What is Btfs.exe process?
Btfs.exe is a malicious process created by coin miner virus
As I have actually mentioned earlier, Btfs.exe is a coin miner virus. The names of the .exe file can be diverse. However, the effects are almost always identical. Since coin miners aim at cryptocurrency mining, they use all available hardware power of your desktop to run this procedure. This virus does not note that you probably need to use your device for other tasks – it will constantly take over 80% of your CPU power.
Besides CPU consumption, some coin miners also use GPU power. In that instance, you will struggle even to see the mouse arrow moving – GPU is usually used on 100%. It is not as critical as the processor for system work, so Btfs.exe coin miner viruses don’t waste time on trifles and utilize it all. It sometimes may lead to sad effects.
Shortly about cryptocurrency mining
Cryptocurrency mining means the activity of calculating the transaction block hash. That is a basic part of any project based on blockchain technology. Since this action requires many calculations, a mighty machine is required. The video card is better for this task because more cores are available. Cryptocurrency mining farms usually have dozens of video cards to complete their task efficiently. Such systems are not usable for “usual” purposes, like gaming or browsing the Web. Fraudsters who gain money via this coin miner use someone’s computers instead, even if they are used for regular activity.1

How dangerous is the Btfs.exe miner?
Coin miners do not deal damage to your files. However, they do a lot of unpleasant things with the whole system
First off, Btfs.exe virus makes your system overloaded. It cannot run your applications since a virus uses all processor power. That malware does not care for your needs; it only focuses on making money. Even if you are patient and wait until the web browser opens, you will likely experience prolonged performance. Pages will open for years; any logins will take about a minute – just a horror story for someone who works online.

“Visible” damage is not a single unpleasant activity coin miners do to your system. Btfs.exe coin miner additionally deals damage to your OS. To execute all malicious functions properly ruins the protection features 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 several new notes – brought in by this trojan miner to connect your computer to a malicious mining network. All these adjustments are about to be reverted to the original in the process of computer recovery.
Hardware effects of coin miner activity
Besides slowing down your PC, running at peak level for extended times may trigger damage to your device as well as increase power costs. Hardware components are created to get along with high load quickly, but they are good with it only when they are in good shape.
Tiny and well-protected CPU cooling system is hard to damage. Meanwhile, graphic cards have big and easy-to-access rotors, which can be easily broken if touched while working, for instance, by the user much earlier before the coin-miner injection. Malfunctioning cooling system, together with the extremely high load caused by Btfs.exe, can easily lead to graphic card failure2. Graphic cards are also prone to wear more when used for crypto mining. It is surely an unwanted case when your GPU’s performance plunges 20-30% just after 1-2 weeks of being used in such a way.
How did I get the Btfs.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 among “serious” viruses. Adware frequently works as a carrier for Btfs.exe malware injection: it shows you the banners, which include a link to malware downloads. This abstract “malware” may belong to any type – yet another adware, spyware, rogue or backdoor. However, the statistics say that around 30% of all viruses spread with malicious banners are coin miners – and Btfs.exe is just among them.3
One more way you could get this thing on your PC is by downloading it from the untrustworthy web page as a part of a program. People who spread hacked variants of well-known programs (which do not require the license key) have small chances to earn money. For this reason, there is a huge temptation to add in malware to the final package of the hacked app and acquire a coin for each installation. 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 one time than to pay a much bigger sum for an antivirus program as well as new parts for your desktop.
How to remove the Btfs.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 needs using special software. Proper security tools should have high efficiency at scanning and be lightweight – to create no problems with usage, even on weak systems.
