What is Null0.exe?

The Null0.exe process is part of a Trojan Horse that uses the infected computer’s resources to mine for digital currency without user permission.

When this malicious program is installed, the Null0.exe process will use more than 90% of your CPU’s power and graphics card 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 Null0.exe Miner 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 Null0.exe CPU Miner Trojan, other common symptoms include:

  • Very high CPU and graphics cards usage
  • Null0.exe and other suspicious processes will run in the background.
  • Windows minimize and maximize slowly, and programs run slower.
  • Programs don’t launch as quickly.
  • General slowness when using the PC.

How did Null0.exe get on my computer?

Null0.exe Trojan is installed by the users, whether that is knowingly or not. Often, this type of program is offered through advertisements or bundled with other programs, leaving the user puzzled about where this software came from.

You should always pay attention when installing software because often, a software installer includes optional installs. Be very careful what you agree to install.
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.
