I don't know if this has been reported yet, but scanning a file/folder via the context menu (scan and clean/scan without cleaning) is not working.
I'm on WIN11 22H2 (22621.819) and running Eset NOD32 Antivirus 16.0.22.0.
Expanding the context menu (show more options, Shift+F10) and selecting "Scan with Eset NOD32 Antivirus" works as expected. Dragging and dropping a file/folder on NOD32 user interface also works.
