Strigoi Master virus removal guide
What is Strigoi Master?
A Remote Access Trojan (RAT) is a malicious software that allows the attackers to monitor and control infected computers (or networks). They can open documents or any other files, download and install software, access webcam, microphone, etc. Usually, cybercriminals use RATs to infect computers with malware and (or) to obtain sensitive information that could be used for malicious purposes. Strigoi Master is written in Java programming language. It can be purchased on hacker forums, its monthly subscription costs $80, and its 3-month subscription costs $200.
Research shows that Strigoi Master can restart and shut down the infected machine, execute commands via Command Prompt and PowerShell, manage files (e.g., rename, delete, move, duplicate), log keystrokes (record keyboard input), download and execute various files. Usually, cybercriminals use the aforementioned features to download and install cryptocurrency miners, ransomware, or other malware. Also, they use them to obtain login credentials (usernames, email addresses, passwords), credit card details, bank account numbers, social security numbers, and other sensitive information. It is important to mention that they often use obtained credentials to steal personal accounts that could be used to send phishing emails, trick other users into making money transactions, make fraudulent transactions, purchases, and for other purposes. It is also possible that Strigoi Master could be used to access webcam and record videos that could be used to blackmail victims. In conclusion, Strigoi Master is RAT that can be the reason behind monetary and data loss, identity theft, loss of access to personal accounts, computer, problems with online privacy, and other issues. Users who suspect its presence should remove it from the operating system immediately.

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Malwarebytes.
There are many different RATs. Some examples are ObliqueRAT, Elephant RAT, Orcus RAT, ViperSoftX RAT. It is common that the attackers have anonymous control over infected computers - victims are not aware that they have a RAT installed on their machines. It is worthwhile to mention that RATs can be used to perform DDoS attacks and the infected network as a proxy server for fraudulent activities. In one way or another, when there is any reason to suspect that a system is infected with a RAT, then it should be scanned with a security suite, and all detected threats should be removed as soon as possible.
How did Strigoi Master infiltrate my computer?
Trojans can be designed to open function as backdoor malware. Once they are injected into the system, they can start causing chain infections/installing additional malware. Fake updaters, if used, cause damage in one of these ways: by installing malicious programs instead of updating, fixing installed programs, or by exploiting bugs, flaws of installed programs that are not up to date. Software 'cracking' tools are illegal programs that are supposed to activate licensed software (bypass its activation). Sometimes these tools work as they are expected to, however, not always. It is common for them to be bundled with malware.
How to avoid installation of malware?
Received emails that are not relevant, and sent from suspicious addresses should be ignored. Especially if these emails have some file attached to them, or include a website link. Very often, such emails are used by cybercriminals as channels to deliver malicious programs. Programs (and files) should be downloaded from legitimate, reliable sources such as official websites and direct links. It is not safe to open downloads that came from unofficial pages, third party downloaders, Peer-to-Peer networks, free file hosting sites, and so on. Moreover installed software has to be updated or activated with tools or using functions that the official developers provide (have designed). Third-party activation or updating tools tend to be used to trick users into installing malware - those tools often are bundled with malicious software. Another problem with unofficial tools that are supposed to activate software is that it is not legal to use them to activate software. One more way to protect computers is to scan them with a reputable antivirus or anti-spyware software. It is to run system scans 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 - 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:

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.
