What kind of malware is Muck?
Muck is an information-stealing malware primarily designed to extract sensitive data from infected devices, focusing on web browser data. This malware can cause victims serious privacy and security issues. Therefore, it should be eliminated from infected computers as soon as possible.
More about Muck
Information stealers like Muck often target web browsers. This is because web browsers often store various personal and sensitive data, including login details (e.g., usernames and passwords) for online accounts, payment information, and other information that can be used for malicious purposes.
Using login credentials extracted from web browsers, attackers can access social media, email, gaming, banking, and other accounts. With this access, they can spread malware, obtain more personal information, make fraudulent purchases and transactions, send fraudulent messages to other people, etc.
If Muck captures payment or similar information, attackers may initiate unauthorized transactions, deplete bank accounts, or charge purchases to victims' credit cards. The data extracted by the malware may also be used to steal identities. Additionally, Muck can harvest cookies.
If Muck captures these cookies, attackers can use the stolen session tokens to gain direct access to accounts without needing login credentials, bypassing standard security measures such as two-factor authentication (2FA). Cookies can also contain information about a user's browsing habits, search history, and similar data.
Overall, Muck can lead to financial losses, privacy violations, account takeovers, and other problems for victims. If there is a reason to believe that a computer is infected with this or similar malware, the system should be scanned using a reliable security tool immediately.

How did Muck infiltrate my computer?
Cybercriminals spread malware using various deceptive tactics, including sending emails with malicious attachments or links, running technical support scams, and embedding malware in pirated software, cracking tools, or key generators to lure users into executing it on their computers.
Malware can also be distributed through malicious ads, peer-to-peer (P2P) networks, third-party downloaders, free file hosting sites, software vulnerabilities, and infected external devices like USB drives. Often disguised as harmless files, such as MS Office documents, PDFs, executables, script files, or archives, malware can infect users’ systems if users download and run it by taking certain actions.
How to avoid installation of malware?
Always carefully examine unexpected emails from unknown senders and avoid opening any links or attachments they contain. When downloading software, stick to reputable platforms, such as official websites and app stores. Be wary of pop-ups and ads on suspicious sites, and do not agree to receive notifications from websites of this kind.
Lastly, keep your security software, apps, and operating system up to date, and use reputable security software to protect against malware and other threats. 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.
