What is SamoRAT?
SamoRAT is a Remote Access Trojan (RAT), a type of malware that allows the cyber criminals responsible to monitor and control the infected computer. In most cases, RATs are used to steal sensitive information and/or install other malware onto the infected computer. In any case, RATs are used for malicious purposes and can be the reason behind serious problems.
Research shows that SamoRAT allows cyber criminals to execute files stored on computers or downloaded from the internet, capture the screen, steal passwords saved on the Chrome browser, shutdown and restart computers, and open various websites.
SamoRAT can also be added to system startup, updated and uninstalled, and is capable of bypassing the User Account Control (UAC) mandatory access control enforcement facility. Additionally, this RAT can mine cryptocurrency.
By stealing passwords saved on Chrome, cyber criminals can misuse the information to hijack/steal various accounts (e.g., banking, email, social media and other accounts), which can then be misused to make fraudulent purchases and transactions, steal identities, spread malware, trick other people into making financial transactions, etc.
A cryptomining feature allows cyber criminals to mine cryptocurrency using infected computers' hardware (CPU, GPU). Therefore, infected machines might operate at reduced speed (or not respond at all), consume more electricity, etc. Therefore, users might experience unexpected shutdowns (which could result in loss of unsaved data) and receive higher electricity bills.
Furthermore, high CPU and/or GPU usage can cause hardware to overheat. These are the main issues with having computers infected with SamoRAT. If there is any reason to believe that this RAT is installed on your computer, remove this malware immediately.

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Combo Cleaner.
There are many other RATs on the internet. Some examples are XpertRAT, STRRAT and Bozok. As mentioned, cyber criminals attempt to infect users' computers with this malware to steal sensitive information and install additional malware. Having a computer infected with a RAT can cause serious problems.
Ways to avoid installation of RATs and other malware are described below.
How did SamoRAT infiltrate my computer?
Most cyber criminals attempt to proliferate malicious software through spam campaigns, Trojans, unofficial updaters, software 'cracking' tools (activators) and untrusted file/software download channels. They send emails that contain malicious attachments or website links.
Therefore, when a computer is infected with a Trojan, it can become infected with other malware as well. Fake software updaters cause damage by installing malicious software rather than updates/fixes, or by exploiting bugs/flaws of outdated programs. Various unofficial activators, which supposedly activate licensed free of charge, often infect computers with malware instead.
Peer-to-peer (P2P) networks, free file hosting websites, freeware download pages, third party downloaders and other similar channels are also used to distribute malware. Cyber criminals disguise malicious files as regular/legitimate and wait for users to download and open them. When opened, they install high-risk malware onto users' computers.
How to avoid installation of malware
You are strongly advised to ignore irrelevant emails that contain attachments or web links, especially if they are received from unknown, suspicious addresses. Commonly, these emails are disguised as important, official, and so on. Do not download or install software/files through unofficial pages, third party downloaders (or installers) or the other tools/channels mentioned above.
All software and files should be downloaded from official websites and direct links. Update and activate installed software through implemented tools/functions provided by official developers. Other unofficial, third party tools should never be used. Furthermore, it is illegal to activate licensed software using unofficial activators ('cracking' tools).
Regularly scan your computer for threats with reputable anti-spyware or antivirus software. 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.
