Icuedevicepluginhost.exe – Really high CPU/GPU use

Besides CPU utilization, some of the coin miners additionally utilize GPU power for their operations. In that instance, you will struggle also to see the mouse cursor moving – GPU is often used on 100%. It is not as critical as CPU for system work, so iCUEDevicePluginHost.exe coin miner viruses do not waste time on trifles and utilize all of it. It often may lead to sad effects.

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
  • Is Coin Miner danger?

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

    First off, iCUEDevicePluginHost.exe malware makes your PC overloaded. It is unable to run your applications now, as all CPU power is consumed by a virus. That malware does not care for your demands, all it pays attention to is generating profits on you. Even if you are patient, and you waited until web browser is open, you will likely suffer from extremely sluggish efficiency. Pages can open for years, any type of logins will take about a minute – just a horror story for a person who does a job online.

    “Visible” damage is not a solitary negative activity coin miners do to your computer. iCUEDevicePluginHost.exe coin miner likewise deals damage to your operating system. To conduct all malicious functions successfully, it wrecks the protection mechanisms of your system. If you open the HOSTS file, you will likely see a number of new entries – they are added by this coin miner to connect your computer to a malicious mining network. All these changes are about to be thrown back to the original in the process of system recovery.

    Hardware effects of coin miner activity

    Besides making your computer slow, running at peak level for a long period of time can trigger damage to your machine and raise electricity costs. PC components are created to easily deal with high load, but they can do so only in case when they are in a good shape.

    Compact and covered processor fan is not very easy to broke. Meanwhile, GPUs have large and easy-to-access rotors, which can be easily broke if touched while spinning, for example, by the user much earlier before the coin-miner injection. Malfunctioning cooling system, together with the really high load caused by iCUEDevicePluginHost.exe virus can easily lead to graphic processing unit failure. Video cards are also prone to have fast wearing when used for cryptocurrency mining. It is likely a bad case when your GPU’s performance decreases on 20-30% only after several weeks of being used in such a way.

    How did I get 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 malicious programs through “major” viruses. Adware sometimes functions as a carrier for iCUEDevicePluginHost.exe malware infiltration: it shows you the banners, which include a link to malware downloading. Yes, this abstract “malware” may belong to any type – an additional adware, spyware, rogue or backdoor. But the statistics say that approximately 30% of all viruses spread with the malevolent banners are coin miners – and iCUEDevicePluginHost.exe is right one of them.

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    Another 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 demand the license key) have small chances to get paid. Thus, there is a huge temptation to include malware to the final package of the hacked app and receive a coin for each setup. Prior to criticizing these individuals for hacking and malware spreading, ask yourself – is it OK to avoid paying for the program in this manner? It is more affordable to pay $20-$30 at once than to pay a much bigger figure for antivirus program as well as new parts for your PC.

    How to remove the iCUEDevicePluginHost.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 using special tool. Proper security tool should have high efficiency at scanning and also be lightweight – in order to make no problems with usage also on weak PCs. On top of that, it is better to have on-run security in your protection tool – to prevent the virus even before it starts. Microsoft Defender does not have these features for various reasons. That’s why I’d recommend you to use a third-party anti-malware program for that objective. GridinSoft Anti-Malware is a great option that fits each of the discussed qualities.1

    Prior to the malware removal, it is important to boot your system into Safe Mode with Networking. Since iCUEDevicePluginHost.exe miner consumes 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.

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

    Boot into Windows Safe Mode

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