Remove App_loader.exe and SystemUpdate64x.exe CPU Miner Trojan

The App_loader.exe and SystemUpdate64x.exe processes are part of a Trojan Horse that uses the infected computer’s resources to mine for digital currency without user permission.

The malicious program that runs the App_loader.exe and SystemUpdate64x.exe CPU Miner is commonly bundled with other free programs 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 App_loader.exe and SystemUpdate64x.exe CPU Miner without your knowledge.

Once this malicious program is installed, the App_loader.exe and SystemUpdate64x.exe processes will use more than 80% 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 App_loader.exe and SystemUpdate64x.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 App_loader.exe and SystemUpdate64x.exe CPU Miner Trojan, other 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.
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.
The below instructions are for Windows users, however we also have an Android guide and a Mac OS guide which should help clean up your device.
