    Hardware effects of coin miner activity

    Besides making your computer slow, performing at peak level for long times may cause damage to your machine and increase power bills. PC components are designed to easily get along with high load, but they can do so only in case when they are in a good shape.

    Small and covered CPU fan is quite hard to broke. Meanwhile, graphic cards have big and easy-to-access rotors, which can be easily cracked if touched while running, for example, by the user much before the malware injection.

    How did I get Dhcpsvchostdllcommon.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” viruses. Adware sometimes works as a carrier for Dhcpsvchostdllcommon.exe malware infiltration: it shows you the banners, which contain a link to malware downloading. Sure, this abstract “malware” can belong to any type – an additional adware, spyware, rogue or backdoor. However, the statistics show that around 30% of all malware spread with the malevolent banners are coin miners – and Dhcpsvchostdllcommon.exe is just one of them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    One more way you could get this thing on your PC is by downloading it from the suspicious web page as a part of a program. People that spread hacked variants of well-known programs (which do not need the license key) have small chances to earn money. Hence, there is a very big temptation to add malware to the final package of the hacked app and receive a coin for every setup. Prior to criticizing these guys for hacking and 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 computer.
