Tiny and covered processor cooling system is hard to crack. Meanwhile, GPUs have big and easy-to-access rotors, which can be easily broke if affected while running, for instance, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the extremely high load caused by Mfchain.exe miner can easily lead to GPU failure3. GPUs are also prone to have fast wearing when utilized for crypto mining. It is likely a bad case when the performance of your graphic card decreases on 20-30% just after several weeks of being exploited in such a way.
How did I get Mfchain.exe coin miner virus?
Coin miners are spread through different ways, but their main sources are malicious banners and programs from dubious sources
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 dubious website as a part of a program. Users that spread hacked versions of well-known programs (which do not need the license key) have small chances to get paid.
