How to remove PSLoramyra loader-type malware from the operating system
Written by Tomas Meskauskas on
What kind of malware is PSLoramyra?
PSLoramyra is a loader-type malware. Programs within this classification are designed to cause chain infections, i.e., download/install additional malware or malicious components. PSLoramyra is a rather sophisticated loader; it is considered a file-less malware since it executes its payload directly in memory.
PSLoramyra malware overview
PSLoramyra is a type of malware designed to introduce additional payloads into compromised systems. Its infection process is classed as "file-less" since the supplementary malicious content is executed in memory. This loader relies on PowerShell, VBS, and BAT scripts to infiltrate its payload.
PSLoramyra's infection process is geared towards detection evasion. The chain begins with a PowerShell script, which includes the primary payload and the scripts necessary for its execution. This malware also ensures persistence by executing a VBScript designed to run other scripts, thus ensuring the progression of the infection chain. This script is run every two minutes via Windows Task Scheduler.
As mentioned, PSLoramyra executes its payload directly in memory. In a brief overview, the process involves the introduction of a .NET assembly, wherein the called Execute method is injecting the malicious code into a legitimate process.
In one of the known PSLoramyra attacks, the targeted process was RegSvcs.exe – a Microsoft component for registering and configuring components associated with the .NET Framework. One of the variable strings contains the injector for the .NET assembly, which is intended to introduce the main payload into a genuine process (e.g., RegSvcs.exe).
Theoretically, loader malware can cause just about any type of infection – ranging from trojans to ransomware. However, in practice, these programs tend to operate within certain limitations. Several loaders can be used in succession, with each serving as but a part of a greater chain.
The threats associated with such infections depend on the capabilities of the loader and the malware they load, as well as the attackers' goals. Generally, malicious software of this kind is associated with multiple system infections, data loss, severe privacy issues, financial losses, and identity theft.

Loader-type malware examples
We have investigated countless malicious programs; GodLoader, JinxLoader, and BabbleLoader are but a few of our latest articles on loaders.
Malware is a broad term encompassing software with various malicious functionalities. Yet regardless of how a program within this classification operates – its presence on a system threatens device integrity and user safety. Therefore, all threats must be eliminated immediately upon detection.
How did PSLoramyra infiltrate my computer?
Malware is predominantly spread using phishing and social engineering tactics. Malicious programs are usually disguised as or bundled with ordinary content.
Virulent files come in various formats, e.g., executables (.exe, .run, etc.), archives (RAR, ZIP, etc.), documents (Microsoft Office, Microsoft OneNote, PDF, etc.), JavaScript, and so on. Merely opening such a file can be enough to initiate the infection chain.
Malware is primarily proliferated via drive-by downloads, online scams, malicious attachments/links in spam (e.g., emails, PMs/DMs, social media posts, etc.), malvertising, dubious download channels (e.g., freeware and free file-hosting sites, P2P sharing networks, etc.), fake updaters, and illegal software activation tools ("cracks").
Furthermore, some malicious programs can self-spread through local networks and removable storage devices (e.g., external hard drives, USB flash drives, etc.).
How to avoid installation of malware?
It is crucial to be careful while browsing since fraudulent and malicious online content usually appears genuine and harmless. We recommend treating incoming emails and other messages with caution. Attachments or links present in suspect/irrelevant mail must not be opened, as they can be virulent.
Another recommendation is to download only from official and verified sources. Additionally, all programs must be activated and updated using genuine functions/tools, as those obtained from third-parties may contain malware.
We must stress the importance of having a reputable anti-virus installed and kept up-to-date. Security software must be used to run regular system scans and to remove detected 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.

Windows 8 users: Start Windows 8 is Safe Mode with Networking - Go to Windows 8 Start Screen, type Advanced, in the search results select Settings. Click Advanced startup options, in the opened "General PC Settings" window, select Advanced startup.
Click the "Restart now" button. Your computer will now restart into the "Advanced Startup options menu". Click the "Troubleshoot" button, and then click the "Advanced options" button. In the advanced option screen, click "Startup settings".
Click the "Restart" button. Your PC will restart into the Startup Settings screen. Press F5 to boot in Safe Mode with Networking.

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.
