I need to allow my website users to upload files on my webserver.

However, I am worried that they might accidentally upload onee containing a virus.
Is there a way to do virus scsan before upload?

Also, I am worried that some people might purposely upload malicious scripts and stuffs onto the server.

How do I prevent all these?

Many thanks
