What is Mfchain.exe process?
Mfchain.exe is a malicious process created by coin miner virus
As I have mentioned in the previous paragraph, Mfchain.exe is a coin miner trojan virus. The names of the executive file can be different, but the effects are usually the identical. Considering that coin miners focus on cryptocurrency mining, they utilize all possible hardware capacity of your PC to conduct this process. This virus does not care about the fact that you may need to make use of your desktop for other tasks – it will continuously consume over 80% of your processor power.
Mfchain.exe – Very high CPU as well as GPU use
Besides CPU consumption, some of the coin miners additionally make use of GPU power for their operations. In that case, you will likely struggle also to see the mouse cursor moving – GPU is often utilized on 100%. It is not as critical as processor for system work, so Mfchain.exe coin miner viruses don’t waste time on trifles and use it all. It often may lead to unhappy consequences.
Shortly about cryptocurrency mining
Cryptocurrency mining is a term that means the activity of calculating the transaction block hash. That is a integral element of any project based on the blockchain technology. Since this action takes a lot of calculations, a very powerful desktop is needed. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptomining farms are usually constructed of dozens of graphic cards to complete their task efficiently. Such computer 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

That malware does not care for your demands, all it pays attention to is making money on you. Even if you are patient, and you waited until web browser is open, you will likely experience extremely slow performance. Pages will open for years, any kind of logins will likely take about a minute – just a horror story for a person who does a job online.

“Visible” damage is not a single bad activity coin miners do to your personal computer. Mfchain.exe coin miner also deals damage to your operating system. To conduct all malevolent functions properly, it ruins the security 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 ton of new entries – they are added by this coin miner to connect your system to a malicious mining network. All these changes are about to be reverted to the initial state in the process of system recovery.
Hardware effects of coin miner activity
Besides making your computer slow, performing at peak level for long times can trigger damage to your device and increase electricity bills. PC components are designed to easily get along with high load, but they can do so only when they are in a good shape.
Tiny and covered processor cooling system is hard to crack. Meanwhile, GPUs have big and easy-to-access rotors, which can be easily broke if affected while running, for instance, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the extremely high load caused by Mfchain.exe miner can easily lead to GPU failure3. GPUs are also prone to have fast wearing when utilized for crypto mining. It is likely a bad 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 Mfchain.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 common malicious programs through “severe” malware. Adware often functions as a carrier for Mfchain.exe malware infiltration: it demonstrates you the banners, which contain 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 around 30% of all malware spread with the malevolent banners are coin miners – and Mfchain.exe is right one of them.4
The example of malicious banners you can see in the Internet
One more way you could get this thing on your PC is by downloading it from the dubious website as a part of a program. Users that spread hacked versions of well-known programs (which do not need the license key) have small chances to get paid. For this reason, there is a huge lure to add in malware to the final package of the hacked application and get a coin for every installation. Before blaming these people for hacking and malware distribution, ask yourself – is it alright to avoid buying the program in such a way? It is more affordable to pay $20-$30 one time than to pay a much greater figure for antivirus software as well as new parts for your PC.
How to remove the Mfchain.exe miner from my PC?
The best way to get rid of this coin miner virus is to use anti-malware software
Removing such a virus demands making use of special software. Appropriate antivirus must have high performance at scanning and be lightweight – in order to create no problems with utilization also on weak computers. On top of that, it is better to have on-run protection in your security tool – to halt the virus even before it starts. Microsoft Defender lacks these functions for various reasons. That’s why I’d advise you to use a third-party anti-malware program for that goal. GridinSoft Anti-Malware is a superb choice that fits all of the discussed features.5
Prior to the malware removal, it is important to reboot your operating system into Safe Mode with Networking. Since Mfchain.exe miner takes a lot of CPU power, it is required to stop it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.
Booting the PC into Safe Mode with Networking
Press the Start button, then choose Power, and click on Reboot while holding the Shift key on the keyboard.
Windows will reboot into recovery mode. In that mode, choose Troubleshoot→ Startup Settings→ Safe Mode with Networking. Press the corresponding button on your keyboard to choose that option.
When your PC is in Safe Mode, all third-party programs, just like the majority of non-crucial operating system components, are not started with the system start. That gives you the ability to clean the computer without dealing with high processor usage of the coin miner.
