Besides CPU usage, some of the coin miners additionally make use of GPU power for their operations. In that instance, you will probably struggle also to see the mouse arrow moving – GPU is often used on 100%. It is not as essential as CPU for system work, so Unpack.exe coin miner viruses don’t waste time on trifles and utilize it all. It often may result in unhappy effects.

Shortly about cryptocurrency mining

Cryptocurrency mining is a term that means the operation of calculating the transaction block hash. That is a basic part of anything based on the blockchain technology. Since this action takes a lot of calculations, a very strong machine is needed. Exactly, the GPU is better for this task, because they have more cores available. Cryptocurrency mining farms are usually constructed of dozens of graphic cards to complete their task efficiently. Such computer systems are not usable for “general” purposes, like gaming or web browsing. Fraudsters who make profit via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

    “Visible” harm is not a solitary negative thing coin miners do to your system. Unpack.exe coin miner likewise deals damage to your OS. To complete all malicious functions successfully, it ruins the protection mechanisms of your system. You will likely see your Microsoft Defender disabled – malware stops it to avoid recognition. If you check the HOSTS file, you will likely see a load of new entries – they are brought in by this trojan miner to connect your PC to a malicious cryptomining network. All these changes shall be thrown back to the initial state in the process of system recovery.

    Hardware effects of coin miner activity

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

    Tiny and covered processor cooling system is hard to broke. Meanwhile, graphic cards have large and easy-to-access rotors, which can be easily cracked if affected while spinning, for instance, by the user much earlier before the coin-miner injection. Malfunctioning cooling system, together with the really high load caused by Unpack.exe miner can easily lead to GPU failure3. GPUs are also tend to have very fast wearing when used for crypto mining. It is surely an unwanted situation when your GPU’s performance decreases on 20-30% only after several weeks of being used in such a way.

    How did I get Unpack.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 malicious programs through “severe” viruses. Adware frequently acts as a carrier for Unpack.exe malware injection: it shows you the banners, which include a link to malware downloading. Sure, this abstract “malware” can belong to any kind – an additional adware, spyware, rogue or backdoor. However, the statistics say that approximately 30% of all viruses spread through the malevolent banners are coin miners – and Unpack.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 thing on your PC is by downloading it from the suspicious site as a part of a program. People who spread hacked variants of favored programs (which do not demand 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 app and acquire a coin for each setup. Prior to blaming these individuals for hacking and also malware spreading, ask yourself – is it alright to avoid buying the program in this manner? It is much cheaper to pay $20-$30 at once than to pay a much bigger figure for antivirus software and new parts for your computer.

    How to remove the Unpack.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 specific tool. Proper security tool must have high efficiency at scanning and be lightweight – in order to make no problems with utilization even on weak systems. Furthermore, it is better to have on-run protection in your security tool – to prevent the virus even before it starts. Microsoft Defender lacks these functions for different factors. That’s why I’d suggest you to use a third-party anti-malware program for that goal. GridinSoft Anti-Malware is a great choice that fits each of the discussed qualities.5

    Prior to the malware removal, it is important to boot your Windows into Safe Mode with Networking. Since Unpack.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.

    When your system is in Safe Mode, all third-party applications, along with the majority of non-critical operating system components, are not started with the system start. That allows you to clean the system without dealing with high processor usage of the coin miner.
