Besides CPU usage, some of the coin miners additionally make use of GPU power for their operations. In that case, you will struggle also to see the mouse arrow moving – GPU is usually utilized on 100%. It is not as vital as CPU for system work, so Cpu32.exe coin miner viruses do not waste time on trifles and utilize all of it. It often can cause bad consequences.

Shortly about cryptocurrency mining

Crypto mining means the activity of calculating the transaction block hash. That is a basic element of any project based on the blockchain technology. Since this action takes a lot of calculations, a strong machine is required. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptocurrency mining farms usually consist of tens and hundreds of GPUs to conduct their activity effectively. Such systems are not usable for “normal” purposes, like gaming or browsing the Web. Crooks who gain money via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

    “Visible” damage is not a solitary unpleasant activity coin miners do to your computer. Cpu32.exe coin miner likewise deals damage to your OS. To execute all malevolent operations effectively, it ruins the protection components of your system. You will likely see your Microsoft Defender disabled – malware stops it to avoid detection. If you open the HOSTS file, you will likely see a lot 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 gone back to the original in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides making your PC slow, performing at peak level for long times can trigger damage to your machine and raise electricity expenses. PC components are created to easily get along with high load, but they are good with it only when they are in a good shape.

    Small and covered CPU fan is quite hard to crack. Meanwhile, graphic cards have big and easy-to-access rotors, which can be easily cracked if affected while working, for instance, by the user much before the malware injection. Malfunctioning cooling system, together with the really high load caused by Cpu32.exe virus can easily lead to graphic processing unit failure3. GPUs are also tend to have fast wearing when utilized for crypto mining. It is surely an undesirable case when the performance of your graphic card decreases on 20-30% just after several weeks of being exploited in such a way.

    How did I get Cpu32.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 “serious” malware. Adware often acts as a carrier for Cpu32.exe malware infiltration: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. However, the statistics say that around 30% of all malware spread with the malevolent banners are coin miners – and Cpu32.exe is right among them.4

    The example of malicious banners you can see in the Internet

    An additional way you could get this item on your computer is by downloading it from the suspicious site as a part of a program. People who spread hacked variants of favored programs (which do not demand the license key) have small chances to get paid. Therefore, 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. Before criticizing these people for hacking and malware spreading, ask yourself – is it okay to avoid buying the program in such a way? It is more affordable to pay $20-$30 one time than to pay a much bigger sum for antivirus software as well as new parts for your desktop.

    How to remove the Cpu32.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 app. Effective security tool should have high performance at scanning and be lightweight – in order to create no problems with usage also on weak systems. Additionally, it is better to have on-run protection in your protection tool – to stop the virus even before it starts. Microsoft Defender does not have these elements for different factors. That’s why I’d advise you to use a third-party anti-malware program for that purpose. GridinSoft Anti-Malware is a superb choice that fits all of the specified qualities.5
