how do i run a custom scan from CMD line?

Hi folks…

I was wondering how I could run a custom scan on AVAST5 from the cmd line.
I want to intiate a scan on a server but have it run when there is no-one using the server so overnight would be great.

can someone please give me some tips…
cheers and thanks
