Gwx.exe virus removal guide
What is gwx.exe?
The gwx.exe file is a part of the Microsoft Windows operating system. Its purpose is to upgrade Windows operating systems from earlier versions to Windows 10. The gwx.exe file is placed in the "C:\Windows\System32\GWX" folder, however, like many legitimate processes, its name could be used to disguise a malicious file/process.
GWX - Get Windows X (10) - has an associated gwx.exe file designed to show notifications to promote this Windows version. It was used to promote the latest version of Windows by encouraging users to upgrade their older versions to the new one free of charge. This advertising campaign has already ended, however, research shows that some people are still receiving offers to upgrade installed operating systems. As mentioned, gwx.exe is a legitimate file, however, many cyber criminals use names of legitimate files to disguise their malicious programs such as Trojans and other malware that might cause financial, data loss, privacy issues, and other problems. If a particular file is not in the correct location (in this case, the genuine path is "C:\Windows\System32\GWX"), it is very likely that it is a malicious file. Similarly, if a file has a different name (not gwx.exe, but perhaps Gwx.exe, or another), it should be classed as a threat to the operating system. Additionally, malicious files/processes have graphical icons when in fact they should have simple "system" icons. In any case, do no take action without verifying that a file is misplaced or has a different name. Unfortunately, mistakes happen and anti-virus programs often detect legitimate files as harmful. These are called 'false positive' results, and can cause removal of legitimate or important system files. If you believe that a malicious file is placed on the system (a malicious process running in Task Manager), we recommend that you run a virus scan using reputable anti-virus (or anti-spyware) software.

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Malwarebytes.
In many cases, malicious processes and files are mistaken for legitimate ones and vice versa. To avoid causing damage to the system (by removing a legitimate file or not removing a harmful one), we recommend that you 'Google' it to determine if any actions should be taken. Some examples of cases of possible or existing 'false positive' detections are Csrss.exe, Fuerboos, and Trojan.gen.npe.2.

How to avoid installation of malware?
Do not open links or attachments that are presented in irrelevant emails, those received from unknown, suspicious addresses, and so on. Download software from official and trustworthy websites, and not using third party downloaders and the other tools mentioned above. Update installed software using tools and implemented functions provided by official software developers only. Paid software should be activated properly. Do not use 'cracking' tools, since they can cause computer infections and using them is a cyber crime. Have a reputable anti-virus or anti-spyware suite installed and enabled. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck the "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application, and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
