I need to scan uploaded files on a windows server through my ASP.NET web app. However, am not aware if anti virus packages come with an "api" sort of a thing using which i can programmatically trigger the scan. If possible i would really want to avoid any kind of windows scheduling to trigger the antivirus and then report the errors.
ClamAV offers API support and is free. I am also sure that many other commercial vendors offer the same at a price (generally large).

Note: you will need to access the functionalities through P/Invokes.
