Is there a way to tell Avast not to scan anything that is access from a local network location, a way to tell him that is safe and to ignore them.
Edited.
Which way do you mean that “from”?
Somebody from the network accessing the machine where avast! is installed, or the machine with avast! installed accessing some remote resources on the network?
The computer with avast accessing resources, letting it access but not letting avast scan it
I believe you can enter the corresponding masks in UNC form into the list of exclusions…
