How virus scanning works?

Post by BurakUeda »

Say I sent a 40MB attachment, and MSFE is set to scan both incoming and outgoing attachments.

Will mailscanner/clamav scan the file as it downloads it, or downloads the whole file first and scan?

I believe it will download the entire attachment into a temporary file and then scan it. As I understand it, virus scanners can only scan whole files.
