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.

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
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.
