What is Flop.exe process?

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

As I have actually pointed out earlier, Flop.exe is a coin miner trojan virus. The names of the .exe file may be different, however, the effects are usually the identical. Since coin miners aim at cryptocurrency mining, they use all available hardware capacity of your personal computer to run this process. This malware doesn’t pay attention to the fact that you may want to make use of your device for other activities – it will constantly consume over 80% of your CPU power.

Flop.exe Windows Process

Flop.exe – Very high CPU as well as GPU usage

Besides CPU consumption, some of the coin miners also utilize GPU power for their operations. In that instance, you will struggle also to see the mouse arrow moving – GPU is usually utilized on 100%. It is not as important as processor for system work, so Flop.exe coin miner viruses don’t waste time on trifles and utilize it all. It often may result in sad results.

Shortly about cryptocurrency mining

Crypto mining is a term that means the operation of calculating the transaction block hash. That is a integral element of anything based on the blockchain technology. Since this action takes a lot of calculations, a high-end computer is required. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptocurrency mining farms are usually constructed of dozens of graphic cards to complete their task efficiently. Such 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
  • Microsoft Defender is not working
  • How dangerous is the Flop.exe miner?

    Coin miners does not deal damage to your files. However, they make a lot of unpleasant things with the whole system

    First of all, Flop.exe malware makes your system overloaded. It is unable to run your applications anymore, since all CPU power is used by a malware. That malware does not care for your demands, all it pays attention to is generating income on you. Even if you are patient, and you waited until web browser is open, you will likely experience incredibly slow performance. Pages will open for years, any type of logins will take about a minute – just a nightmare for a person who works online.

    “Visible” harm is not a solitary bad activity coin miners do to your computer. Flop.exe coin miner also deals damage to your operating system. To complete all malicious operations successfully, it wrecks the protection features of your system. You will likely see your Microsoft Defender disabled – malware halts it to avoid recognition. If you check the HOSTS file, you will likely see a number of new entries – they are added by this coin miner to connect your system to a malicious mining network. All these adjustments shall be reverted to the original in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides decreasing your system’s performance, running at peak level for a long period of time can trigger damage to your device and raise power expenses. Hardware elements are created to easily get along with high load, but they can do so only when they are in a good shape.

    Small and well-protected CPU cooling system is hard to broke. Meanwhile, GPUs have large and easy-to-access fans, which can be easily broke if affected while working, for instance, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the really high load caused by Flop.exe malware can easily lead to GPU failure3. Graphic cards are also prone to have fast wearing when used for cryptocurrency mining. It is likely an unwanted case when your GPU’s performance plunges 20-30% just after several weeks of being used in such a way.

    How did I get Flop.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 malevolent programs among “major” viruses. Adware frequently acts as a carrier for Flop.exe malware injection: it shows you the banners, which have a link to malware downloading. Yes, this abstract “malware” may belong to any type – yet another adware, spyware, rogue or backdoor. However, the statistics say that approximately 30% of all malware spread with the malevolent banners are coin miners – and Flop.exe is just with them.4

    The example of malicious banners you can see in the Internet

    Another way you could get this item on your PC is by downloading it from the dubious web page as a part of a program. People who spread hacked variants of popular programs (which do not require the license key) have small chances to make money. Thus, there is a very big lure to include malware to the final package of the hacked application and acquire a coin for every installation. Before blaming these individuals for hacking and also malware distribution, ask yourself – is it OK 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 and new parts for your desktop.

    How to remove the Flop.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 involves the use of specific program. Proper anti-malware program must have high capability at scanning and also be lightweight – in order to make no problems with utilization even on weak PCs. On top of that, it is recommended to have on-run protection in your security solution – to halt the virus even before it launches. Microsoft Defender lacks these functions for different factors. That’s why I’d recommend you to use a third-party anti-malware program for that objective. GridinSoft Anti-Malware is a superb option that fits each of the mentioned features.5

    Prior to the virus removal, it is important to boot your operating system into Safe Mode with Networking. Since Flop.exe miner consumes a lot of processor capacity, it is needed to stop it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.

    Press the Start button, then choose Power, and click on Reboot while holding the Shift key on the keyboard.

    When your PC is in Safe Mode, all third-party programs, along with the majority of non-crucial operating system components, are not launched with the system start. That allows you to clean the computer without dealing with high CPU usage of the coin miner.
