which partition should i scan

just a query i have,
if the Nod32 AMON scans all the files accessed, read and executed do i need to scan my D partition as it only contains my documents and personnel files.
Sould i run On Demand scans just for my C drive partition as it is more prone to viruses attacking?
The C Drive only has Windows Vista installed on it.

Personally I’d scan all drives/partitions at various intervals,the reason being that you might have saved a file containing a new variant of malware that bypassed the scanner at the time of saving and subsequently updated detection might find it.Having said that if you opened the infected file the on-access scanner would flag it up once detection was available,but my thinking is malware is better removed than left even if it’s dormant. :■■■■
