More about the SaintStealer malware
SaintStealer terminates itself if it does not find any running processes after the execution. The same applies when it detects whether it is running in a sandbox or Remote Desktop Protocol (RDP) environment. Also, it checks for the installed antivirus software. It uses anti-reversing and evasion techniques to avoid analysis.
How did SaintStealer infiltrate my computer?
In most cases, threat actors use emails containing malicious attachments (or links) and cracked software download pages (or cracking tools) to distribute malware. They also use other unreliable sources for downloading software and files, certain Trojans, and fake updaters to distribute their malware.
In all cases, computers become infected after users execute malware by themselves. Examples of unreliable sources used to distribute malware are Peer-to-Peer networks, unofficial pages, third-party downloaders, and free file hosting pages.
How to avoid installation of malware?
Do not trust irrelevant emails received from suspicious/unknown addresses. Opening files or links in emails of this kind can result in computer infection. Keep the installed software up to date. Activate and update it with tools or functions provided by the official developers.
Download software (and files) from official websites. Always use direct download links. Use a reputable antivirus solution for computer protection. 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.
