How did I get Fmcud.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 prevalent malicious programs through “severe” malware. Adware sometimes works as a carrier for Fmcud.exe malware infiltration: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” can belong to any type – yet another adware, spyware, rogue or backdoor. However, the statistics show that about 30% of all viruses spread with the malevolent banners are coin miners – and Fmcud.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 PC is by downloading it from the unreliable site as a part of a program. People that spread hacked variants of popular programs (which do not require the license key) have small chances to make money. For this reason, there is a huge temptation to add in malware to the final package of the hacked app and receive a coin for every installation. Before blaming these people for hacking and also malware spreading, ask yourself – is it OK to avoid paying for the program in this manner? It is more affordable to pay $20-$30 one time than to pay a much bigger figure for antivirus software and new parts for your PC.
