CH Miner in general

CH Miner can utilize the hardware installed on the computer for mining cryptocurrency, steal information typed with the keyboard, access files stored on a computer, spy on victims. Moreover, cybercriminals can use it to infect computers with additional malware.

Having a computer infected with CH Miner can result in higher electricity bills (and hardware overheating, loss of unsaved data), additional computer infections, identity theft, loss of access to personal accounts, monetary loss, and more. Examples of other miners are Pripyat Miner, Punisher Miner, Zenar Miner.

How did CH Miner infiltrate my computer?

Typically, threat actors distribute malware using pirated software download pages (and other unreliable sources for downloading files and programs), emails, fake software updating tools. Their goal is to trick users into executing downloaded malware by themselves.

The most commonly used files to trick users into infecting their computers are malicious Microsoft Office, PDF documents, JavaScript files, executables, archives containing malicious files. Emails used to distribute malware have malicious attachments or links in them. Typically, such emails are disguised as official/important letters from legitimate entities.

Examples of unreliable sources for downloading software and files are Peer-to-Peer networks, free file hosting pages, various shady sites, third-party downloaders. Legitimate (but compromised) pages can be used to trick users into executing malicious drive-by downloads too.

How to avoid installation of malware?

Remember that opening attachments (and website links) presented in irrelevant emails received from unknown, suspicious addresses can lead to computer infections. Always use official pages (and direct links) as sources for downloading files and software. Do not trust downloads from other sources.

Use tools provided by the official developers to update and activate installed programs. Keep them up to date and scan a computer for threats regularly. 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. 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.
