Blocking on computer

Why is this happening? Is it an external threat? Something seems to be trying to get to an external drive with previous backups.

If it is an internal issue, can I stop it?

Blocked unauthorised process (C:\Program Files\Bitdefender\Bitdefender Security\bdservicehost.exe) accessing file (\Device\HarddiskVolume9\BACKUPS e7440\C554E16C14B5CEF2-00-00.mrimg)
