Syn.exe process comes from a malicious program that can properly be defined as a coin miner trojan virus. That malware type uses your PC components to mine cryptocurrencies, generally – Monero or DarkCoin1. It makes your personal computer almost nonfunctional as a result of high CPU usage.
What is Syn.exe process?
Syn.exe is a malicious process created by coin miner virus
As I have specified earlier, Syn.exe is a coin miner trojan. The names of the executive file can be different, but the consequences are generally the same. Considering that coin miners focus on cryptocurrency mining, they use all possible hardware power of your desktop to perform this procedure. This virus does not pay attention to the fact that you may need to use your machine for other activities – it will consistently use over 80% of your processor power.
Syn.exe – Extremely high CPU/GPU use
Besides CPU usage, some of the coin miners also use GPU power for their operations. In that situation, you will likely struggle also to see the mouse cursor moving – GPU is usually utilized on 100%. It is not as important as CPU for system work, so Syn.exe coin miner viruses do not waste time on trifles and utilize it all. It sometimes can lead to sad consequences.
Shortly about cryptocurrency mining
Cryptocurrency mining is a term that means the action of calculating the transaction block hash. That is a basic element of any project based on the blockchain technology. Since this action takes a lot of calculations, a very strong machine is required. Exactly, the video card is better for this task, because they have more cores available. Cryptomining farms usually consist of dozens of video cards to conduct their activity effectively. Such computer systems are not usable for “classic” purposes, like gaming or browsing the Web. Fraudsters who gain money via this coin miner use someones’ hardware instead, even if they are used for the regular activity.2

How dangerous is the Syn.exe miner?
Coin miners does not deal damage to your files. However, they make a lot of unpleasant things with the whole system
First off, Syn.exe malware makes your computer overloaded. It is not able to run your applications anymore, as all processor power is consumed by a virus. That malware does not care for your necessities, all it focuses on is making money on you. Even if you are patient, and you waited until browser is open, you will likely struggle with extremely slow efficiency. Pages can open up for years, any sort of logins will take about a minute – just a horror story for a person who works online.

“Visible” harm is not a solitary negative thing coin miners do to your PC. Syn.exe coin miner also deals damage to your operating system. To perform all malicious functions successfully, it wrecks the protection mechanisms of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent detection. If you check the HOSTS file, you will likely see a number of new entries – they are brought in by this trojan miner to connect your PC to a malicious mining network. All these adjustments shall be thrown back to the initial state in the process of system recovery.
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 electricity bills. Hardware components are created to easily deal with high load, but they can do so only when they are in a good shape.
Compact and well-protected CPU cooling system is not very easy to damage. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily cracked if affected while spinning, for example, by the user much earlier before the virus injection. Malfunctioning cooling system, together with the really high load caused by Syn.exe miner can easily lead to GPU failure3. Video cards are also prone to have very fast wearing when utilized for crypto mining. It is likely an unwanted situation when the performance of your GPU plunges 20-30% only after several weeks of being exploited in such a way.
How did I get 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 the most common malevolent programs through “serious” viruses. Adware frequently works as a carrier for Syn.exe malware injection: it demonstrates you the banners, which include a link to malware downloading. Yes, this abstract “malware” can belong to any kind – an additional adware, spyware, rogue or backdoor. But the statistics show that approximately 30% of all malware spread with the malevolent banners are coin miners – and Syn.exe is right one of them.4
The example of malicious banners you can see in the Internet
Another way you could get this item on your computer is by downloading it from the suspicious site as a part of a program. People who spread hacked versions of well-known programs (which do not demand the license key) have small chances to make money. For this reason, there is a very big temptation to include malware to the final package of the hacked application and get a coin for every setup. Before criticizing these people for hacking and malware spreading, ask yourself – is it alright to avoid buying the program in such a way? It is much cheaper to pay $20-$30 at once than to pay a much bigger figure for antivirus program and new parts for your PC.
How to remove the Syn.exe miner from my PC?
The best way to get rid of this coin miner virus is to use anti-malware software
Getting rid of such a virus needs the use of special program. Appropriate security tool should have high efficiency at scanning and also be lightweight – in order to make no problems with usage also on weak PCs. Additionally, it is recommended to have on-run security in your security tool – to prevent the virus even before it starts. Microsoft Defender does not have these features for different reasons.
