What file do i use for Download Express to set AV check?
Use ashQuick.exe as AV scanner executable. You probably know where to enter its path in Download Express right? I think there will be no switch required.
Assuming that you installed avast! in the default folder, this is the path needed to scan downloads, C:\Program Files\Alwil Software\Avast4\ashQuick.exe
Thanks for the help.
