How to remove Bird Miner from the operating system
Written by Tomas Meskauskas on (updated)
What kind of malware is Bird Miner?
Bird Miner is malicious software that uses computer resources to mine cryptocurrency via emulation. Research shows that it runs two miners and, therefore, it consumes extensive resources. Cyber criminals distribute Bird Miner using an installer for a 'cracked' (pirated) version of ValhallaVintageVerb software.
More about Bird Miner
Bird Miner is a malOnce cryptocurrency miner similar to Bird Miner. When installed, it starts using computer resources (e.g., CPU, GPU) to mine cryptocurrency.
Software of this kind achieves this by solving mathematical problems. It can mine cryptocurrency faster on computers with more powerful hardware, and thus generates more revenue for cyber criminals responsible.
Typically, computers that have cryptocurrency miners installed and running on them start operating slower or even at the level where they virtually cannot perform any other tasks. Therefore, the operating system might start crashing or stop responding, which can result in loss of unsaved data, unexpected shutdowns, hardware overheating, etc.
Note that high computer hardware usage caused by cryptocurrency miners causes greater electricity consumption, and hence higher electricity bills.
Research shows that this particular miner is designed not to run on the operating system (not to mine cryptocurrency) when Activity Monitor is launched - this is so that users do not notice its processes running the malicious software and using computer resources to mine cryptocurrency via emulation.
Research shows that it runs two miners and, therefore, consumes significant resources.

Conclusion
Another example of a cryptocurrency miner designed to run on Mac computers is LoudMiner. Generally, users install mining malware inadvertently - cyber criminals use various methods to deceive people into installing software of this kind onto their computers. The most commonly used methods to distribute this and other malware are described below.
How did malware install on my computer?
Bird Miner is distributed via an installer designed to install a pirated/cracked version of the ValhallaVintageVerb program. It is possible that this miner is also distributed through installers that supposedly install other software (e.g., pirated Ableton Live 10 version).
Other common ways to distribute malware are via malspam campaigns, Trojans, third party (fake) software updating tools and untrusted file, and software download sources. Users infect computers through malspam campaigns (emails) when they execute malicious attachments or files that they have downloaded through links in emails received from cyber criminals.
In most cases, cyber criminals send emails that have a malicious Microsoft Office document, PDF document, archive file such as ZIP, RAR, JavaScript file or executable file (.exe) attached to them. A Trojan is a type of malware that can cause chain infections.
Once installed, it installs other malware. Fake software updating tools infect systems by installing malware rather than updates/fixes for the installed software, or by exploiting bugs/flaws of outdated software.
Examples of untrusted file/software download sources used to proliferate malware are Peer-to-Peer networks (e.g., torrent clients, eMule), freeware download websites, free file hosting websites, third party downloaders, and unofficial pages. Malicious software can be distributed through them by disguising malicious files as legitimate.
The rogue programs are installed when users download and open the malicious files.
How to avoid installation of malware
Installed programs must be activated and updated with tools or implemented functions that are provided by the official developers. No other third party, unofficial tools should be used. Note that it is illegal to activate licensed software with ‘cracking’ tools.
Files and programs should be downloaded from official websites and via direct download links. Avoid third party installers and the tools/sources mentioned above. Do not open website links or files in irrelevant emails that are received from unknown, suspicious addresses.
These bogus emails are often disguised as official and important. Regularly, scan your computer with reputable, up-to-date antivirus or anti-spyware software. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
