The Coinhive Miner Trojan is commonly bundled with other free programs or browser extensions that you download off of the Internet. Unfortunately, some free downloads do not adequately disclose that other software will also be installed and you may find that you have installed Coinhive CPU Miner without your knowledge.
Once this malicious program or browser extension is installed, the Coinhive Miner will inject an in-browser Monero miner from coin-hive.com/lib/coinhive.min.js, which uses more than 90% of your CPU’s power and graphics cards power. What this means, is that when the miners are running you will find that your computer is running slower and games are stuttering or freezing because the Coinhive Miner Trojan is using your computer’s resources to generate revenue for themselves.
This will cause your CPU to run at very hot temperatures for extended periods of time, which could shorten the life of the CPU.
When infected with the Coinhive Miner, other common symptoms include:
- Very high CPU and graphics cards usage
- Web browser is using more than 50% of the CPU power
- PC connects to coin-hive.com/lib/coinhive.min.js
- Windows minimize and maximize slowly, and programs run slower
- Programs don’t launch as quickly
- General slowness when using the PC or Web Browser
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place. It goes without saying that you should not install software that you don’t trust.
