W32/CoinMiner is a Trojan Horse that uses the infected computer’s resources to mine digital currency (Monero, Bitcoin, DarkCoin or Ethereum) without user permission.
W32/CoinMiner Trojan will use more than 70% 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 W32/CoinMiner 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 a PC is infected with W32/CoinMiner malware, common symptoms include:
- Very high CPU and graphics cards usage
- Windows minimize and maximize slowly, and programs run slower.
- Programs don’t launch as quickly.
- General slowness when using the PC.
