Soltern virus removal guide
What is Soltern?
Soltern is a computer worm, a type of malware that copies itself for installation on other computers - it uses already infected systems as hosts to scan and infect the other machines. Typically, worms such as Soltern use computer networks, email services, instant messaging apps, and Peer-to-Peer (P2P) networks to proliferate. Soltern does not infect files, however, it might install other malware.
It is possible that Soltern might be used to infect computers with ransomware, Trojans (e.g, Remote Administration Trojans), cryptocurrency miners or other malware. Victims of ransomware attacks cannot access their files, since malware of this type encrypts them with a strong encryption algorithm. Typically, only the cyber criminals behind the ransomware have valid decryption tools/keys that can recover compromised files. Soltern might also be designed to distribute a RAT. When a computer is infected with a Remote Administration Trojan, the cyber criminal behind it can control the victim's device remotely. Usually software of this type allows cyber criminals to access files, steal login credentials (and other personal information), download and execute various files, take screenshots, access webcams and microphones, and perform other malicious actions. Furthermore, Soltern can be used to distribute and install a cryptocurrency miner. These programs use computer resources (GPU, CPU) to mine cryptocurrency. I.e., to solve complex mathematical problems. The main purpose of of these miners is to use other computers to generate revenue. Commonly, computers infected with cryptocurrency miners operate more slowly (or do not respond at all), consume more electricity. This software might also cause unexpected system crashes and shutdowns that can lead to permanent loss of unsaved data. In summary, Soltern can be the reason behind of installation of malicious software that can cause issues such as data/monetary loss, loss of sensitive information and files, issues relating to online privacy and browsing safety, identity theft, and other serious problems. Therefore, if there is a reason to suspect that Soltern is using a computer to spread itself on other machines, eliminate it immediately.
|Detection Names||ESET-NOD32 (A Variant Of Win32/GenKryptik.CMKB), Kaspersky (Trojan.Win32.Boht.akq), Microsoft (Trojan:Win32/Wacatac.C!ml), Symantec (ML.Attribute.HighConfidence), Full List (VirusTotal).|
|Payload||This worm could carry various payloads.|
|Symptoms||Worms are designed to stealthily infiltrate the victim's computer and remain silent, and thus no particular symptoms are clearly visible on an infected machine.|
|Distribution methods||Infected email attachments, malicious online advertisements, social engineering, software 'cracks'.|
|Damage||Installation of other malware, data theft, overloaded shared network.|
|Malware Removal (Windows)||
To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Malwarebytes.
Note that not all worms carry payloads. In some cases, their main purpose is to multiply and deplete system resources (such as hard drive space or bandwidth). Note that this malware can modify certain system settings to automatically run on each system startup.

How to avoid installation of malware
You are strongly advised to ignore irrelevant emails that contain attachments or web links, especially if the emails are received from unknown, suspicious addresses. Do not download or install software via third party downloaders/installers, Peer-to-Peer networks, unofficial sites, or the channels mentioned above. Use official websites and direct links. Update and activate installed software only with tools or implemented functions that are designed by official software developers. It is illegal to activate any licensed programs with 'cracking' tools. Regularly scan the system with reputable anti-spyware or antivirus software. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes 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 Malwarebytes 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 Malwarebytes for Windows.
