How to Exclude a File or Folder from Windows Defender Scan In Windows 10

Don't want Windows Defender to scan a folder? Here's a simple way to exclude a file or folder in Windows Defender in Windows 10.
Windows Defender is the built-in and default antivirus software in Windows 10. Unlike other third-party antivirus software, Windows Defender runs silently in the background and provides real-time protection. In case you don't know real-time protection is nothing but Windows Defender being on a constant watch for any potential harm.

In addition to the real-time protection, Windows Defender also scans your system on schedule. While scanning it looks at each and every folder and flags them if necessary. This is a good thing because you don't have to worry about some forgotten folder containing some sort of PUP (Potentially Unwanted Software) or virus. However, there will times when Windows Defender flags perfectly normal folders or files as a virus.
For example, I always have a local copy of all Nirsoft tools. Due to the nature of those tools, Windows Defender flags them as viruses. This is called a False Positive. To avoid those kinds of false positives, you can exclude entire directories or folders in Windows Defender. Let me show you how.

The best thing is, Windows Defender allows you to add exclusions based on folder, file, file type, or process. Though the options are buried deep, it is very easy to do. Just follow the steps as it and you will go good.
1. Open Windows Defender by searching for Windows Security in the start menu and clicking on the result. In Windows Defender, click on the Virus & Threat Protection option.
