More about malware like Nitro Stealer
Usually, information stealers can gather keystrokes (record keyboard input), capture screenshots, monitor network activity, and collect other information from infected systems. Threat actors use malware of this type to steal sensitive information (e.g., credit card details, ID card information, login credentials, autofill data, clipboard data).
Cybercriminals use obtained information to steal online accounts (e.g., banking, social networking, email, gaming accounts), identities, make fraudulent purchases/transactions, blackmail victims, and other purposes. Thus, having a computer infected with an information stealer like Nitro Stealer can cause numerous problems, including monetary loss.

More about information stealers
Some information stealers are visible as running processes (those processes can be disguised as legitimate Windows processes). Alternatively, they can be configured to be running without visible processes. Moreover, information stealers often use various techniques to avoid antivirus detection.
How did Nitro Stealer infiltrate my computer?
Threat actors distribute malware via emails, fake installers for cracked software (and cracking tools), unreliable sources for downloading software, Trojans, and fake updaters. Their emails contain malicious attachments or links. Typically, such emails are disguised as important/urgent/official letters from legitimate companies or other entities.
How to avoid installation of malware?
Do not open attachments (or links) sent from suspicious or unknown email addresses, especially when such emails are irrelevant. It is very common for emails of this kind to be used to distribute malware. Also, use official pages and platforms (and direct links) to download files and software. Do not trust other sources.
Keep the operating system and installed programs up to date. Update and activate them properly - use tools provided by the official software developers for that. 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.
