How to Use Windows Defender to Scan a Folder for Malware

Windows 10 comes with a free built-in antivirus program called Windows Defender that offers real-time protection and the ability to performs scans of your computer.

It also allows you to perform a Custom scan that lets you specify the specific folder or drive you would like to scan for malware. As you only need to scan that one folder, the scan time will be much quicker than scanning an entire machine.

Below we have provided two methods that you can use to perform a custom scan of a particular folder.

Method 1: Right-click on a folder and scan it
