3. Whitelist Discord Files in Your Antivirus

If you are getting this issue while Installing Discord. Some users experienced a situation where their antivirus (Avast in most cases) accidentally quarantined some of the installer files needed for the update or for the installation to finish, thinking it was a potentially dangerous file.

You will have to locate the file and whitelist it in order for the installation process to continue. Follow the instructions below in order to do this with your Avast antivirus.

  1. If Avast is already open, you can locate it at your taskbar, right-click on it and select open. If Avast does not load on startup, you can always start it manually by locating it in Start.
  2. Proceed by selecting Scan >> Scan for Viruses >> Quarantine (Virus Chest). The quarantine button is located somewhere at the bottom of the page.

  1. When you open the quarantine you should notice some Discord-related files. Restore these files and click “Add to Exclusions”. If some of these files have already been generated by the installer, click Overwrite to replace these files and launch the installation again.

In order to prevent this confusion from happening again with a different file, you will need to set up the installer and the tool itself as an exception in the Avast antivirus, depending on whether the error occurred during the installing phase or after it has already been installed.

  1. Open your Avast antivirus in any of the ways we mentioned earlier. After that, navigate to Settings >> Exclusions. This is where users are free to put files that should not be looked after and which should not be scanned or registered as a threat.

  1. Add the installation folder of Discord in order to exclude it from scanning. If the error occurs when installing the tool, navigate to the location where the installer is located and choose it.
  2. After that, close your Avast window and try running or installing Discord again and check to see if the error is gone.

Note: If this whole process doesn’t work, you might need to completely uninstall your antivirus and run the installer again without the antivirus installed. After the installation completes successfully, reinstall your antivirus and this should fix the fatal javascript error occurred in discord.
