance, by the user much earlier before the coin-miner injection. Malfunctioning cooling system, together with the extremely high load caused by 12.exe virus can easily lead to graphic card failure3. GPUs are also tend to have increased wearing when utilized for cryptocurrency mining. It is likely an undesirable situation when the performance of your video card decreases on 20-30% only after 1-2 weeks of being used in such a way.

    How did I get 12.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 “severe” viruses. Adware often acts as a carrier for 12.exe malware infiltration: it shows you the banners, which contain a link to malware downloading. Sure, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. But the statistics say that about 30% of all malware spread through the malevolent banners are coin miners – and 12.exe is right among them.4

    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 dubious website as a part of a program. Users who spread hacked variants of well-known programs (which do not require the license key) have small chances to get paid. Hence, there is a huge lure to add in malware to the final package of the hacked application and get a coin for each setup. Before blaming these people for hacking and also malware distribution, ask yourself – is it OK to avoid paying for the program in this manner? It is more affordable to pay $20-$30 at once than to pay a much bigger sum for antivirus program and new parts for your PC.

    How to remove the 12.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 demands making use of specific software. Appropriate security tool should have high efficiency at scanning and be lightweight – in order to create no problems with usage also on weak PCs. In addition, it is better to have on-run security in your protection 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 objective. GridinSoft Anti-Malware is an ideal option that fits each of the mentioned qualities.5

    Prior to the malware removal, it is important to reboot your operating system into Safe Mode with Networking. Since 12.exe miner consumes a lot of processor power, 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.

    When your system is in Safe Mode, all third-party programs, just like the majority of non-crucial operating 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.
