SEP not scanning hidden local drive

Hello,

I need advice on the following. The customer has workstations where only C drive is visible. There is also D drive but it is hidden. If we browse from Windows Explorer to D drive, it opens.

The problem is that SEP is not scanning this local hidden drive, also we cannot run manual scan from the SEP interface and the customer said that they found a virus there. Only possible way to scan this drive is with DoScan.exe /ScanDrive D command.

Is there any way SEP to scan this hidden D drive via scheduled scan or what we can do in this situation?

Thanks in advance
