More about Muse Miner

The purpose of Muse Miner is to mine cryptocurrency using the hardware (such as GPU or ASIC) installed on the infected device. It allows operators to manage each connected miner individually. Muse Miner uses an Anti-VM technique to detect whether it is being run inside a virtual machine which prevents it from being examined by malware analysts.

Muse Miner can be disabled when the infected computer runs programs in full-screen mode and hidden when programs capable of detecting it are launched. Also, it can run at full capacity when the infected computer is idle (operating but not being used).

Moreover, Muse Miner hides in the operating system under the guise of a system file. It also allows operators to send other software (including malicious one) to connected miners via a Telegram bot and use a builder in that bot.

Cryptocurrency miners in general

Cybercriminals attempt to trick users into infecting computers with cryptocurrency miners to mine crypto at their expense. Having a computer infected with a miner usually results in higher electricity bills and decreased computer performance. It can also lead to loss of unsaved data, system crashes, and similar issues.

Examples of cryptocurrency miners are CH Miner, Pripyat Miner, Zenar Miner.

How did malware infiltrate my computer?

Most threat actors distribute malware through emails, unreliable sources for downloading software and files, fake software updaters, cracked software download pages (fake cracking tools/installers for pirated software). Computers get infected via emails when recipients download and open malicious files (attachments or files downloaded via received links).

Examples of untrustworthy sources for downloading files/programs are unofficial websites, Peer-to-Peer networks, third-party downloaders, free file hosting pages. Cybercriminals use Microsoft Office, PDF, and other documents, JavaScript files, archives, executables, and other files to distribute malware.

In all cases, the attackers seek to trick users into downloading and executing malware by themselves. It is important to mention that it is not only unsafe to execute downloads from cracked software websites but also illegal to use pirated software.

How to avoid installation of malware?

Use official websites and direct links as sources for downloading files and software. Other sources can be used to distribute malware. Remember that opening attachments and website links in irrelevant emails sent from suspicious or unknown addresses can cause computer infections. Thus, carefully xamine emails before opening their contents.

Always use official tools (or functions) provided by official software developers to update and activate any installed software (and the operating system). 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.

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.

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.
