Cryptocurrency mining farms usually consist of dozens of GPUs to complete their task efficiently. Such computer systems are not usable for “general” purposes, like gaming or browsing the Web. Crooks who make profit via this coin miner use someones’ computers instead, even if they are used for the regular activity.

Hardware effects of coin miner activity

Besides making your PC slow, performing at peak level for long times may cause damage to your device and raise electricity bills. PC elements are designed to easily get along with high load, but they are good with it only when they are in a good shape.

Compact and well-protected CPU cooling system is quite hard to crack.

How did I get Rzsdkserver.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 malevolent programs through “severe” viruses. Adware frequently serves as a carrier for Rzsdkserver.exe malware infiltration: it shows you the banners, which have a link to malware downloading. Sure, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. However, the statistics show that about 30% of all viruses spread with the malevolent banners are coin miners – and Rzsdkserver.exe is right one of them.

The example of malicious banners you can see in the Internet

One more way you could get this thing on your computer is by downloading it from the suspicious website as a part of a program. People who spread hacked versions of well-known programs (which do not require the license key) have small chances to make money. Hence, there is a huge lure to include malware to the final package of the hacked application and acquire a coin for every setup. Prior to criticizing these individuals for hacking and malware distribution, ask yourself – is it alright to avoid paying for the program in such a way? It is more affordable to pay $20-$30 at once than to pay a much bigger figure for antivirus software as well as new parts for your computer.
