BitRAT virus removal guide
What is BitRAT?
BitRAT is a malicious program, classified as a RAT (Remote Access Trojan). Malware of this type is designed to enable remote access and control over an infected machine. RATs can have a wide variety of heinous functionalities. While BitRAT is by far not the most sophisticated piece of malicious software out there, nevertheless it is deemed to be highly dangerous. Therefore, BitRAT infections must be removed immediately upon detection. Since this trojan is offered for sale by its developers - how it is spread depends on the methods preferred by the cyber criminals who have purchased it.
As mentioned in the introduction, remote access trojans can have a wide variety of malicious features, which can enable varied level of control and abuse over the infected device. These trojans can have control over integrated/connected hardware, installed software and content stored in or accessed through the infected computer. According to BitRAT's promotional material, it is capable of controlling a machine's hardware thusly: employ the device's keyboard and mouse, possibly, move the mouse live / in real-time; via webcams and microphones record video and audio, as well as stream them live. BitRAT can manage the files stored in the system to a certain degree. It can exfiltrate and infiltrate (i.e. download and upload) files. The stolen data can then be used for ransom purpose. Furthermore, if the RAT's ability to execute uploaded files is successfully implemented - then it may be used to cause chain infections (i.e. to download/install additional malware). Similarly, BitRAT can stealthily use the browser (hidden/remote browser), specifically the Google Chrome browser. This malicious program can also extract stored log-ins credentials (i.e. IDs, usernames and passwords) from browsers and other applications. The promotional material states that the aforementioned feature of BitRAT is supported on over 35 browsers and more than 500 other different applications. This trojan has keylogging abilities, which means that it can record key strokes. Said feature is typically used to collect typed log-in credentials and other vulnerable data (e.g. names, addresses, telephone numbers, emails, banking account and/or credit card details, etc.). The BitRAT can function as a cryptominer as well, it is geared towards mining the Monero (XMR) cryptocurrency. Whilst BitRAT is a sloppily constructed malicious program with some of its functionalities being nonoperational and easily detectable - that does not negate the fact that its infections can lead to the victims experiencing financial loss, severe privacy issues and identity theft. Therefore, if it is suspected or known that BitRAT (or other malware) has already infected the system - an anti-virus must be used to eliminate it without delay.

How to avoid installation of malware?
Suspicious and/or irrelevant emails must not be opened, especially any links or attachments found in them - as that can result in a system infection. It is recommended to only use official and trustworthy download channels. Additionally, all products must be activated and updated with tools/functions provided by legitimate developers. Since illegal activation ("cracking") tools and third party updaters are often employed to proliferate malware. To ensure device integrity and user safety, it is paramount to have a dependable anti-virus/anti-spyware installed. Furthermore, this software myst be kept updated, used to perform regular system scans and to remove detected threats and issues. 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.
