Removing MyloBot malware from the operating system
Written by Tomas Meskauskas on (updated)
What is MyloBot?
MyloBot is a high-risk trojan-type virus that allows cyber criminals to control the infected machine. MyloBot can be considered as a botnet, since all infected computers are connected to a single network. Depending on cyber criminals' goals, infected machines might be misused or have additional infections applied.
MyloBot malware overview
Immediately after infiltration, MyloBot scans the "Application Data" folder to check for other malware infiltration and whether the software is running. If found, the malware is immediately terminated and deleted. MyloBot probably does this to fight competition - multiple viruses might interfere and affect the behavior and efficiency of the infiltrating software.
Ultimately, this could lead to inaccuracies and unexpected computing results. Therefore, criminals aim to take over the computer exclusively. As mentioned above, the presence of the MyloBot virus might lead to various problems, depending on the developer. Cyber criminals generate revenue by selling traffic.
The entire botnet (infected machines) can be used to perform various connections. For example, criminals can increase website traffic by forcing infected computers to visit certain URLs. The botnet can also be used to perform DDoS attacks. Infected computers can be used to do perform many unwanted tasks such as this.
For example, criminals can download and install other viruses (such as ransomware, password-stealers, cryptominers, etc.) onto the system.
Therefore, the presence of this malware can lead to serious privacy issues, and significant financial and data losses. System performance is very likely to be significantly affected. If you suspect that your computer is infected with the MyloBot trojan, immediately scan it with a reputable anti-virus/anti-spyware suite and eliminate all threats.

Similar malware examples
Many trojan-type viruses share similarities with MyloBot. For example, Adwind, Hancitor, TrickBot, etc. As compared to these trojans, MyloBot is much more sophisticated, since it is capable of performing multiple tasks. Regular trojans generally just record sensitive data, cause chain infections, or similar. Nevertheless, all pose a high risk to your privacy and computer safety. Eliminating them immediately.
How did MyloBot infiltrate my computer?
It is currently unknown exactly how MyloBot is distributed, however, this malware is capable of detecting whether it is executed in a virtual machine and/or a sandbox. These viruses are often distributed using trojans, spam email campaigns, peer-to-peer (P2P) networks, third party software download sources, and fake software updaters.
Trojans cause chain infections (one virus proliferates another). Spam campaigns proliferate malicious attachments that, once opened, download and install malware onto the system. P2P networks (eMule, torrents, and so on) and other unofficial download sources (free file hosting websites, freeware download websites, etc.) present malicious executables as legitimate software.
Therefore, users are tricked into downloading and installing viruses. Fake update tools infect the system by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than updates.
How to avoid installation of malware?
To prevent this situation, be very cautious when browsing the Internet and downloading/installing/updating software. Think twice before opening email attachments. If the file is irrelevant or the sender is unrecognizable, do not open it. Furthermore, avoid using third party downloaders/installers, since developers monetize them by promoting rogue apps.
Software should be downloaded from official sources only, using direct download links. The same applies to software updates. Keep installed applications up-to-date, however, this should be achieved through implemented functions or tools provided by the official developer only.
Have a reputable anti-virus/anti-spyware suite installed and running, since these tools can detect and eliminate malware before it does any damage. The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution.
If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.
Update February 15, 2022 - Botnets created using MyloBot have been observed being used for sextortion spam campaigns. These spam emails allude to the recipient's preferences in adult content (e.g., pornography) and make false claims about an explicit recording made while they were watching said content. The letters then threaten to leak the nonexistent videos - unless the recipient pays a ransom.

How to remove malware manually?
Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically.
To remove this malware we recommend using Combo Cleaner Antivirus for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
If you checked the list of programs running on your computer, for example using task manager, and identified a program that looks suspicious, you should continue with these steps:
Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:
Restart your computer into Safe Mode:
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs.
These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
