Prefer to check it yourself? The manual checks follow.
gui.exe in the Gigabyte Smart 6 folder on a PC with a Gigabyte motherboard is the interface of that program. It is a legitimate file of the Taiwanese manufacturer and is not essential for Windows, so it can be disabled if it causes any issues.
A gui.exe that uses too many resources, sits outside the Smart 6 folder or appears on a PC with no Gigabyte software may be an imposter. Cybercriminals are known for camouflaging their creations as gui.exe, so check the file before you trust it.

What gui.exe does
gui.exe is the graphical user interface of Gigabyte Smart 6. The program is preinstalled on many PCs with Gigabyte motherboards and consists of six utilities that help Windows devices boot up faster, increase system performance and similar tasks.
The file is a legitimate file of the Taiwanese manufacturer and is not essential to Windows. Disabling it does not stop Windows from running, but the Smart 6 interface stops working with it.
Because the name is short and generic, cybercriminals have camouflaged their own files as gui.exe. Hobbit.416 and Noknok are two notable infections that used the name.
About .exe files. An .exe file is a program. It runs as a process you can see in Task Manager, so its name, folder and publisher are what to check.
How to check it
The file is trusted when it is in the Gigabyte Smart 6 folder, belongs to software you installed or that came with the motherboard, and is signed.
- Find the process in Task Manager. Press Ctrl+Shift+Esc and look for gui.exe on the Processes or Details tab. Note how much CPU, memory and network it uses.
- Open the file location. Right-click the process and choose Open file location. The genuine file is in the Smart 6 folder inside the GIGABYTE program folder. A copy in C:\Windows, System32, Temp or a user profile folder is not where the program installs.
- Check the digital signature. Right-click the file, choose Properties, then Digital Signatures. The signer should be Gigabyte. In PowerShell, using the path from the previous step:
Get-AuthenticodeSignature "<path to gui.exe>" | Format-List Status, SignerCertificate - Confirm Smart 6 is installed. Open Settings > Apps > Installed apps and look for Smart 6 or other Gigabyte software. If none is installed and the PC has no Gigabyte motherboard, nothing should be running gui.exe.
- Scan the file and the PC. Run a full scan and an offline scan with Microsoft Defender (Windows Security > Virus & threat protection > Scan options). Scan the particular file too: right-click it and choose Scan with Microsoft Defender.
A signed file in the right folder is the genuine interface. It cannot show that the rest of the PC is clean, so scan as well.
Do you need gui.exe?
Only if you use Gigabyte Smart 6. Windows does not need it. Do not delete the file by hand: remove the program the proper way, and trust a scanner before you delete any file, as deleting files may result in various system issues.
- Keep it if you use Smart 6. gui.exe is the interface of the program. Without it the Smart 6 utilities cannot be controlled from their window.
- Stop it from starting. Press Ctrl+Shift+Esc, open the Startup apps tab, select the Gigabyte or Smart 6 entry and choose Disable. Windows then starts without it. This is reversible.
- Uninstall the program, not the file. Open Settings > Apps > Installed apps, select Smart 6 and choose Uninstall. If it does not uninstall, a forum user advises running the uninstaller from the Smart 6 folder with Run as administrator.
- If the file is not Gigabyte's. If the checks show a gui.exe outside the Smart 6 folder, unsigned, or on a PC with no Gigabyte software, run a full scan and an offline scan with Microsoft Defender and let it remove the threat.
Warning signs
| What you see | What it means |
|---|---|
| gui.exe using too many resources | The interface of a utility is idle most of the time. Constant high CPU, memory or disk use is a reason to check the file and scan it. |
| gui.exe outside the Smart 6 folder | Not where the Gigabyte program installs. Malware camouflages itself under this name, as Hobbit.416 and Noknok did. |
| No Gigabyte motherboard or Smart 6 on the PC | Nothing should be running this file, so a copy is suspect. |
| No digital signature or a signer other than Gigabyte | The manufacturer's file is expected to carry Gigabyte as publisher. |
| Any other suspicious activity from the process | Unexpected network connections, new startup entries or pop-ups tied to gui.exe are signs of an imposter. Scan the file. |
