Shortly about cryptocurrency mining
Cryptocurrency mining is a term that means the action of calculating the transaction block hash. That is a basic part of anything based on the blockchain technology. Since this action takes a lot of calculations, a very powerful machine is needed. Exactly, the graphic card is better for this task, because they have more cores available. Cryptocurrency mining farms are usually constructed of tens and hundreds of video cards to complete their task efficiently. Such systems are not usable for “general” purposes, like gaming or browsing the Web. Crooks who gain money via this coin miner use someones’ PCs instead, even if they are used for the regular activity.2

“Visible” damage is not a solitary unpleasant thing coin miners perform to your system. Brhost.exe coin miner additionally deals damage to your operating system. To conduct all malevolent operations correctly, it wrecks the security mechanisms of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent recognition. If you check the HOSTS file, you will likely see a load of new notes – they are brought in by this coin miner to connect your computer to a malicious mining network. All these adjustments are about to be gone back to the initial state in the process of system recovery.
Hardware effects of coin miner activity
Besides decreasing your PC’s performance, running at peak level for a long period of time may trigger damage to your device as well as raise power expenses. Hardware components are created to easily get along with high load, but they can do so only in case when they are in a good shape.
Small and covered processor cooling system is not very easy to damage. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily cracked if touched while running, for example, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the very high load caused by Brhost.exe miner can easily lead to graphic processing unit failure3. Video cards are also prone to have increased wearing when used for cryptocurrency mining. It is likely an unwanted situation when your GPU’s performance decreases on 20-30% just after several weeks of being exploited in such a way.
How did I get Brhost.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 widespread malevolent programs through “serious” malware. Adware often functions as a carrier for Brhost.exe malware injection: it demonstrates you the banners, which include a link to malware downloading. Sure, this abstract “malware” may belong to any kind – another adware, spyware, rogue or backdoor. But the statistics show that approximately 30% of all malware spread through the malicious banners are coin miners – and Brhost.exe is just with 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 dubious web page as a part of a program. Users who spread hacked versions of favored programs (which do not need the license key) have small chances to earn money. Therefore, there is a huge lure to add in malware to the final package of the hacked application and receive a coin for each setup. Prior to blaming these guys for hacking and malware spreading, ask yourself – is it alright to avoid paying for the program in such a way? It is more affordable to pay $20-$30 at once than to pay a much bigger sum for antivirus program as well as new parts for your computer.
How to remove the Brhost.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 making use of specific app. Proper anti-malware program must have high efficiency at scanning and also be lightweight – in order to create no problems with usage also on weak computers. Additionally, it is better to have on-run security in your protection tool – to halt the virus even before it starts. Microsoft Defender does not have these features for various factors.
