Cryptocurrency mining means the action of calculating the transaction block hash. That is a basic element of anything based on the blockchain technology. Since this action takes a lot of calculations, a strong desktop is required. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptocurrency mining farms are usually constructed of dozens of video cards to complete their task efficiently. Such systems are not usable for “normal” 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

List of the typical coin miner symptoms

  • Extremely bad performance
  • CPU/GPU cooler fan creates a lot of noise

    Besides decreasing your computer’s performance, running at peak level for a long period of time may cause damage to your device as well as raise electricity expenses. Hardware components are designed to easily get along with high load, but they can do so only when they are in a good shape.

    Little and well-protected CPU fan is quite hard to broke. Meanwhile, graphic cards have big and easy-to-access fans, which can be easily cracked if touched while running, for instance, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the unusually high load caused by Baldi.exe can easily lead to GPU failure3. Graphic cards are also prone to have very fast wearing when utilized for cryptocurrency mining. It is surely an undesirable situation when your GPU’s performance plunges 20-30% only after several weeks of being exploited in such a way.

    How did I get Baldi.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 widespread malevolent programs among “major” malware. Adware frequently acts as a carrier for Baldi.exe malware infiltration: it demonstrates you the banners, which contain a link to malware downloading. Yes, this abstract “malware” can belong to any kind – another adware, spyware, rogue or backdoor. But the statistics say that around 30% of all malware spread through the malicious banners are coin miners – and Baldi.exe is just one of them.

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    Another way you could get this item on your computer is by downloading it from the unreliable web page as a part of a program. Users who spread hacked variants of favored programs (which do not need the license key) have small chances to earn money. Therefore, there is a very big lure to add in malware to the final package of the hacked application and acquire a coin for each installation. Prior to blaming these guys for hacking and malware distribution, ask yourself – is it okay 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 bigger figure for antivirus program as well as new parts for your PC.
