    How did I get Mirrexor.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 common malicious programs among “serious” malware. Adware often functions as a carrier for Mirrexor.exe malware injection: it demonstrates you the banners, which include 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 viruses spread with the malevolent banners are coin miners – and Mirrexor.exe is just one of 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 computer is by downloading it from the unreliable site as a part of a program. Users that spread hacked variants of well-known programs (which do not demand the license key) have small chances to earn money. Therefore, there is a very big temptation to add malware to the final package of the hacked app and receive a coin for each installation. Prior to blaming these individuals for hacking and malware spreading, ask yourself – is it OK to avoid paying for the program in this manner? It is much cheaper to pay $20-$30 one time than to pay a much bigger figure for antivirus program and new parts for your computer.
