Besides CPU consumption, some of the coin miners additionally use GPU power for their tasks. In that case, you will likely struggle also to see the mouse cursor moving – GPU is usually utilized on 100%. It is not as crucial as processor for system work, so Retrogui coin miner viruses do not waste time on trifles and use all of it. It sometimes may lead to sad consequences.
Shortly about cryptocurrency mining
Crypto mining is a term that means the action 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 very strong desktop is required. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptomining farms usually consist of tens and hundreds of graphic cards to conduct their activity effectively. Such systems are not usable for “usual” purposes, like gaming or web browsing. Fraudsters who make profit via this coin miner use someones’ hardware instead, even if they are used for the regular activity.2

To execute all malicious functions successfully, it ruins the protection components of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent recognition. If you check the HOSTS file, you will likely see a number of new notes – they are brought in by this coin miner to connect your computer to a malicious cryptomining network. All these changes shall be thrown back to the initial state in the process of computer recovery.
Hardware effects of coin miner activity
Besides decreasing your system’s performance, running at peak power for long times may trigger damage to your machine and raise electricity expenses. PC 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.
Compact and well-protected CPU fan is not very easy to crack. Meanwhile, graphic cards have big and easy-to-access fans, which can be easily cracked if affected while spinning, for instance, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the extremely high load caused by Retrogui can easily lead to graphic processing unit failure3. Graphic cards are also tend 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% just after 1-2 weeks of being used in such a way.
How did I get Retrogui 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 “major” malware. Adware sometimes acts as a carrier for Retrogui malware infiltration: it shows you the banners, which contain 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 about 30% of all malware spread with the malevolent banners are coin miners – and Retrogui is just with them.4
The example of malicious banners you can see in the Internet
One more way you could get this thing on your computer is by downloading it from the unreliable website as a part of a program. Users that spread hacked variants of favored programs (which do not demand the license key) have small chances to make money. Hence, there is a huge temptation to add malware to the final package of the hacked application and receive a coin for each setup. Prior to criticizing these guys for hacking and malware spreading, ask yourself – is it OK 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 figure for antivirus software and new parts for your computer.
