What is Matiex?
Matiex is a keystroke logger which is capable of taking screenshots, recording sound with the computer microphone and data saved in the system clipboard. Its users can receive logged data via Telegram, SMTP, FTP and Discord. Research shows that this keystroke logger can be purchased for US$25, $60, or $99 depending on the subscription plan.
Generally, cyber criminals attempt to deceive users into installing this software on their computers in order to steal sensitive information, which can then be misused to generate revenue.
A keylogger is a type of software that is often used by cyber criminals to monitor and record each keystroke typed on an infected computer's keyboard. In most cases, cyber criminals seek to steal information such as logins, passwords (and other credentials), credit card details, and other personal, sensitive details.
This particular keylogger can be used to take screenshots, access and use the computer microphone and steal data saved on the operating system clipboard. Therefore, cyber criminals behind Matiex can misuse stolen information and/or access other data to steal identities, personal accounts, make fraudulent purchases and transactions, and for other malicious purposes.
Additionally, Matiex is capable of generating fake message boxes (pop-ups) containing any text. It also includes a "self destruct" feature, which allows this keylogger to uninstall itself at a certain designated time. If there is any reason to suspect that Matiex or other malware of this type is installed on your computer, remove it immediately.
Having a computer infected with a keylogger can be the reason behind serious issues such as identity theft, monetary loss, loss of access to personal and important online accounts, etc.

Hakops, Amadey and Cheetah are some of examples of other malicious programs that function as keyloggers. In most cases, cyber criminals attempt to trick users into installing this software so that they can steal information and misuse it to generate as much revenue as possible.
There are many legitimate keyloggers on the web, however, in some cases, cyber criminals use them to monitor victims. I.e., legitimate keyloggers can be used for malicious purposes.
How did Matiex infiltrate my computer?
Research shows that cyber criminals use malspam email campaigns to deceive users into installing Matiex on their computers. I.e., they send emails that contain a malicious attachment, a Microsoft Office Excel document capable of installing Matiex, but only if users open it and enable editing/content (macros commands).
Malicious documents opened with Microsoft Office versions that were released before 2010 infect computers automatically without asking any permissions. Microsoft Office 2010 and newer versions include "Protected View" mode, which prevents malicious documents from installing malware automatically.
How to avoid installation of malware
You are strongly advised to ignore irrelevant emails that contain attachments or web links. Note that users often receive malspam campaign emails from unknown, suspicious addresses. The emails are often disguised as important and official as if sent from legitimate companies/organizations.
Furthermore, software and files should not be downloaded or installed via third party downloaders/installers, Peer-to-Peer networks, unofficial sites, unofficial pages, free file hosting sites, etc. Use official websites and direct links. It is also important to update and activate installed software only with tools or implemented functions that are designed by official software developers.
It is illegal to activate any licensed programs with 'cracking' tools. Finally, computers are safer when regularly scanned with reputable anti-spyware or antivirus software. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus 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 Combo Cleaner Antivirus 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:

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 Combo Cleaner Antivirus for Windows.
