More about info stealers

There are many different information stealers with different capabilities. A couple examples of information-stealing malware are RisePro Stealer, PureLogs Stealer, and CodeRAT Stealer. Malware of this type can be capable of logging keystrokes (recording keyboard input), capturing screenshots, exfiltrating clipboard data, and more.

How did StealDeal infiltrate my computer?

StealDeal is delivered via email (a compromised email address) containing a PDF document. That document contains a link to a web page hosting a ZIP archive containing an executable file ("certificates_rootCA.exe") that drops StealDeal and FateGrab. Users infect computers by executing that file.

How to avoid installation of malware?

Do not open links and attachments received via email without examining letters. Note that irrelevant emails sent from unknown addresses often are used to deliver malware. Also, do not trust ads on suspicious pages and avoid downloads from shady pages, third-party downloaders, P2P networks, etc.

Download software from official pages and stores. Keep the operating system (and installed programs) updated. Scan a computer for threats regularly. Use a reputed 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.

manual malware removal step 5Check 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".

Delete malware in Autoruns

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.

Search for malware and delete 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.
