I have found that this file belongs to the GIGABYTE C.O.M. (Corporate Online Manager) program/Taiwan. This is a web-based system management tool that allows client system hardware information such as CPU and memory and graphics card and much more to be monitored or controlled via a host. Remove this program to remove the gctray.exe file. The file is not a Windows core file.

CA antivirus idents this file as Amalum virii. It does indeed appear to be part of the Gigabyte COM program. I had to boot in to my Linux sys and manually rm the file, then as a safety measure a rescanned the Window/system32 directory and it came up fine. I subsequently uninstalled the Gigabyte COM program, don't want to re-install to test validity... just glad it's gone.

This process is needed to access the Green Charger II utility from the task bar. There should be a green battery icon in the system tray when it is running. Green Charger is a system utility provided by Compal Electronics to allow user control of the battery charge level.

Best practices for resolving gctray issues

A clean and tidy computer is the key requirement for avoiding problems with gctray. 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, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
