Virusscanning in DAP

I use Download Accelerator Plus for a while and I found out the possibility to scan for a virus in you finished download. I thought that the file to use for Norton AntiVirus was NAVW32.exe, but I don’t know the parameters for the second line in DAP, because now after every download he scans my whole PC except only the download…

What are the correct parameters to be set at the second like using Norton AntiVirus???
