FourEngine.exe is a utility that comes with Asus computers. It is an EPU that helps regulate power consumption, thereby optimizing your PC to use less power. It's an environmentally-friendly application that I don't recommend uninstalling.

This application is the part of the 'ASUS EPU-4 ENGINE' - It's a CPU/Hardware monitor included with various ASUS motherboards. Usually located in 'C:\Program Files (x86)\ASUS\EPU-4 Engine' or similar directory. Not harmful.

Part of the Asus motherboard EPU-4 driver. Safe.
   
I installed it with my ASUS P7P55D-E LX motherboard. Comes with the ASUS EPU-4 Engine, which is used for power management. I tried to make my PC less noisy by enabling it, but my case fans make my PC noisy anyway. Use it, if you want to save some electricity costs.

I believe it might have something to do with quad-core CPU's, it was there the moment I first booted my PC.

Best practices for resolving FourEngine issues

A clean and tidy computer is the key requirement for avoiding problems with FourEngine. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the FourEngine.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
