What is Zloop.exe process?

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

As I have specified earlier, Zloop.exe is a coin miner trojan virus. The names of the executive file can be different, however, the impacts are usually the same. Since coin miners aim at cryptocurrency mining, they use all available hardware capacity of your personal computer to perform this process. This virus does not pay attention to the fact that you probably want to use your computer for other activities – it will constantly use over 80% of your CPU power.

Zloop.exe – Extremely high CPU and GPU usage

Besides CPU consumption, some of the coin miners additionally make use of GPU power for their tasks. In that case, you will likely struggle also to see the mouse cursor moving – GPU is usually used on 100%. It is not as critical as processor for system work, so Zloop.exe coin miner viruses don’t waste time on trifles and utilize it all. It sometimes may result in sad effects.

Shortly about cryptocurrency mining

Cryptocurrency mining means the action of calculating the transaction block hash. That is a basic element of anything based on the blockchain technology. Since this action takes a lot of calculations, a very strong computer is required. Exactly, the video card is better for this task, because they have more cores available. Cryptocurrency mining farms are usually constructed of dozens of GPUs to conduct their activity effectively. Such computer systems are not usable for “normal” purposes, like gaming or browsing the Web. Fraudsters who gain money via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

List of the typical coin miner symptoms

  • Microsoft Defender is stopped;
  • CPU and GPU is loaded at 80-90% exactly after the system start
  • Cooling fans are running at high speed and create a lot of noise
  • A single process in Task Manager consumes all CPU and GPU power

    Initially, Zloop.exe malware makes your system overloaded. It is unable to run your applications now, since all CPU power is consumed by a malware. That malware does not care for your demands, all it focuses on is generating profits on you. Even if you are patient, and you waited until web browser is open, you will likely suffer from incredibly sluggish performance.

    “Visible” harm is not a solitary unpleasant thing coin miners do to your PC. Zloop.exe coin miner additionally deals damage to your operating system. To perform all malicious operations properly, it wrecks the security features of your system. You will likely see your Microsoft Defender disabled – malware stops it to avoid detection. If you check the HOSTS file, you will likely see a load of new notes – they are brought in by this trojan miner to connect your computer to a malicious cryptomining network. All these changes are about to be gone back to the initial state in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides slowing down your computer, performing at peak power for a long period of time may cause damage to your machine as well as raise electricity bills. PC elements are created to easily get along with high load, but they can do so only in case when they are in a good shape.

    Little and well-protected processor cooling system is quite hard to crack. Meanwhile, graphic cards have big and easy-to-access rotors, which can be easily cracked if affected while working, for example, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the really high load caused by Zloop.exe miner can easily lead to GPU failure3. Video cards are also prone to have very fast wearing when used for cryptocurrency mining. It is surely a bad situation when the performance of your GPU plunges 20-30% just after 1-2 weeks of being used in such a way.

    How did I get Zloop.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 prevalent malevolent programs through “serious” viruses. Adware sometimes works as a carrier for Zloop.exe malware infiltration: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. However, the statistics show that around 30% of all viruses spread through the malicious banners are coin miners – and Zloop.exe is just one of them.4

    Unwanted banners adware

    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 unreliable site as a part of a program. People that spread hacked variants of well-known programs (which do not require the license key) have small chances to earn money. Hence, there is a very big lure to add malware to the final package of the hacked app and receive a coin for each setup. Before blaming these people for hacking and also malware spreading, ask yourself – is it okay to avoid paying for the program in such a way? It is much cheaper to pay $20-$30 one time than to pay a much bigger sum for antivirus program and new parts for your computer.

    How to remove the Zloop.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 requires using special app. Proper anti-malware program should have high capability at scanning and also be lightweight – in order to make no problems with utilization also on weak PCs. On top of that, it is recommended to have on-run security in your security tool – to prevent the virus even before it launches. Microsoft Defender does not have these features 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 option that fits each of the mentioned features.5

    Before the malware removal, it is important to boot your operating system into Safe Mode with Networking. Since Zloop.exe miner takes a lot of processor capacity, 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.

    When your system is in Safe Mode, all third-party apps, just like the majority of non-critical 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.
