Scanning the files that are uploaded to the server

[Guest]

Hi,

We have an application where the user can upload photos/documents to our
web server. Like Yahoo, we would like to scan the file before uploading it to
our web server. If a virus is found, we would like to notify the user. We are
looking for some virus scan dll that we can use to scan from inside our
application. Are there any companies that provide the dll with these
functionalities? Please let me know.

Thanks,
