SamoRAT virus removal guide
What is SamoRAT?
SamoRAT is a Remote Access Trojan (RAT), a type of malware that allows cyber criminals behind it to monitor and control the infected computer. In most cases RATs are used to steal sensitive information and/or install some other malware on the infected computer. Either way, RATs are used for malicious purposes and can be the reason behind a variety of problems.
Research shows that SamoRAT allows cyber criminals to execute files stored on a computer or downloaded from the Internet, capture screen, steal passwords saved on Chrome browser, shutdown, restart a computer and open various websites. Also, SamoRAT can be added to system startup, updated, uninstalled and it is capable of bypassing the UAC (User Account Control) mandatory access control enforcement facility. Additionally, this RAT can mine cryptocurrency. Basically, cyber criminals behind SamoRAT can use it as a tool to infect a computer with some other Trojan, ransomware, or other malicious software that could be used as a tool to generate revenue in one or another way. By being able to steal passwords saved on Chrome cyber criminals may misuse them to hijack/steal various accounts (e.g., banking, email, social media and other accounts) that could be misused to make fraudulent purchases, transactions, steal identities, spread malware, trick other people into making money transactions, etc. Crypto mining feature allows cyber criminals to use infected computers to mine cryptocurrency by using their hardware (CPU, GPU). It means that infected machines may operate slower (or not respond at all), consume more electricity, which means users may experience unexpected shutdowns (which could result in loss of unsaved data), receive higher electricity bills. Also, high CPU and/or GPU usage may cause hardware overheat. These are the main issues with having a computer infected with SamoRAT. If there is any reason that this RAT is installed on a computer, then this malware should be uninstalled as soon as possible.

How to avoid installation of malware?
It is strongly recommended to ignore irrelevant emails that contain attachments or web links, especially if they are received from unknown, suspicious addresses. It is common that such emails are disguised as important, official, and so on. Also, it is important not to download (or install) software or files through from unofficial pages, third party downloaders (or installers), or any other tools, channels that are mentioned in the previous paragraph. All software (and files) should be downloaded from official websites and direct links. The safest and the only proper way to update or activate installed software is to use tools or implemented functions that are provided/designed by official developers. Other (unofficial, third party) tools should never be used. Besides, it is not legal to activate any licensed software unofficial activators ('cracking' tools). One more important thing is to regularly scan a computer for threats with a 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.

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.
