I know that there is a trojan in my outlook.pst file, but TDS-3 does not find it. The trojan is in a message in the "Deleted Items" in my personal folders. I know it is there because when I save the attachment from that message to my Desktop and scan it, TDS-3 notifies me that it's infected. However, as long as the attachment is left in the message in "Deleted Items" in Outlook, TDS-3 will not find it-even doing a "Full System Scan". Why?
