In most cases, cyber criminals use malware of this type to steal sensitive information or proliferate other malware to enable them to generate revenue. Generally, users install malware on their computers inadvertently (they are tricked).
How did DarkStealer infiltrate my computer?
Malware is commonly spread using malspam campaigns, dubious file, software download channels/tools, third party software updating tools, unofficial activation ('cracking') tools and Trojans. Cyber criminals often send emails that are disguised as official/legitimate and contain a malicious attachment or website link.
Computers become infected with malware through dubious download channels when users open malicious files that were downloaded through them. These channels/tools are various unofficial pages, third party downloaders, free file hosting pages, freeware download sites, etc.
Note that third party installers can also be designed to install malicious software. Third party software updaters infect systems by installing malware rather than updates/fixes for installed software, or by exploiting bugs/flaws of outdated software that is installed on the computer.
Unofficial activation ('cracking') tools infect computers by installing malicious programs rather than activating the installed software.
People use these tools to activate licensed free of charge, however, they simply lead to problems. Trojans are malicious programs that can also install malware, thereby causing chain infections (they must already be installed on a computer to cause this issue).
How to avoid installation of malware
Website links, attachments in irrelevant emails should not be opened, especially if the emails are sent from unknown, suspicious addresses. Software should be downloaded only from official pages and through direct links. Other channels and tools such as unofficial pages, third party downloaders (and installers), etc., should not be used/trusted.
Furthermore, it is important to update and activate installed software properly using implemented functions and/or tools that are provided by official software developers. No unofficial, third party tools should be used. Furthermore, it is illegal to activate any licensed software with tools/programs of this kind.
Scan the operating system regularly for threats with reputable antivirus or anti-spyware software, that software, which should be kept up to date. 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.

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.
