Not everyone stores their files on the local drives. A lot of us use external or portable drives to store sensitive data. We can scan them when they are plugged into our machines using two different methods. This article will show you how to scan external drives via the context menu entry and by scanning using a custom scan.  
For this article we are going to use the two methods to scan this removable drive, Drive E:

Option 1 - right-click

  1. Open the file manager (file explorer in Windows).

  2. Right-click on this file, folder or drive, which should be scanned.

  3. From the context-menu, select Scan with Malwarebytes.

Option 2 - custom scan

  1. Open Malwarebytes and click on Scan (in the right menu).

  2. Select the Custom Scan.

  3. Click on Configure Scan, a new Windows shows the customer scan.

  4. On left side, you can configure same options for the scan.

  5. On right side, you can select, files, folder or drives, which should be scanned.

  6. Click on Scan Now to start the scan.
Note: If you do not see your drive, use the right-click option. In some cases, Windows does not allow the display of the drive in our application.
During a custom scan, the scan time increases because all files and folder which are selected will be scanned. That means the scan is running much longer, than a normal thread scan.  Also, the usage of CPU and HDD can increase to 100%, so that your computer can get very slow.
We suggest you perform a custom scan when you are not using the computer.  The same is true, when you enable the "scan of rootkits" option.
