The genuine flux.exe file is a software component of f.lux by Flux Software. f.lux is a multi-platform application that adjusts display color temperature according to the time of day. Flux.exe runs the f.lux application. This is not an essential Windows process and can be disabled if known to create problems. f.lux automatically adjusts the device's color temperature according to the time of day, according to a user-specified location based on a location name, geographical coordinates, or a ZIP code. The display colour is automatically changed to a warmer tone at sunset and is reverted back to the original at sunrise. The program was designed to reduce the intensity of blue-white light at night, with the intention of improving the effectiveness and quality of sleep. f.lux was created and first released by Michael and Lorna Herf in February, 2009.

Program that adjust colours of your screen to match daylight and therefor might be helpful if you use your PC during later hours.

f.lux is a program that changes the colour of your screen (removing the colour blue at night, seeing the colour blue is believed to release a hormone that makes you think it's the sky and makes you less sleepy) you or someone sharing your computer downloaded this purposely.

screen brightness adjuster
Downloaded knowlingly from the web to dim the monitor screen at night. Bethany (further information)
I've used it for over 2 years and haven't ever had a problem with it. Antivirus, spyware, malware removers have never detected it. Comodo hasn't detected anything either. I don't believe it's dangerous. Alen
f.lux is an external program that makes the color of the computer's display adapt to the time of day, warm at night and like sunlight during the day. Stefan (further information)
Popular program for many years now, if you installed f.lux, there should be no reason to worry of this process. It's good for people who stare at their computer screen late at night, and automatically adjusts lighting/color through calibrating with sun rise/sun down in your location. You can temp disable it for color sensitive work, as well as set it to movie mode. I would recommend having this. sam
STM lists my flux as 'potentially dangerous'. I'm having problems with cursor control and control of audio (speakers turned on & off w/o my action.) Mark Harder

This exe is not related to the f.lux screen utility by Flux Software LLC Lorna Herf
It works, but you have to adjust to your preferences - Hans G. Andersen
It might be possible that flux can install adware and other software without user's permission. After installing flux, I noticed that some software just appear on my PC out of nowhere (Opera, VLC player). One day, I found my pc to be infected with some adware (mystarsearch, cinemaP). I have not install any new thing after flux, so it is likely this is caused by flux itself. Vincen
It is malware. The shills that rate this any higher than dangerous must be ignored. A shady "PC Cleaner" process was associated with flux.exe. Wesley
It's a screen adjusting program that changes the overall screen color based on the time of day... I forgot I even had it installed. There should be a taskbar icon for it where you can change settings or turn it off. Jason Turner (further information)
f.lux incorporates a keylogger, which they claim is harmless, but some rogue version was able to compromise all the passwords of a user on my network who received an extortion email from a hacker who claimed he had all of her passwords and would sell them to gangsters unless she paid him a ransom. Oddly, he didn't demand any cryptocurrency, only cash. The subject line of the email included one of her passwords, so she was terrified that he had all of them. Boris Badenough (further information)

Best practices for resolving flux issues
A clean and tidy computer is the key requirement for avoiding problems with flux. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
To get your computer running as fast as it did on day one, you can 8reset your PC. Your personal files will remain intact, but any programs you installed will need to be reinstalled.
To help you analyze the flux.exe process on your computer, the following programs have proven to be helpful: ASecurity 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. A good Bantivirus software detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
