What kind of malware is Xillen?
Xillen is an information stealer often distributed through other malware, such as Amadey. Once executed on the device, it gathers various information and sends it to cybercriminals. Having the system infected with Xillen can result in issues such as identity theft and financial loss. Thus, if detected, the stealer should be removed immediately.

More about Xillen
Information stealers like Xillen are designed to collect sensitive data from an infected system and send it to an attacker. Their main goal is to harvest information that can be used for malicious purposes, such as account takeover, financial theft, or identity fraud. These threats usually run silently in the background.
The data stolen by Xillen can include login credentials saved in web browsers, such as usernames and passwords for email, social media, banking, and other services. Information stealers also target browser data, such as cookies, autofill entries, and browsing history. Some stealers collect data from password managers, FTP clients, VPN software, and messaging applications.
Also, Xillen can target cryptocurrency wallet data, private keys, seed phrases, and browser-based wallet extensions. It can also attempt to gather credit card details, clipboard data, system information such as IP address, operating system, installed software, and hardware identifiers.
It is also worth noting that Xillen can be designed to use evasion and persistence techniques to remain undetected and continue stealing data. It may disable security features, check for virtual machines and sandboxes before running, and add itself to startup locations, scheduled tasks, or registry keys so it automatically relaunches after a system reboot.

Conclusion
In conclusion, information stealers like Xillen are dangerous because they can quietly collect a wide range of sensitive information from an infected system. They give attackers the ability to commit fraud, steal identities, access accounts, and more. If a system is infected, users should run a security tool to remove malware.
Additional examples of information stealers are DotStealer 2.0, Evelyn, and AuraStealer.
How did Xillen infiltrate my computer?
Xillen is known to be distributed using Amadey, a type of malware cybercriminals often use to deploy malicious payloads. The initial infection vector could be a malicious file or link in a deceptive email, a technical support scam, pirated software, a cracking tool, or a key generator.
Cybercriminals can also use malicious advertisements, compromised or deceptive websites, P2P networks, vulnerabilities in outdated software, third-party downloaders, and similar channels. Usually, infections occur after opening malicious executables, documents, or other files (or taking additional steps).
How to avoid installation of malware?
Keep your operating system and applications up to date and avoid using pirated software, cracks, or key generators, and always download programs from official websites or app stores. Be careful with unexpected emails or messages, and do not open links or attachments unless you are sure they are safe.
Block notification requests from suspicious websites, and avoid clicking on ads, pop-ups, or buttons and links presented on questionable pages. 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:
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Click the "Restart now" button. Your computer will now restart into the "Advanced Startup options menu". Click the "Troubleshoot" button, and then click the "Advanced options" button. In the advanced option screen, click "Startup settings".
Click the "Restart" button. Your PC will restart into the Startup Settings screen. Press F5 to boot in Safe Mode with Networking.

In the advanced options menu select "Startup Settings" and click on the "Restart" button. In the following window you should click the "F5" button on your keyboard. This will restart your operating system in safe mode with networking.

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.
