What is Baldi.exe process?

Baldi.exe is a malicious process created by coin miner virus

As I have actually specified earlier, Baldi.exe is a coin miner trojan virus. The names of the .exe file can be diverse, however, the impacts are usually the same. Considering that coin miners focus on cryptocurrency mining, they use all possible hardware power of your desktop to perform this operation. This malware does not take note of the fact that you probably want to make use of your PC for other activities – it will constantly use over 80% of your processor power.

Baldi.exe – Extremely high CPU/GPU use

Besides CPU consumption, some of the coin miners additionally use GPU power for their tasks. In that instance, you will struggle even to see the mouse cursor moving – GPU is usually utilized on 100%. It is not as vital as CPU for system work, so Baldi.exe coin miner viruses do not waste time on trifles and utilize it all. It often can lead to bad results.

Shortly about cryptocurrency mining

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
  • High temperature of the device (for laptops)
  • 80-90% consumption of CPU/GPU resources by an unknown process

  • How dangerous is the Baldi.exe miner?

    Coin miners does not deal damage to your files. However, they make a lot of unpleasant things with the whole system

    First, Baldi.exe malware makes your system overloaded. It is unable to run your applications now, because all CPU power is used by a virus. That malware does not care for your demands, all it focuses on is making money on you. Even if you are patient, and you waited until browser is open, you will likely experience incredibly slow efficiency. Pages can open up for years, any type of logins will take about a minute – just a horror story for a person who works online.

    “Visible” harm is not a solitary bad thing coin miners do to your PC. Baldi.exe coin miner likewise deals damage to your OS. To conduct all malicious functions properly, it ruins the security features of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent detection. If you open the HOSTS file, you will likely see a lot of new entries – they are added by this trojan miner to connect your PC to a malicious mining network. All these changes are about to be gone back to the original in the process of computer recovery.

    Hardware effects of coin miner activity

    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.

    How to remove the Baldi.exe miner from my PC?

    The best way to get rid of this coin miner virus is to use anti-malware software

    Eliminating such a virus involves making use of specific software. Appropriate security tool should have high capability at scanning and be lightweight – in order to create no problems with utilization even on weak systems. On top of that, it is better to have on-run protection in your protection tool – to halt the virus even before it launches. Microsoft Defender lacks these functions for various reasons. That’s why I’d suggest you to use a third-party anti-malware program for that purpose. GridinSoft Anti-Malware is a perfect option that fits each of the mentioned qualities.4

    Before the virus removal, it is important to reboot your Windows into Safe Mode with Networking. Since Baldi.exe miner consumes a lot of CPU capacity, it is required to stop it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.

    Press the Start button, then choose Power, and click on Reboot while holding the Shift key on the keyboard.

    Boot into Windows Safe Mode

    Windows will reboot into recovery mode. In that mode, choose Troubleshoot→ Startup Settings→ Safe Mode with Networking. Press the corresponding button on your keyboard to choose that option.

    When your PC is in Safe Mode, all third-party software, just like the majority of non-critical system components, are not started with the system start. That allows you to clean the system without dealing with high CPU usage of the coin miner.
