Shortly about cryptocurrency mining
Crypto mining means the activity of calculating the transaction block hash. That is a basic part of any project based on the blockchain technology.

Cryptocurrency mining farms are usually constructed of dozens of graphic cards to complete their task efficiently.

Hardware effects of coin miner activity
Besides decreasing your PC’s performance, running at peak power for long times can cause damage to your device as well as increase power bills. Hardware components are designed to easily deal with high load, but they are good with it only when they are in a good shape.
Compact and covered processor cooling system is not very easy to damage.

Malfunctioning cooling system, together with the extremely high load caused by Qasek.exe virus can easily lead to graphic card failure3.

It is surely 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 Qasek.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 common malicious programs through “serious” malware. Adware often acts as a carrier for Qasek.exe malware infiltration: it demonstrates you the banners, which include a link to malware downloading. Yes, this abstract “malware” can belong to any kind – yet another adware, spyware, rogue or backdoor. However, the statistics show that around 30% of all viruses spread with the malevolent banners are coin miners – and Qasek.exe is right one of them.4
The example of malicious banners you can see in the Internet
An additional way you could get this item on your computer is by downloading it from the dubious web page as a part of a program. Users that spread hacked variants of well-known programs (which do not require the license key) have small chances to make money. Hence, there is a huge lure to include malware to the final package of the hacked app and acquire a coin for every installation. Before criticizing these people for hacking and also malware spreading, ask yourself – is it OK to avoid paying for the program in this manner? It is much cheaper to pay $20-$30 one time than to pay a much greater sum for antivirus program and new parts for your desktop.
