    How did I get Msoia.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 malicious programs through “serious” malware. Adware frequently acts as a carrier for Msoia.exe malware infiltration: it shows you the banners, which include a link to malware downloading. Sure, this abstract “malware” can belong to any kind – an additional adware, spyware, rogue or backdoor. However, the statistics say that about 30% of all viruses spread through the malevolent banners are coin miners – and Msoia.exe is just with them.3

    Unwanted banners adware

    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 suspicious website as a part of a program. People that spread hacked variants of popular programs (which do not need the license key) have small chances to earn money. Therefore, there is a huge lure to include malware to the final package of the hacked application and receive a coin for each installation. Prior to blaming these individuals for hacking and also malware spreading, ask yourself – is it okay to avoid paying for the program in such a way? It is much cheaper to pay $20-$30 one time than to pay a much greater sum for antivirus program and new parts for your desktop.

    How to remove the Msoia.exe miner from my PC?

    The best way to get rid of Msoia.exe virus is to use anti-malware software

    Getting rid of such a virus demands using special software. Appropriate antivirus must have high efficiency at scanning and also be lightweight – in order to create no problems with usage even on weak systems. Additionally, it is recommended to have on-run protection in your protection tool – to stop the virus even before it starts. Microsoft Defender lacks these functions for different factors. That’s why I ‘d advise you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is a perfect choice that fits each of the discussed qualities.4
