Usb drive - how to enable auto scan?

hi guys,

i have recently installed NIS 2009, and I have noticed that whenever I insert a removable drive (eg. USB disk) I have to right-click and select 'scan the drive' to run a full scan on it.

I am working in an area where we have to use usb drives frequently on client sides. And whenever I bring back the drive home, I see that it is almost always infected. is there a way in the "settings", that I can enable the auto-scan feature, and dont have to manually ask it everytime to do so?

any help will be appreciated.

Najaf.
