This is what I am getting from HELP in BitDefender Internet Security 2017
How do I scan a file or a folder?
The easiest way to scan a file or folder is to right-click the object you want to scan, point to Bitdefender and select Scan with Bitdefender from the menu.
To complete the scan, follow the Antivirus Scan wizard. Bitdefender will automatically take the recommended actions on detected files.
Well I don't get anything with BitDefender in the contex-menu when right-clicking a file or folder. I don't know wht that is? Maybe because I'm using Danish versions of Windows 10?
It is the same at both my computers, and both are standard installations of BitDefender
So how do I scan a single folder or a single file??
