    How did I get Sgm.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 among “severe” malware. Adware sometimes serves as a carrier for Sgm.exe malware infiltration: it shows you the banners, which have a link to malware downloading. Sure, this abstract “malware” may belong to any kind – another adware, spyware, rogue or backdoor. But the statistics show that around 30% of all malware spread through the malicious banners are coin miners – and Sgm.exe is just with them.3

    The example of malicious banners you can see in the Internet

    One more way you could get this item on your PC is by downloading it from the untrustworthy website as a part of a program. Users who spread hacked variants of well-known programs (which do not need the license key) have small chances to get paid. Hence, there is a huge temptation to add malware to the final package of the hacked application and acquire a coin for each installation. Prior to blaming these guys for hacking and also malware distribution, ask yourself – is it alright to avoid buying the program in this manner? It is much cheaper to pay $20-$30 one time than to pay a much bigger figure for antivirus software and new parts for your computer.
