How to eliminate ModernLoader malware from the operating system
Written by Tomas Meskauskas on
What is ModernLoader?
ModernLoader, also known as Avatar Bot and AvatarLoader, is a malicious program that has minimalistic loader and RAT (Remote Access Trojan) functionalities.
Loader-type malware is designed to infect devices with additional malicious programs, while RATs enable remote access/control over infected machines. ModernLoader is capable of executing basic commands and injecting malicious modules into systems.
ModernLoader malware overview
As mentioned in the introduction, ModernLoader can perform a set of basic commands on infected devices. It also collects device-related data, e.g., operating system version, CPU, RAM, available disk space, account type (admin/user), IP address, installed security tools, etc.
ModernLoader is capable of downloading and executing files. Hence, this program can inject various malicious modules into systems, which could possess data-stealing, spying, or other functions.
Researchers at Cisco Talos Intelligence Group have noted ModernLoader campaigns infiltrating crypto-mining modules into devices. Cryptocurrency mining is the action of using system resources to generate cryptocurrency; malicious cryptominers can abuse said resources to the point of causing system failure and even hardware damage.
Previously observed ModernLoader campaigns also involved the XMRIG cryptominer, RedLine Stealer, SystemBC malware, and DarkCrystal RAT.
To summarize, the presence of malware like ModernLoader on devices may lead to multiple system infections, data loss, severe privacy issues, hardware damage, financial losses, and identity theft.
If you suspect that your system is infected with ModernLoader (or other malware), we strongly recommend using an anti-virus to remove it without delay.

Similar malware examples
We have inspected thousands of malware samples, e.g., IceXLoader, Nitrokod, GootLoader are a few loader-type programs, and TigerRAT, MagicRAT, VanillaRAT - remote access trojans which we have analyzed recently.
Malicious software can have a wide variety of functionalities - however, it is usually used for the same purpose - to generate revenue. Regardless of how malware operates, its presence endangers device integrity and user safety. Therefore, all threats must be eliminated immediately upon detection.
How did ModernLoader infiltrate my computer?
Malware is proliferated using phishing and social engineering tactics. Malicious programs are usually presented as or bundled with ordinary software/media.
The most common malware distribution techniques include: drive-by (stealthy and deceptive) downloads, online scams, untrustworthy download sources (e.g., freeware and third-party websites, Peer-to-Peer sharing networks, etc.), illegal program activation tools ("cracks"), malicious attachments/links in spam emails and messages, fake updates, and malvertising.
How to avoid installation of malware?
We highly recommend downloading from official and verified channels. Additionally, all programs must be activated and updated using tools provided by legitimate developers, as illegal activation tools ("cracks") and fake updates may contain malware.
We advise against opening the attachments and links present in suspicious/irrelevant emails and messages since that can result in a system infection.
It is essential to have a reputable anti-virus installed and kept updated. This software must be used to perform regular system scans to remove threats and issues. 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.

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, be sure to 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.
