virus

I am looking to see how I can go about checking if an uploaded file has a virus or not via PHP. What options exist, pros and cons of each, etc. ClamAV is a free anti virus commonly used on server applications. php-clamav is an extension for binding ClamAV to PHP.

I know it's because Delphi adds timestamps to its DCU files and these timestamps end up in the final executable
