What is Fly.exe process?
Fly.exe is a malicious process created by coin miner virus
As I have mentioned earlier, Fly.exe is a coin miner trojan virus. The names of the .exe file can be different, however, the impacts are almost always the identical. Because coin miners focus on cryptocurrency mining, they utilize all available hardware power of your desktop to run this process. This virus doesn’t care about the fact that you probably need to use your system for other activities – it will always consume over 80% of your processor power.
Fly.exe – Extremely high CPU/GPU use
Besides CPU utilization, some of the coin miners also make use of GPU power for their tasks. In that situation, you will struggle even to see the mouse cursor moving – GPU is often used on 100%. It is not as vital as CPU for system work, so Fly.exe coin miner viruses do not waste time on trifles and use it all. It often can cause unhappy results.
Shortly about cryptocurrency mining
Crypto mining means the action of calculating the transaction block hash. That is a basic part of any project based on the blockchain technology. Since this operation takes a lot of calculations, a very powerful machine is needed. Exactly, the GPU is better for this task, because they have more cores available. Cryptocurrency mining farms usually consist 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 make profit via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

“Visible” damage is not a solitary negative activity coin miners perform to your system. Fly.exe coin miner likewise deals damage to your OS. To complete all malevolent operations properly, it wrecks the security components of your system. You will likely see your Microsoft Defender disabled – malware halts it to avoid recognition.

All these changes shall be gone back to the original in the process of PC recovery.
Hardware effects of coin miner activity
Besides decreasing your PC’s performance, performing at peak level for a long period of time may trigger damage to your machine and raise power costs. PC elements are designed to easily deal with high load, but they are good with it only in case when they are in a good shape.
Tiny and covered processor fan is not very easy to crack. Meanwhile, GPUs have big and easy-to-access fans, which can be easily cracked if touched while working, for instance, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the extremely high load caused by Fly.exe can easily lead to graphic card failure3. Graphic cards are also tend to have fast wearing when used for cryptocurrency 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 Fly.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 “major” viruses. Adware often works as a carrier for Fly.exe malware injection: it demonstrates 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 viruses spread with the malicious banners are coin miners – and Fly.exe is right with them.4
The example of malicious banners you can see in the Internet
An additional way you could get this thing on your PC is by downloading it from the unreliable site as a part of a program. Users that spread hacked versions of favored programs (which do not require the license key) have small chances to get paid. Hence, there is a very big lure to add malware to the final package of the hacked application and get a coin for each setup. Before criticizing these individuals for hacking and also malware distribution, ask yourself – is it OK to avoid buying the program in such a way? It is much cheaper to pay $20-$30 at once than to pay a much bigger sum for antivirus software and new parts for your PC.
How to remove the Fly.exe miner from my PC?
The best way to get rid of this coin miner virus is to use anti-malware software
Getting rid of such a virus needs using special tool. Proper security tool must have high performance at scanning and also be lightweight – in order to create no problems with utilization even on weak computers. Furthermore, it is recommended to have on-run protection in your security tool – to stop the virus even before it launches. Microsoft Defender does not have these functions for different factors. That’s why I’d recommend you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is a great option that fits all of the mentioned features.5
Prior to the virus removal, it is important to boot your Windows into Safe Mode with Networking. Since Fly.exe miner takes a lot of processor power, it is required to halt it before launching the security program.
