Just loaded NOD32 this evening and have not read the manual yet. I use a download manager 'Reget' and when it downloaded a file it used my old scanner nav32 and I could use a switch like /f noresults so the file was scanned but the results screen would not show unless of course a nasty was found. Is there a similar switch with NOD?? Secondly why does not want to scan a usb drive? it always gives this error "Error occurred while scanning MBR sector of the 3. physical disk. Error reading sector." As I have 2 hardrives attached with 7 partitions the only drive I can see as being "3" would be the usb drive attached to my printer for reading drives out of my camera, I can't see a way to stop NOD from trying to read this drive OR am I wrong and there is a problem with my MBR on a HD?
