Shortly about cryptocurrency mining
Cryptocurrency mining means the operation 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 strong computer is needed. Exactly, the video card is better for this purpose, because they have more cores available. Cryptomining farms usually consist of dozens of graphic cards to conduct their activity effectively. Such systems are not usable for “general” purposes, like gaming or web browsing. Fraudsters who make profit via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

“Visible” damage is not a single negative activity coin miners do to your PC. \’at.exe coin miner also deals damage to your OS. To execute all malevolent functions properly, it wrecks the protection components of your system. You will likely see your Microsoft Defender disabled – malware halts it to avoid detection. If you check the HOSTS file, you will likely see a load of new entries – they are added by this coin miner to connect your computer to a malicious cryptomining network. All these changes shall be thrown back to the original in the process of computer recovery.
Hardware effects of coin miner activity
Besides decreasing your PC’s performance, running at peak level for long times may cause damage to your device and increase power expenses. Hardware elements are designed to easily get along with high load, but they are good with it only in case when they are in a good shape.
Small and well-protected CPU fan is quite hard to damage. Meanwhile, GPUs have large and easy-to-access rotors, which can be easily broke if touched while working, for example, by the user much earlier before the virus injection. Malfunctioning cooling system, together with the really high load caused by \’at.exe virus can easily lead to graphic processing unit failure3. GPUs are also tend to have increased wearing when utilized for cryptocurrency mining. It is surely an unwanted situation when the performance of your graphic card decreases on 20-30% only after 1-2 weeks of being exploited in such a way.
How did I get \’at.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 prevalent malevolent programs through “severe” viruses. Adware frequently acts as a carrier for \’at.exe malware infiltration: it shows you the banners, which contain a link to malware downloading. Yes, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. But the statistics say that around 30% of all malware spread through the malevolent banners are coin miners – and \’at.exe is right among them.4
The example of malicious banners you can see in the Internet
Another way you could get this thing on your computer is by downloading it from the dubious website as a part of a program. Users who spread hacked variants of well-known programs (which do not demand the license key) have small chances to make money. Thus, there is a very big lure to include malware to the final package of the hacked app and acquire a coin for each installation. Before blaming these individuals for hacking and malware distribution, ask yourself – is it alright to avoid buying the program in this manner? It is much cheaper to pay $20-$30 one time than to pay a much greater figure for antivirus software and new parts for your computer.
How to remove the \’at.exe miner from my PC?

Proper security tool should have high efficiency at scanning and also be lightweight – in order to make no problems with utilization even on weak systems.
