This malware doesn’t pay attention to the fact that you may need to make use of your system for other tasks – it will constantly use over 80% of your processor power.

Shortly about cryptocurrency mining
Cryptocurrency mining is a term that means the operation of calculating the transaction block hash. That is a basic element of anything based on the blockchain technology. Since this operation takes a lot of calculations, a high-end desktop is required. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptocurrency mining farms are usually constructed of tens and hundreds of video cards to complete their task efficiently. Such computer 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

“Visible” damage is not a single unpleasant activity coin miners perform to your computer. Loleth.exe coin miner likewise deals damage to your OS. To complete all malevolent operations successfully, it wrecks the security mechanisms of your system. You will likely see your Microsoft Defender disabled – malware stops it to avoid recognition. If you open the HOSTS file, you will likely see a ton of new notes – they are added by this coin miner to connect your computer to a malicious mining network. All these adjustments are about to be reverted to the initial state in the process of system recovery.
Hardware effects of coin miner activity
Besides making your computer slow, running at peak level for a long period of time can trigger damage to your device and raise electricity costs. Hardware components are designed to easily deal with high load, but they are good with it only when they are in a good shape.
Small and well-protected CPU fan is not very easy to damage. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily broke if touched while running, for instance, by the user much earlier before the virus injection. Malfunctioning cooling system, together with the very high load caused by Loleth.exe can easily lead to GPU failure3.

It is surely an unwanted situation when the performance of your video card plunges 20-30% just after 1-2 weeks of being used in such a way.
How did I get Loleth.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 acts as a carrier for Loleth.exe malware injection: it shows you the banners, which have a link to malware downloading. Sure, this abstract “malware” can belong to any kind – yet another adware, spyware, rogue or backdoor. But the statistics show that about 30% of all malware spread through the malicious banners are coin miners – and Loleth.exe is just with them.4
The example of malicious banners you can see in the Internet
One more way you could get this item on your PC 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 need the license key) have small chances to earn money. Hence, there is a huge temptation to add malware to the final package of the hacked app and receive a coin for each installation. Prior to criticizing these people for hacking and also malware distribution, ask yourself – is it alright to avoid paying for the program in such a way? It is more affordable to pay $20-$30 at once than to pay a much greater figure for antivirus program as well as new parts for your PC.
