Free server side anti virus / security / trojan protection for file uploads?
问题 I am allowing users to upload photos like photo albums, and also attach files (documents for now) as mail attachments. So i assume I need some anti virus/security tool in place to scan the files first in case people upload infected stuff. So two questions: 1) Are there any 'free' or open source tools for this I can use or integrate into my environment: codeignitor php? 2) How to secure the upload area from rest of the system? Say the virus scanner fails to catch a virus and it is uploaded,
