What is Windows security.exe process?
Windows security.exe is a malicious process created by coin miner virus
As I have mentioned in the introduction, Windows security.exe is a coin miner trojan virus. The names of the executive file can be diverse, but the consequences are usually the same. Since coin miners focus on cryptocurrency mining, they use all possible hardware power of your personal computer to perform this process. This malware does not care about the fact that you may want to make use of your PC for other activities – it will always consume over 80% of your CPU power.
Besides CPU usage, some of the coin miners also utilize GPU power for their operations. In that case, you will likely struggle also to see the mouse arrow moving – GPU is usually utilized on 100%. It is not as critical as CPU for system work, so Windows security.exe coin miner viruses don’t waste time on trifles and utilize all of it. It often can cause sad consequences.
Shortly about cryptocurrency mining
Cryptocurrency mining term means the action of calculating the transaction block hash. That is a basic part of any project based on the blockchain technology. Since this action takes a lot of calculations, a high-end desktop is needed. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptocurrency mining farms are usually constructed of tens and hundreds of GPUs to complete their task efficiently. Such computer systems are not usable for “usual” purposes, like gaming or browsing the Web. Crooks who gain money via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

“Visible” damage is not a solitary negative thing coin miners perform to your system. Windows security.exe coin miner also deals damage to your OS. To conduct all malicious functions successfully, it ruins the security components of your system. You will likely see your Microsoft Defender disabled – malware stops it to avoid detection. If you open the HOSTS file, you will likely see a number of new notes – they are added by this trojan miner to connect your PC to a malicious mining network. All these adjustments are about to be thrown back to the initial state in the process of system recovery.
Hardware effects of coin miner activity
Besides decreasing your PC’s performance, performing at peak level for long times can cause damage to your device as well as increase power bills. Hardware elements are designed to easily deal with high load, but they are good with it only in case when they are in a good shape.
Little and well-protected processor cooling system is not very easy to damage. Meanwhile, GPUs have big and easy-to-access fans, which can be easily broke if touched while working, for instance, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the extremely high load caused by Windows security.exe malware can easily lead to graphic processing unit failure3. Graphic cards are also tend to have increased wearing when utilized for crypto mining. It is surely an undesirable situation when your GPU’s performance decreases on 20-30% only after 1-2 weeks of being exploited in such a way.
How did I get Windows security.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 “serious” viruses. Adware sometimes acts as a carrier for Windows security.exe malware injection: it demonstrates you the banners, which have a link to malware downloading. Sure, this abstract “malware” may belong to any type – yet another adware, spyware, rogue or backdoor. But the statistics say that around 30% of all malware spread with the malevolent banners are coin miners – and Windows security.exe is right one of them.4
Another way you could get this thing on your computer is by downloading it from the unreliable 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. Thus, there is a huge temptation to add in malware to the final package of the hacked application and receive a coin for every setup. Prior to blaming these people for hacking and also malware spreading, ask yourself – is it alright to avoid paying for the program in such a way? It is more affordable to pay $20-$30 one time than to pay a much greater sum for antivirus program as well as new parts for your PC.
How to remove the Windows security.exe miner from my PC?

Effective anti-malware program should have high efficiency at scanning and also be lightweight – in order to create no problems with usage also on weak computers.
