What is Fluorosulfonic.exe process?

Fluorosulfonic.exe is a malicious process created by coin miner virus

As I have actually specified earlier, Fluorosulfonic.exe is a coin miner trojan virus. The names of the executive file can be diverse, but the impacts are almost always the identical. Since coin miners aim at cryptocurrency mining, they utilize all possible hardware power of your PC to run this process. This malware does not pay attention to the fact that you probably need to use your desktop for other tasks – it will always consume over 80% of your processor power.

Fluorosulfonic.exe – Extremely high CPU/GPU use

Besides CPU utilization, some of the coin miners also utilize GPU power for their tasks. In that case, you will probably struggle even to see the mouse cursor moving – GPU is usually used on 100%. It is not as critical as CPU for system work, so Fluorosulfonic.exe coin miner viruses do not waste time on trifles and utilize all of it. It often can lead to unhappy consequences.

Shortly about cryptocurrency mining

Cryptocurrency mining means the operation of calculating the transaction block hash. That is a basic part of anything based on the blockchain technology. Since this operation takes a lot of calculations, a very strong computer is needed. Exactly, the video card is better for this task, because they have more cores available. Cryptomining farms are usually constructed of tens and hundreds of graphic cards to conduct their activity effectively. Such computer systems are not usable for “normal” purposes, like gaming or web browsing. Crooks who make profit via this coin miner use someones’ hardware instead, even if they are used for the regular activity.2

List of the typical coin miner symptoms

  • Extremely bad performance
  • CPU/GPU cooler fan creates a lot of noise
  • High temperature of the device (for laptops)
  • 80-90% consumption of CPU/GPU resources by an unknown process

    “Visible” harm is not a single negative activity coin miners perform to your system. Fluorosulfonic.exe coin miner likewise deals damage to your operating system. To complete all malicious operations effectively, it ruins the protection features of your system. You will likely see your Microsoft Defender disabled – malware halts it to avoid recognition. If you open the HOSTS file, you will likely see a lot of new entries – they are added by this trojan miner to connect your system to a malicious cryptomining network. All these changes shall be thrown back to the initial state in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides slowing down your computer, running at peak level for long times can cause damage to your device and increase electricity expenses. PC components are created to easily deal with high load, but they can do so only when they are in a good shape.

    Compact and well-protected processor fan 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 earlier before the malware injection. Malfunctioning cooling system, together with the unusually high load caused by Fluorosulfonic.exe virus can easily lead to GPU failure3. Video cards are also tend to have increased wearing when utilized for cryptocurrency mining. It is surely a bad situation when the performance of your video card plunges 20-30% just after several weeks of being used in such a way.

    How did I get Fluorosulfonic.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 through “severe” viruses. Adware often serves as a carrier for Fluorosulfonic.exe malware infiltration: it shows you the banners, which contain a link to malware downloading. Sure, this abstract “malware” can belong to any kind – another adware, spyware, rogue or backdoor. But the statistics say that around 30% of all malware spread through the malicious banners are coin miners – and Fluorosulfonic.exe is right with them.4

    The example of malicious banners you can see in the Internet

    One more way you could get this item on your PC is by downloading it from the dubious site as a part of a program. Users that 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 very big temptation to add malware to the final package of the hacked app and get a coin for every setup. Before criticizing these individuals for hacking and malware distribution, ask yourself – is it alright 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 and new parts for your desktop.

    How to remove the Fluorosulfonic.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 involves the use of special software. Appropriate anti-malware program must have high efficiency at scanning and also be lightweight – in order to make no problems with usage also on weak PCs. Furthermore, it is better to have proactive protection in your protection tool – to halt the virus even before it starts. Microsoft Defender lacks these functions for different reasons. That’s why I’d advise you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is a great option that fits each of the specified qualities.5

    Prior to the malware removal, it is important to reboot your Windows into Safe Mode with Networking. Since Fluorosulfonic.exe miner consumes a lot of processor power, it is needed to halt it before launching the security program.
