G.exe is a process that prevents Windows computers from restarting and that may sometimes be related to a Trojan virus. If you get an error that tells you the computer cannot restart because of G.exe, it’s best to check your PC for malware.

In some cases, the G.exe process isn’t something malicious, but rather a bugged process that simply won’t close normally and is thus preventing Widows from restarting properly. You can still perform a hard restart of the computer by holding down the power button until your machine shuts down, waiting for about 10 seconds, and then start the computer normally, but if the issue with the G.exe continues, it’s advisable to investigate it and, most of all, check your computer for the presence of any malicious programs. If you can see the G.exe process in the Task Manager, you can try quitting it, restarting your computer, and checking the Task Manager to see if the process has been activated again. If it is still in the Task Manager, this could potentially indicate that a malware program is launching it every time you start your PC, in which case you’d need to clean your computer from the malware. A lot of researchers confirm that the G.exe is often associated with a dangerous Trojan Horse known as Graybird.Q

The G.exe Virus

The G.exe virus is a malware program that uses the G.exe process as a disguise in order to evade detection. The G.exe virus could be related to a Trojan Horse known as Backdoor.Graybird and may introduce more malware to your PC.

If you have indeed been attacked by the Graybird Trojan/Backdoor virus, then your system and data are in serious danger, and you’d need to take immediate action to eliminate the malware. If the Trojan is allowed to stay on your computer for long, it may steal sensitive data, corrupt your files, spy on your online and offline activities, exploit your computer’s hardware resources for cryptocurrency-mining, or even introduce additional malicious programs to the system, including Ransomware, Rootkits, Worms. Etc. You should most definitely do everything you can to ensure that your system is secure and that any malware that may currently be in it gets deleted ASAP.

G.exe on Windows 10

G.exe on Windows 10 is a process in the Task Manager that would prevent your computer from shutting down or restarting. Often, the G.exe process on Windows 10 is not a threat, but it may sometimes be linked to a dangerous Trojan Horse.

Though most Trojans are very sneaky and often show no discernible symptoms, there may still be certain red flags (in addition to your computer’s inability to restart properly) that may indicate that the system has indeed been infected. Unusually high CPU and RAM consumption, performance, issues, other unexpected errors, files and folders that have been moved, changed, or deleted without your permission, aggressive pop-ups that show up on your screen, the unauthorized installation of new and questionable programs and browser extensions, and more. All of those are serious red flags, especially when considered in the context of the G.exe restart error that is typically associated with this process. If you notice one or more of the aforementioned symptoms, be sure to read the instructions shown in the guide below and complete them to ensure that no malware is left on your computer.

What is G.exe?

G.exe is a file and a process encountered in some Windows systems that could be linked to the malicious Graybird.Q Trojan Horse. It’s strongly advised to do everything you can to quit the G.exe process and delete any files related to it.

If your computer has indeed been infected by the G.exe/Graybird.Q Trojan, the infection has likely come from a rogue program that you’ve willingly or unknowingly downloaded that has provided the virus with a gateway into your system. For this reason, the first step from the removal guide below would be to find the potential culprit program that initiated the infection and delete it. The way to do it has been shown below. Also, to keep your system protected in the future, make sure that you never randomly download new software that you don’t know whether you can trust. Furthermore, we strongly recommend setting your browser to always ask you to specify a download location so that new files and software cannot get automatically downloaded. Note that most browsers are set by default to automatically download new files/software without asking for any sort of approval from the user, which is why so many people get their systems infected by malware without even realizing it.

How to remove G.exe?

To remove G.exe, you need to either use a reliable anti-malware program or complete the next several manual removal steps:

  1. Uninstall any potentially rogue program that you may notice in the Uninstall a Program list of your computer.
  2. Explore the process in the Task Manager and quit any processes shown there that may be related to the malware.
  3. Delete any malware data that may be located in the AppData, ProgramData, LocalAppData, WinDir, and Temp folders.
  4. Revoke any changes made by G.exe made in your computer’s Services, Hosts file, Registry Editor, Startup items list, or Task Scheduler to fully remove the G.exe malware.

If you want to use the manual removal method, be sure to read all of the detailed instructions shown down below. If you want to remove the threat with the help of a specialized malware-removal program, we recommend using the tool linked on this page – it has been tested against similar malware and can quickly find and delete anything related to G.exe in order to secure your PC. Of course, you can also combine the manual and the automatic methods to be as exhaustive with the removal of G.exe as possible.

How to remove G.exe from Windows 10?

To remove G.exe from Windows 10, you must first ensure that the rogue program which brought it to your PC is erased. Next, you must locate and eliminate any processes, data, or settings related to the malware to remove G.exe from Windows 10.

The following instructions will provide you with an in-depth explanation of the manual steps we mentioned above. We recommend reading everything if you want to attempt the manual removal of G.exe.

Step 1

Press Winkey and R at the same time, then type appwiz.cpl in the newly-appeared Run search box and press Enter.

Now, look at the list of programs, searching for an item that could be related to G.exe. It would be a good idea to sort the list by the creation date of the programs, and then search through the most recently-installed ones first. If you notice a program you don’t recognize and/or trust, click it, click Uninstall, and perform the uninstallation by following the on-screen prompts. Make sure that you pick the removal settings (if any removal settings are available) that would ensure the full deletion of the potentially rogue program.

Step 2


*Source of claim SH can remove it.

Open the Task Manager using the Ctrl + Shift + Esc key combination, go to Processes, and search for the G.exe process. If you find it, right-click it, select Open file Location, right-click the process again, and click on End Process. After that, delete the newly-opened folder.

Whether you saw the G.exe process in the Task Manager or not, search the processes list for other suspicious entries – ones with unknown and odd-looking names and with suspiciously-high consumption of CPU and Memory. If there are any such processes in the Task Manager, look them up to see if there’s any information on the Internet about them being malicious. Also, use the following free professional malware scanner to test the files in their location folders for malware content.

If you determine that a suspicious process in your Task Manager is likely to be related to G.exe or to other malware in your system, you must quit that process and then eliminate its folder along with all that data stored there.

Step 3

It is important to not let the G.exe process or any other rogue processes be started again, so boot your computer in Safe Mode. While the computer is in Safe Mode, only the most essential system processes are allowed to start automatically, so hopefully, G.exe get activated again on its own.

Step 4

*Source of claim SH can remove it.

You should now delete any rogue data that the G.exe may have created on your PC. First, however, you need to ensure that the hidden files and folders on the computer are made visible. To do this, use the Start Menu search bar to search for Folder Options and open the first app that appears in the results. Then select the tab labeled View in the Folder Options window, find an option labeled Show hidden files, folders, and drives, enable it if it’s not enabled, and click OK.

Now you need to type %Temp% in the Start Menu and hit Enter to open the Temp folder. Everything in that folder must be deleted, so press Ctrl + A, then press the Del button, and select Yes to send the files and folders in Temp to the Bin. After that, be sure to empty the Bin.

Similarly, go to the four folders listed below, but in them only delete the files and sub-folders that have been created after you first started noticing the G.exe problem. The folders in question are:

  • AppData (%AppData%)
  • LocalAppData (%LocalAppData%)
  • WinDir (%WinDir%)
  • ProgramData (%ProgramData%)

Step 5

The G.exe malware has likely made alterations to different types of system settings – you must reverse those alterations and manually restore everything back to its normal state. To do this, use the Start Menu to search for the items that we’ve listed below, then open them, and follow the instructions we’ve shown below for each of those items.

Msconfig – In the System Configuration settings window, select Startup and, if you are on Windows 10, also select Open Task Manager. Look at what startup items are enabled on your computer and disable anything you don’t recognize or don’t trust, after which click OK to save the changes.

Task Scheduler – In the Task Scheduler window, select Task Scheduler Library (shown in the top-left), then look at the different tasks shown in the middle of the window, and delete the ones you think may be linked to the G.exe virus.

Services.msc – When you open Services, look for a service named GrayPigeonServer, right-click on it if you find it, click Properties, set the startup type to Disabled, and click OK. Also, look for other services that may be linked to G.exe and do the same with them too (look up anything you deem suspicious and/or ask us about it in the comments before you delete anything).

notepad %windir%/system32/Drivers/etc/hosts – In the Hosts file, scroll down and if you see IP addresses written below the Localhost lines towards the end of the text, copy those IPs, paste them in the comments below, and wait for a reply from us. If those IPs are potentially rogue, we will let you know that they must be removed from the file.

Regedit.exe – Before the Registry Editor opens, you will be asked for Admin approval, so click Yes to continue. In the Registry Editor, first press Ctrl + F and then type G.exe in the search bar that appears. Click Find Next to search for G.exe items and delete what gets found. Always perform one extra search after deleting an item to see if there are more items left because each search will only show a single item as a search result (even if there are more).

Next, use the search box to look for this specific item: g.exe” = “%Windir%\g.exe, and delete it if it gets found.
Finally, open the next three Registry directories from the left panel, look in them for entries with strange, random-looking names such as “3029ue08tu0eik0923utrje02930”, and inform us in the comments if you find anything that looks like this – we will tell you is anything needs to be done about it.

  • HKEY_CURRENT_USER > Software
  • HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Run
  • HKEY_CURRENT_USER > Software > Microsoft > Internet Explorer > Main

If G.exe is still in the system

At the start of this guide, we mentioned that there’s also an automatic method of deleting the G.exe virus, which is what you must try in case the manual steps weren’t enough to make your computer malware-free again. If you’re still getting the G.exe error when trying to restart your computer even after completing all of the above-mentioned steps, then this means that the virus is still likely in the system, and you’d need to use a reliable malware-deletion tool to take care of the problem. The anti-malware program shared on this page is a great option for dealing with threats such as the G.exe virus and the Graybird.Q Trojan, so we highly recommend it to anyone who needs help dealing with those threats. Also, do not forget about the comments section below – feel free to ask any questions related to the guide and the removal of G.exe, and we will do our best to get back to you with a helpful answer.
