Defender Injector adds Add An Exclusion context menu item for Windows Defender

While you can manually add some files or folders which you want to exclude from being scanned via Windows Defender UI, Defender Injector is a free tool that lets you add Add an exclusion to the Windows Defender context menu for files. Using this context menu item, you can add a file to the Exclusion list with a click.

Add An Exclusion context menu item for Windows Defender


When you are working on a Windows platform, it is best to stick to known and approved applications as far as security is concerned. You need to make sure that your antivirus, be it from Microsoft, or a third party app is not scanning critical files and ending up quarantining them.

One way to avoid the accidental quarantining or deleting of known good files and folders is to add these to the list of exceptions to prevent them from being scanned.

When you are going by the manual route to add files to the Windows Defender Exclusion list, you have to go through the following steps:

  1. Open Settings.
  2. Choose the ‘Update and Security’ option.
  3. Go to ‘Windows Defender Security Center’.
  4. Find ‘Virus and Threat protection settings’ and click on it.
  5. Now go to ‘Add or remove exclusions’.
  6. Find the ‘Add an exclusion’ option.
  7. Browse through and select the files, folders, processes, or file types that you want to add to the protected exclusion list.

The procedure above is simple, but imagine having to do that every time you add such a file or process that needs to be added to the list. It is time-consuming and tedious.

Defender Injector

This is where Defender Injector can help. The app adds entries to the context menu that let you easily manage Exclusions:

  • Add to exclusions
  • Remove this exclusion.

You can simply right-click on a file and select Add an exclusion.

You can also drag and drop the file or folder on its GUI. You can remove a file or folder from the exclusion list by selecting the file or folder in concern and clicking the delete button with the trashcan logo. Alternately, you can right-click on the file or folder concerned and click the ‘Delete selected’ option. This does not delete the file or folder; it only removes it from the list of exclusions.

To install, all you need to do is download the tool and extract the contents of the zip file into the location you want to store it in. Now double click the ‘dInjector.exe’ file and your Defender Injector is ready. It supports Windows 10, Windows 8.1, and Windows 8. It is only available in the English language. The steps are simple, and it makes putting files into and out of the exclusion list very easy.
