How did I get Sgmain.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 widespread malicious programs through “serious” malware. Adware sometimes acts as a carrier for Sgmain.exe malware injection: it shows you the banners, which include 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 around 30% of all malware spread with the malicious banners are coin miners – and Sgmain.exe is just among them.
Another way you could get this item on your computer is by downloading it from the dubious web page as a part of a program. People that spread hacked versions of well-known programs (which do not need the license key) have small chances to get paid. Therefore, there is a very big lure to add in malware to the final package of the hacked app and receive a coin for each setup. Prior to criticizing these people for hacking and also malware distribution, ask yourself – is it alright to avoid purchasing the program in this manner? It is more affordable to pay $20-$30 one time than to pay a much bigger sum for antivirus software as well as new parts for your PC.
