Solution 2: Add Discord Installation Files to the Whitelist of Antivirus Software
We often use antivirus programs to protect files or data on our computer from unwanted threats. But, there are a handful of antimalware/antivirus programs that are known for blocking programs/applications on the computer.

So, here are the steps:
- Open the Avast by following the steps mentioned above.
- Go to the Menu option given on the top-right corner of the Avast window.
- Now, select the Settings from the drop-down list.
