The dce65.nfc.trendmicro.com is the URL of Damage Cleanup Engine (DCE) 6.5 for the normal file checking. This process checks if the file is in the white list. When DCE detects or cleans a file, it will do a normal file check using dce65.nfc.trendmicro.com. This prevents DCE from cleaning a file within the white list.
