Hi, To start with utmost basic practice, the folder in which these files are place should have minimum possible privileges. You could also look at removing the excute permissions completely. An local antivirus action should be set to delete as soon as it detects something suspicious. The files could be moved for screening to a sandbox like enviorment. Hope it helps.

The files could be images (jpg, gif, png), documents (doc, docx, xls, pdf), or text files(txt, csv). My question is regarding virus scanning of these uploaded files. With vulnerabilities being reported in formats like PDF, I would like to protect the users and infrastructure as much as possible. Are there any best practices for this? What products (commercial or free) should I evaluate for this process?
