I\'m building a web application in which I need to scan the user-uploaded files for viruses.
Does anyone with experience in building something like this can provide
You can try to use DevDragon.io.
It is a web service with an API and .NET client DevDragon.Antivirus.Client you can get from NuGet. Scans are sub 200ms for 1MB file.
More documentation here: https://github.com/Dev-Dragon/Antivirus-Client
Disclosure: I work for them.
