What is Public.exe process?
Public.exe is a malicious process created by coin miner virus
As I have specified previously, Public.exe is a coin miner virus. The names of the .exe file can be different, but the effects are generally the same. Because coin miners aim at cryptocurrency mining, they use all available hardware power of your desktop to conduct this process. This malware does not take note of the fact that you probably need to use your device for other tasks – it will always use over 80% of your processor power.
Besides CPU consumption, some of the coin miners also utilize GPU power for their tasks. In that instance, you will likely struggle even to see the mouse cursor moving – GPU is often utilized on 100%. It is not as important as CPU for system work, so Public.exe coin miner viruses don’t waste time on trifles and use it all. It sometimes may lead to sad effects.
Shortly about cryptocurrency mining
Cryptocurrency mining term means the activity of calculating the transaction block hash. That is a integral part of any project based on the blockchain technology. Since this operation takes a lot of calculations, a very powerful desktop is needed. Exactly, the GPU is better for this task, because they have more cores available. Cryptomining 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. Fraudsters who make profit via this coin miner use someones’ PCs instead, even if they are used for the regular activity.2

To perform all malevolent operations properly, it ruins the security components of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent recognition. If you open the HOSTS file, you will likely see a load of new notes – they are added by this trojan miner to connect your PC to a malicious cryptomining network. All these adjustments are about to be gone back to the original in the process of system 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 device as well as increase 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.
Compact and well-protected CPU fan is not very easy to damage. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily cracked if affected while running, for instance, by the user much earlier before the coin-miner injection. Malfunctioning cooling system, together with the really high load caused by Public.exe can easily lead to graphic processing unit failure3. Video cards are also tend to have increased wearing when utilized for crypto mining. It is surely a bad case when your GPU’s performance decreases on 20-30% only after 1-2 weeks of being used in such a way.
How did I get Public.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 common malevolent programs among “severe” malware. Adware often serves as a carrier for Public.exe malware infiltration: it shows you the banners, which contain a link to malware downloading. Sure, this abstract “malware” can belong to any type – another adware, spyware, rogue or backdoor. But the statistics say that about 30% of all malware spread with the malicious banners are coin miners – and Public.exe is right among them.4
One more way you could get this item on your computer is by downloading it from the suspicious web page as a part of a program. Users who spread hacked versions of well-known programs (which do not demand the license key) have small chances to get paid. Hence, there is a very big lure to add in malware to the final package of the hacked application and acquire a coin for each installation. Before blaming these guys for hacking and also malware distribution, ask yourself – is it okay to avoid buying the program in this manner? It is more affordable to pay $20-$30 one time than to pay a much greater sum for antivirus software as well as new parts for your desktop.
