DarkRAT virus removal guide
What is DarkRAT?
DarkRAT is one of many remote access tools (RATs) used to control connected computers remotely. Unfortunately, in many cases, cyber criminals trick people into installing RATs onto their systems and then use them to steal personal details, infect systems with malware, and cause other damage. If your system is infected with this RAT, we strongly recommend that you uninstall it immediately.
One DarkRAT feature prevents users from killing its process. Therefore, it cannot be disabled and will run in the system background. Cyber criminals can then use its features when they wish. Additionally, it can prevent victims from removing it from the list of startup items. I.e., it can then launch itself at each startup automatically. Furthermore, DarkRAT can be used to download and execute various files onto the victim's computer. Typically, cyber criminals download and execute malicious files that infect the system with malware. For example, ransomware, which encrypts files and prevents victims from accessing them. Typically, the only way to decrypt data is to purchase decryption software and/or keys from the cyber criminals who designed the ransomware. Note that ransomware is not the only malware that can be installed through DarkRAT. This remote access tool is also capable of updating itself. As soon as a newer version is released, it starts to update itself. Furthermore, cyber criminals can remotely load custom DLL files onto the victim's computer and affect behaviour of the operating system or installed programs. They can also use it to check which anti-virus software is installed on the operating system and then avoid detection.

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Malwarebytes.
WSH, InnfiRAT, and Gh0st are just a number examples of other RATs that cyber criminals use to control users' computers remotely. Their aim is to steal personal details (logins, passwords of various accounts), install additional malware, and perform other actions. Being tricked into installing software of this type can lead to serious problems.

How to avoid installation of malware
Do not open web links or files that are attached to irrelevant emails, especially if the emails are received from unknown, suspicious addresses. If there is reason to believe that an email is suspicious, the best option is to leave included links or files unopened. Furthermore, download software from official, trustworthy sources websites. All channels mentioned above should not be trusted. All installed software must be updated through tools or implemented functions that are provided by official developers. Licensed/paid programs should not be activated using unofficial ('cracking') tools. This is illegal and often leads to installation of malware. Keep computers safe by having reputable anti-spyware or anti-virus software installed. Scan systems regularly. 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 - it is usually 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 the "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.
