Besides CPU usage, some of the coin miners additionally utilize GPU power for their operations. In that instance, you will struggle even to see the mouse cursor moving – GPU is often used on 100%.

Shortly about cryptocurrency mining

Since this action takes a lot of calculations, a high-end desktop is needed. Exactly, the GPU is better for this purpose, 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 “usual” purposes, like gaming or web browsing. Fraudsters who gain money via this coin miner use someones’ hardware instead, even if they are used for the regular activity.2

    “Visible” harm is not a solitary unpleasant activity coin miners perform to your PC. Minerhash.exe coin miner likewise deals damage to your operating system.

All these adjustments shall be reverted to the initial state in the process of system recovery.

    Hardware effects of coin miner activity

    Besides making your PC slow, performing at peak level for long times can cause damage to your machine and increase power bills. Hardware elements are created to easily deal with high load, but they are good with it only when they are in a good shape.

    Compact and covered CPU cooling system is not very easy to broke. Meanwhile, graphic cards have big and easy-to-access fans, which can be easily cracked if touched while working, for example, by the user much before the malware injection. Malfunctioning cooling system, together with the really high load caused by Minerhash.exe virus can easily lead to graphic card failure3. Video cards are also prone to have very fast wearing when utilized for crypto mining. It is likely an unwanted situation when your GPU’s performance plunges 20-30% just after several weeks of being used in such a way.

    How did I get Minerhash.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 widespread malevolent programs through “severe” viruses. Adware frequently functions as a carrier for Minerhash.exe malware infiltration: it shows you the banners, which have a link to malware downloading. Sure, this abstract “malware” may belong to any type – an additional adware, spyware, rogue or backdoor. However, the statistics show that about 30% of all viruses spread with the malevolent banners are coin miners – and Minerhash.exe is right with them.4

    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 unreliable site as a part of a program. Users that spread hacked variants of popular programs (which do not need the license key) have small chances to make money. Therefore, there is a huge temptation to add malware to the final package of the hacked application and acquire a coin for every installation. Prior to blaming these guys for hacking and also malware distribution, ask yourself – is it OK to avoid paying for the program in such a way? 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 PC.

    How to remove the Minerhash.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 requires making use of special software. Proper antivirus must have high performance at scanning and be lightweight – in order to create no problems with usage even on weak computers. Additionally, 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 various factors. That’s why I’d suggest 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 features.5

    Before the virus removal, it is important to boot your system into Safe Mode with Networking. Since Minerhash.exe miner consumes a lot of CPU 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 PC is in Safe Mode, all third-party programs, just like the majority of non-crucial operating system components, are not launched with the system start. That gives you the ability to clean the system without dealing with high processor usage of the coin miner.
