How did I get Jchd-4.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 malevolent programs through “major” viruses. Adware often functions as a carrier for Jchd-4.exe malware injection: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” can belong to any type – an additional adware, spyware, rogue or backdoor. But the statistics say that about 30% of all malware spread with the malevolent banners are coin miners – and Jchd-4.exe is just among them.3
The example of malicious banners you can see in the Internet
Another way you could get this item on your computer is by downloading it from the dubious website as a part of a program. Users who spread hacked versions of popular programs (which do not demand the license key) have small chances to earn money. Thus, there is a very big temptation to add malware to the final package of the hacked app and get a coin for every installation. Before blaming these guys for hacking and malware distribution, ask yourself – is it OK to avoid paying for the program in this manner? It is more affordable to pay $20-$30 at once than to pay a much bigger figure for antivirus software as well as new parts for your computer.
