What is Unpackcheck.exe process?

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

As I have actually pointed out in the introduction, Unpackcheck.exe is a coin miner trojan. The names of the .exe file may be different, but the consequences are generally the same. Since coin miners aim at cryptocurrency mining, they utilize all possible hardware power of your PC to run this process. This malware does not care about the fact that you may want to use your PC for other tasks – it will consistently consume over 80% of your CPU power.

Unpackcheck.exe – Very high CPU and GPU use

Besides CPU consumption, some of the coin miners additionally utilize GPU power for their operations. In that case, you will likely struggle also to see the mouse cursor moving – GPU is often used on 100%. It is not as crucial as CPU for system work, so Unpackcheck.exe coin miner viruses do not waste time on trifles and use all of it. It often can lead to bad effects.

Shortly about cryptocurrency mining

Crypto mining term means the operation of calculating the transaction block hash. That is a integral element of any project based on the blockchain technology. Since this operation takes a lot of calculations, a very powerful machine is needed. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptomining farms are usually constructed of dozens of GPUs to complete their task efficiently. Such computer systems are not usable for “general” purposes, like gaming or web browsing. Fraudsters who gain money via this coin miner use someones’ PCs instead, even if they are used for the regular activity.

    Firstly, Unpackcheck.exe virus makes your system overloaded. It is unable to run your applications now, as all CPU power is used by a virus. That malware does not care for your needs, all it focuses on is generating profits on you. Even if you are patient, and you waited until browser is open, you will likely suffer from incredibly slow performance.

    “Visible” damage is not a single unpleasant activity coin miners do to your PC. Unpackcheck.exe coin miner likewise deals damage to your operating system. To execute all malevolent operations successfully, it wrecks the security components of your system. You will likely see your Microsoft Defender disabled – malware stops it to avoid recognition. If you open the HOSTS file, you will likely see a load of new entries – they are brought in by this trojan miner to connect your computer to a malicious cryptomining network. All these changes are about to be reverted to the original in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides making your computer slow, performing at peak level for long times may cause damage to your device and raise power bills. 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.

    Compact and covered CPU cooling system is quite hard to damage. Meanwhile, GPUs have large and easy-to-access fans, which can be easily broke if touched while working, for instance, by the user much before the virus injection. Malfunctioning cooling system, together with the very high load caused by Unpackcheck.exe can easily lead to GPU failure2. Video cards are also tend to have very fast wearing when used for cryptocurrency mining. It is likely an unwanted case when the performance of your graphic card plunges 20-30% just after several weeks of being exploited in such a way.

    How did I get Unpackcheck.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 prevalent malicious programs through “major” viruses. Adware frequently acts as a carrier for Unpackcheck.exe malware injection: it shows you the banners, which include 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 about 30% of all viruses spread with the malicious banners are coin miners – and Unpackcheck.exe is just among them.

    The example of malicious banners you can see in the Internet

    An additional way you could get this thing on your PC is by downloading it from the dubious web page as a part of a program. People who spread hacked variants of favored programs (which do not need the license key) have small chances to earn money. Thus, there is a very big temptation to add in malware to the final package of the hacked application and get a coin for every installation. Prior to criticizing these individuals for hacking and also malware distribution, ask yourself – is it alright to avoid purchasing the program in such a way? It is more affordable to pay $20-$30 at once than to pay a much greater sum for antivirus program as well as new parts for your computer.

    How to remove the Unpackcheck.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 the use of specific software. Proper security tool should have high capability at scanning and also be lightweight – in order to make no problems with usage even on weak computers. Additionally, it is better to have proactive security in your protection tool – to halt the virus even before it starts. Microsoft Defender does not have these elements for various reasons. That’s why I’d advise you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is a superb choice that fits all of the discussed qualities.3

    Prior to the virus removal, it is important to reboot your Windows into Safe Mode with Networking. Since Unpackcheck.exe miner takes a lot of CPU power, it is needed to stop it before launching the security program.

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