As I have specified in the introduction, Light.exe is a coin miner trojan. The names of the .exe file may be different, but the impacts are usually the same. Considering that coin miners aim at cryptocurrency mining, they utilize all available hardware power of your PC to run this operation.

It is not as vital as CPU for system work, so Light.exe coin miner viruses do not waste time on trifles and use all of it. It sometimes may cause unhappy consequences.
Shortly about cryptocurrency mining
Crypto mining means the operation of calculating the transaction block hash. That is a basic part of any project based on the blockchain technology. Since this operation takes a lot of calculations, a very strong desktop 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 complete their task efficiently. Such systems are not usable for “normal” purposes, like gaming or browsing the Web. Fraudsters who gain money via this coin miner use someones’ PCs instead, even if they are used for the regular activity.2

“Visible” damage is not a solitary unpleasant thing coin miners do to your PC. Light.exe coin miner additionally deals damage to your OS.

If you open 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 mining network. All these adjustments are about to be thrown back to the original in the process of system recovery.
Hardware effects of coin miner activity
Besides decreasing your computer’s performance, running at peak power for long times can trigger damage to your machine as well as raise power expenses. Hardware components are created to easily deal with high load, but they can do so only in case when they are in a good shape.
Little and covered CPU cooling system is hard to broke. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily broke if affected while running, for instance, by the user much before the virus injection. Malfunctioning cooling system, together with the really high load caused by Light.exe malware can easily lead to graphic card failure3. GPUs are also tend to have very fast wearing when used for cryptocurrency mining. It is surely an unwanted case 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 Light.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 through “serious” malware. Adware often functions as a carrier for Light.exe malware injection: it shows you the banners, which include a link to malware downloading. Yes, this abstract “malware” can belong to any kind – yet another adware, spyware, rogue or backdoor. However, the statistics say that about 30% of all malware spread with the malicious banners are coin miners – and Light.exe is right one of them.4
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 versions of favored programs (which do not demand the license key) have small chances to get paid. Thus, there is a very big lure to add in malware to the final package of the hacked application and get a coin for every installation. Prior to blaming these guys for hacking and malware distribution, ask yourself – is it alright to avoid paying for the program in this manner? It is much cheaper to pay $20-$30 one time than to pay a much bigger figure for antivirus program and new parts for your computer.
