Scanning problem & Trojan detection

Under 'Nod32 Manual Scanner' when i click on 'scan & clean', under
'Scanning Log' tab the following messages appear in blue:
Scanning memory: Not performed(option disabled)
Scanning MBR and boot sectors: Not performed(option disabled)

I set up the Nod32 antivirus according to the setting posted by Blackspear
on this forum.
1) How do I enable these settings? I figured they'll be important to detect the viruses.
2) Under 'Threat Log', I have a 'Win32/TrojanDropper.Agent.NDN trojan,
and the 'Action' taken was 'error while cleaning-option unavailable for this type of object'. How do I delete this trojan?

Please Help! It would be greatly appreciated

 

Do not use the /scanmem- parameter if you are running nod32 from the command line, or enable that option in the on-demand scanner setup. Still, if NOD32 finds a threat residing in memory, you can only choose to skip it, and the scan will continue. When a malicious file loaded in memory is found, NOD32 will offer you to delete it. It will be deleted next time you start the computer.

That's because you have AMON set to clean files automatically. Set it to prompt for action if a threat is found and you'll be able to delete it from within the alert window.
