If you want to be safe then deleting the scheduled task is advised.
- Do Windows+R and type regedit
- Navigate to the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\ CurrentVersion\Schedule\TaskCache\Tasks\
- Carefully go through all the available entries. The GWX entries will have random hash values, so look in the right pane & identify the correct ones. They should have the string GWX under Path. There should be around six of them.

Malicious gwx.exe file
It is a Microsoft signed file. Therefore, the technical security rating is 1% dangerous. However, many cybercriminals use names of legitimate files to disguise their malicious and malware programs and that might cause financial, data loss, privacy issues, and other problems. The legitimate gwx.exe file is typically located in one of these directories:
If a gwx.exe file is not in the above-said location it is very likely to be a malicious file. Similarly, if a file has a different name i.e. not gwx.exe but Gwx.exe, or something like it to confuse the user, then it should be classed as a threat. Moreover, malicious files have graphical icons in place of simple “system” icons. If a malicious file is placed on the system (a malicious process running in Task Manager), it is recommended to run a full virus scan using reputable anti-virus (or anti-spyware) software.
Moreover, if you have already upgraded to the latest Windows version, you shouldn’t see this entry. So, carefully check the system with an anti-virus program if gwx.exe running is suspicious to be malware which is trying to hide under the name of a legitimate system component.

Method 3: Manual Removal
Manual malware removal is not an easy task and requires a certain skill level. To remove malware manually, the first step is to identify the name of the malware that has to be removed e.g. a suspicious program running on a user’s computer:
By checking the list of programs running on your computer e.g. by using task manager, and after identification of a program that looks suspicious, the following steps are recommended:
- Download Autoruns program by Microsoft which shows auto-start applications, file system locations & Registry:
- Restart the computer
- When system boots press the F8 key multiple times until you see the Windows Advanced Options menu,
- Then select Safe Mode with Networking from the list.
- Run the Autoruns.exe file after Extracting the downloaded Autoruns archive.
- Now in the Autoruns application click “Options” at the top
- Uncheck the “Hide Windows Entries” and “Hide Empty Locations” options
- Click the “Refresh” icon.
- Carefully check the list provided by the Autoruns application, & locate the malicious file that has to be removed.
- Note down its full path & name. Remember that some malware programs hide in process names under legitimate Windows process names. At this stage, it is very important not to remove any system files. When the suspicious program is found that has to be removed, right-click over the name of the process & choose “Delete“.
- Removing the malware through the Autoruns application ensures that the malicious program will not start automatically on the next startup of the system & now you should search the malicious name on the system. Remember to enable search for hidden files and folders before continuing. If the malicious file name shows in the search results, remove it.
- Now Reboot the system computer in normal mode.
Following the above steps will remove any malware from the system but keep in mind that manual threat removal requires advanced computer skills. And if you are not up to the task, leave malware removal to anti-virus & anti-malware programs. Moreover, these steps may not work with advanced malware infections. And as it is said “Prevention is better than cure” so, keep your computer safe, always keep the operating system updated and use updated anti-virus software.
