ExpertRAT virus removal guide
What is ExpertRAT?
ExpertRAT is a piece of malware which functions as a Remote Administration/Access Trojan (RAT). It allows cyber criminals to control infected machines (computers) remotely. Research shows that cyber criminals behind ExpertRAT target users living in Italy. This RAT was discovered by reecDeep. If there is any reason to suspect that a computer is infected with ExpertRAT, then this malware should be uninstalled from it as soon as possible.
In most cases RATs like ExpertRAT can be used to take screenshots of victim's screen, access webcam, download and execute files, execute commands, log keystrokes, manage (delete, rename, modify, etc.) files stored on a computer, and for other purposes. Therefore, cyber criminals can use malware of this type to steal sensitive information like usernames, passwords of various accounts, credit card details, access personal, confidential documents or other data, install some other malware (e.g., ransomware, Trojan) on the infected computer, etc. In other words, users who would have ExpertRAT installed on the operating system may become victims of identity theft, lose access to various personal accounts (e.g., email, social media, banking accounts), have their computers infected with more malicious programs that could be used for other malicious purposes, suffer monetary, data loss, experience serious problems related to online privacy, browsing safety, etc. It is worthwhile to mention that it is common for RATs to be designed to run in the background silently, therefore, victims may not know that such malware is installed on their computers for indefinite amount of time.

How to avoid installation of malware?
Files attached to irrelevant emails that are received from unknown, suspicious addresses should not be opened. It is worthwhile to mention that cyber criminals disguise their emails as official, important, etc. Website links and attachments in received emails should be opened only when there is not reason to suspect that it could be not safe. All software (and files) should be downloaded from official, trustworthy websites. Any other sources should not be trusted (examples of unreliable download sources, channels are provided in the previous paragraph). Furthermore, installed programs must be updated and/or activated with tools and/or functions that are provided by their official developers, and not some third party, unofficial tools. Moreover, it is not even legal to use 'cracking' (unofficial activation) tools to bypass activation of licensed software. And finally, it is important to regularly scan the operating system for threats with a reputable antivirus or anti-spyware software and always keep that software up to date. 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.
