Shortly about cryptocurrency mining
Crypto mining term means the activity of calculating the transaction block hash. That is a integral element of any project based on the blockchain technology. Since this operation takes a lot of calculations, a high-end computer is needed. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptomining farms usually consist of tens and hundreds 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’ computers instead, even if they are used for the regular activity.2

Hardware effects of coin miner activity
Besides slowing down your computer, performing at peak power for a long period of time may cause damage to your device and increase power bills. PC elements are created to easily deal with high load, but they can do so only when they are in a good shape.
Small and well-protected CPU cooling system is not very easy to broke. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily cracked if touched while running, for example, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the extremely high load caused by Coresync.exe miner can easily lead to GPU failure3. GPUs are also prone to have very fast wearing when used for cryptocurrency mining. It is surely a bad case when the performance of your video card decreases on 20-30% only after several weeks of being used in such a way.
How did I get Coresync.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 through “major” malware. Adware frequently works as a carrier for Coresync.exe malware infiltration: it shows you the banners, which contain a link to malware downloading. Sure, this abstract “malware” can belong to any kind – an additional adware, spyware, rogue or backdoor. However, the statistics show that approximately 30% of all malware spread through the malicious banners are coin miners – and Coresync.exe is just with them.4
The example of malicious banners you can see in the Internet
An additional way you could get this thing on your PC is by downloading it from the suspicious web page as a part of a program. Users who spread hacked versions of well-known programs (which do not demand the license key) have small chances to get paid. Therefore, there is a very big lure to include malware to the final package of the hacked application and get a coin for each setup. Before blaming these guys for hacking and also malware distribution, ask yourself – is it okay to avoid buying the program in such a way? It is much cheaper to pay $20-$30 one time than to pay a much bigger figure for antivirus software and new parts for your PC.
How to remove the Coresync.exe miner from my PC?
