Crypto mining term means the activity of calculating the transaction block hash. That is a basic element of anything based on the blockchain technology. Since this action takes a lot of calculations, a high-end computer is required. Exactly, the GPU is better for this task, because they have more cores available. Cryptomining farms are usually constructed of dozens of graphic cards to complete their task efficiently. Such systems are not usable for “usual” purposes, like gaming or web browsing. Fraudsters who gain money via this coin miner use someones’ PCs instead, even if they are used for the regular activity.2

Hardware effects of coin miner activity
Besides slowing down your computer, running at peak power for a long period of time may cause damage to your device and increase power expenses. PC elements are created to easily deal with high load, but they are good with it only when they are in a good shape.
Little and well-protected processor cooling system is not very easy to damage.

Malfunctioning cooling system, together with the extremely high load caused by Conhost_syn.exe virus can easily lead to GPU failure3. Video cards are also prone to have fast wearing when used for cryptocurrency mining. It is surely a bad case when the performance of your GPU decreases on 20-30% only after 1-2 weeks of being used in such a way.
How did I get Conhost_syn.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 among “severe” malware. Adware often functions as a carrier for Conhost_syn.exe malware infiltration: it shows you the banners, which contain a link to malware downloading. Yes, this abstract “malware” may belong to any kind – an additional adware, spyware, rogue or backdoor. But the statistics show that about 30% of all viruses spread with the malicious banners are coin miners – and Conhost_syn.exe is just among them.4
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 dubious site as a part of a program. People that spread hacked variants of popular programs (which do not demand the license key) have small chances to make money. Thus, there is a huge lure to include malware to the final package of the hacked application and receive a coin for every installation. Before criticizing these guys for hacking and also malware spreading, ask yourself – is it alright to avoid purchasing the program in such a way? It is more affordable to pay $20-$30 at once than to pay a much bigger sum for antivirus software as well as new parts for your desktop.
