I am currently developing a social networking site using RoR that uses  
the attachment\_fu plugin to handle image uploads. I also want to  
enable users to upload photoshop files, but am worried about security  
vulnerabilities because I want other users to be able to download  
these photoshop files. What is to stop someone from uploading a  
malicious file (i.e. virus) just by changing the extension? I don’t  
want someone downloading a file with a virus on it from my site. Is  
there any way to screen files for viruses when they are uploaded in  
RoR? Any thoughts? Thanks.

Have you considered using ClamAv?
