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. Since this action takes a lot of calculations, a very strong machine is needed. Exactly, the graphic card is better for this task, because they have more cores available. Cryptomining 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 browsing the Web.

Hardware effects of coin miner activity
Besides decreasing your computer’s performance, performing at peak power for long times can cause damage to your device and increase power bills. PC components are created to easily get along with high load, but they can do so only when they are in a good shape.
Little and well-protected processor cooling system is quite hard to crack. 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 before the coin-miner injection. Malfunctioning cooling system, together with the extremely high load caused by Prezi.exe miner can easily lead to graphic card failure3.

How did I get Prezi.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 prevalent malevolent programs among “severe” malware. Adware frequently works as a carrier for Prezi.exe malware infiltration: it shows you the banners, which include a link to malware downloading. Sure, this abstract “malware” can belong to any type – 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 Prezi.exe is right one of them.4
The example of malicious banners you can see in the Internet
Another way you could get this thing on your computer is by downloading it from the unreliable web page as a part of a program. Users who spread hacked versions of popular programs (which do not require the license key) have small chances to earn money. Hence, there is a huge temptation to include malware to the final package of the hacked application and acquire a coin for each setup. Before blaming these people for hacking and also malware distribution, ask yourself – is it okay to avoid buying the program in such a way? It is much cheaper to pay $20-$30 one time than to pay a much greater sum for antivirus program as well as new parts for your desktop.
