Butler Miner Trojan
Butler Miner Trojan is a malicious application that might only bring problems to you. Specifically speaking, it might be the reason why your computer’s speed has decreased so dramatically and you can no longer use it normally. As the name of Butler Miner Trojan suggests, it is another miner. It seems that it has been developed by cyber criminals to mine a popular cryptocurrency called Monero. Like many other Trojans, it enters users’ computers illegally and then immediately starts doing its dirty job on them. Of course, it performs all its activities secretly in the background in order not to be detected and removed. Unlike ordinary programs, it does not have an interface too, so it is not surprising at all that it takes time for users to detect this infection on their computers. Usually, they realize that there is a malicious application active on their systems when their machines become very sluggish. If your PC has become as slow as a turtle too, we recommend that you open your Task Manager and check all active processes there – you should be able to find the process of Butler Miner Trojan listed there if it is really active on your system. This Trojan infection should also create an entry/entries in the Run registry key so that it could launch with every start of the infected machine. If it turns out that this infection is installed, do not wait until tomorrow – erase it from your system as soon as possible.
Interestingly, Butler Miner Trojan uses XMRig Miner as a script and injects it into the explorer.exe process (the process is 100% legitimate) on the affected computer. Then, it starts mining cryptocurrency. As mentioned, it should focus on mining Monero, but, technically, it can be used to mine other cryptocurrencies too. It needs power to mine cryptocurrency, so it uses CPU and GPU resources of affected computers. Owners of brand new computers might not notice anything strange, but if you use an older machine, it is only a question of time when it will become extremely sluggish. The decreased speed of the computer is not the only problem Butler Miner Trojan causes. Your computer might also start freezing from time to time. In other words, you could no longer use it normally. Luckily, everything will get back to normal once Butler Miner Trojan is removed from the system, so we highly recommend that you eliminate it ASAP. Theoretically, other harmful malicious applications might infiltrate your computer too with the help of Butler Miner Trojan, so the sooner you disable it, the better. Unfortunately, we cannot promise that its removal will be a piece of cake.
Since you already know more about Butler Miner Trojan, we should now talk about its distribution. According to our malware analysts, it is very likely that this malicious application imitates Magic Disk, which is a virtual disk creation program; however, there are no guarantees that it cannot be disguised as another useful application, for example, a key generator. Because of this, it is advisable not to download any applications from suspicious file-sharing websites and torrents. You should download software only from its official website or a 100% reliable source. What else security specialists recommend for users is staying away from suspicious/spam emails because malware might be distributed as an email attachment as well. Unfortunately, sneaky malware might still try to infiltrate your computer no matter how careful you are. Because of this, you should also have a security application enabled on your PC. It will make sure no harmful threats have a chance to enter the system illegally.
Butler Miner Trojan is not the simplest malicious application. It should even create a point of execution to be able to start working on system startup, so its removal might not be the easiest task at all. The first thing you should do is killing all suspicious processes in Task Manager. Then, you should check the Run registry key. If any suspicious entries are found, they must be removed ASAP. Finally, you will need to remove malicious files associated with this Trojan infection from your system. If you decide to erase Butler Miner Trojan manually, our instructions (see below) will surely help you, but it would be best that you use an antimalware scanner to clean your system if you are not very experienced in malware removal.
