LuxNET malware removal guide
What is LuxNET?
LuxNET is a Remote Administration/Access Trojan (RAT), a piece of malware that cyber criminals use to control infected computers remotely. As a rule, they use RATs to steal sensitive, confidential information and/or infect computers with some other malicious software. It is common that RATs are difficult to detect, which means cyber criminals can use them for malicious purposes for an undetermined amount of time.
In most cases cyber criminals can use RATs like LuxNET to access confidential, sensitive information such as credit card details, login credentials (usernames, email addresses, passwords), and other data of this kind. In most cases RATs steal such data either by logging keystrokes (recording keyboard input) or by using some other spying technique/feature. Also, RATs often are capable of enabling webcam and/or microphone and recording video and/or audio. It is common that cyber criminals use recorded material to blackmail victims - they threaten do send it to other people, publish on some website, etc., and demand to be paid for not doing so. It is worthwhile to mention that malware of this type can be capable of taking screenshots as well. Furthermore, cyber criminals often use RATs to infect computers with other malware, for example, ransomware, a Trojan other kind. Another capability that many RATs have is file managing: they can be used to delete, modify, rename, and manage files in other ways. Therefore, users who have their computers infected with LuxNET (or other RAT) can become victims of identity theft, suffer monetary, data loss, lose access to various personal accounts, have their computers infected with some other malware, and experience other, serious problems.

How to avoid installation of malware?
Emails that are received from unknown, suspicious addresses, have some files attached to them or contain website links should not be trusted. It is common that by opening files or links in them recipients cause installation of some malicious software. Installed software has to be updated and/or activated with implemented functions or tools that are provided by its official developers. Third party, unofficial tools should never be used neither to update or activate any software. Besides, it is not legal to use such tools to activate licensed programs. Furthermore, files or programs should not downloaded via untrustworthy, unofficial websites, through third party downloaders or other sources, tools of this kind. The only safe way to do it is by using official websites and direct links. It is worthwhile to mention that third party installers should never be used too. One more way to keep computers safe is to regularly scan them with reputable anti-spyware or antivirus and always keep it 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.

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.

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.
