What is Lolbtg.exe process?

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

As I have actually mentioned previously, Lolbtg.exe is a coin miner trojan. The names of the executive file may be diverse, but the effects are generally the same. Considering that coin miners focus on cryptocurrency mining, they utilize all possible hardware power of your desktop to perform this procedure. This virus doesn’t take note of the fact that you probably want to use your machine for other tasks – it will consistently consume over 80% of your CPU power.

Lolbtg.exe – Really high CPU as well as GPU use

Besides CPU usage, some of the coin miners additionally make use of GPU power for their tasks. In that situation, you will probably struggle also to see the mouse arrow moving – GPU is often used on 100%. It is not as vital as CPU for system work, so Lolbtg.exe coin miner viruses don’t waste time on trifles and utilize all of it. It often may cause bad results.

Shortly about cryptocurrency mining

Crypto mining is a term that means the operation of calculating the transaction block hash. That is a integral part of any project based on the blockchain technology. Since this action takes a lot of calculations, a very powerful PC is needed. Exactly, the video card is better for this purpose, because they have more cores available. Cryptomining farms usually consist of dozens of GPUs to conduct their activity effectively. Such systems are not usable for “usual” purposes, like gaming or browsing the Web. Crooks 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
  • Microsoft Defender is not working
  • How dangerous is the Lolbtg.exe miner?

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

    Firstly, Lolbtg.exe virus makes your system overloaded. It is unable to run your applications now, since all CPU power is used by a virus. That malware does not care for your necessities, all it focuses on is generating income on you. Even if you are patient, and you waited until web browser is open, you will likely experience extremely sluggish performance. Pages can open for years, any sort of logins will take about a minute – just a nightmare for a person that does a job online.

    “Visible” harm is not a solitary negative activity coin miners do to your computer. Lolbtg.exe coin miner additionally deals damage to your OS. To perform all malicious functions correctly, it wrecks the protection 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 number of new notes – they are added by this trojan miner to connect your PC to a malicious cryptomining network. All these adjustments shall be reverted to the initial state in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides slowing down your computer, running at peak power for long times may cause damage to your device and raise power bills. Hardware elements are created to easily deal with high load, but they are good with it only when they are in a good shape.

    Compact and covered processor cooling system is hard to broke. Meanwhile, GPUs have big and easy-to-access fans, which can be easily cracked if touched while working, for example, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the really high load caused by Lolbtg.exe miner can easily lead to graphic processing unit failure3. Graphic cards are also prone to have increased wearing when used for cryptocurrency mining. It is surely a bad case when the performance of your graphic card plunges 20-30% just after 1-2 weeks of being used in such a way.

    How did I get Lolbtg.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 prevalent malevolent programs among “serious” malware. Adware sometimes acts as a carrier for Lolbtg.exe malware injection: it demonstrates you the banners, which contain a link to malware downloading. Sure, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. However, the statistics show that around 30% of all malware spread with the malevolent banners are coin miners – and Lolbtg.exe is right with them.4

    The example of malicious banners you can see in the Internet

    An additional way you could get this item on your PC is by downloading it from the unreliable site as a part of a program. Users that spread hacked variants of well-known programs (which do not need the license key) have small chances to get paid. Therefore, there is a huge lure to add malware to the final package of the hacked application and get a coin for each setup. Prior to blaming these guys for hacking and malware distribution, ask yourself – is it okay 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 sum for antivirus software as well as new parts for your PC.

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

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

    Removing such a virus demands the use of specific app. Effective anti-malware program should have high capability at scanning and also be lightweight – in order to create no problems with usage also on weak systems. Additionally, it is better to have proactive security in your security solution – to stop 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 goal. GridinSoft Anti-Malware is a superb option that fits all of the specified features.5

    Before the malware removal, it is important to reboot your Windows into Safe Mode with Networking. Since Lolbtg.exe miner consumes a lot of CPU power, it is required to halt 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 launched with the system start. That gives you the ability to clean the computer without dealing with high processor usage of the coin miner.
